The present study aims to investigate the biodiversity of woody vegetation along a gradient of human impacting region in the three constituent parts of Ferlo Biosphere Reserve (FBR): the core area, the buffer zone and the transition area. We conducted an inventory of 110 plots of 900 m² each. Total species richness was 49 species distributed in 32 genera within 16 botanical families. The analysis of contesimal frequency showed that Guiera senegalensis is the most common species with a presence of 75% of such records. Examination of species abundance spectrum showed that four most abundant species such as Guiera senegalensis (29.5%), Combretum glutinosum (15.9%), Pterocarpus lucens (11.6%) and Boscia senegalensis (10 , 5%). These four species represent 68% of the total individuals of the RBF and are also the four most common species. The spectrum of abundance of families showed that Combretaceae is the best represented family with almost half of the number of species (49.7%). The representativeness of biological types and geographical affinity of the species has been established for the woody vegetation in the study area. The study of diversity indices revealed that the buffer zone and the transition area are subjected to multiple uses and experiencing human action. It has a greater diversity and a level of organization with higher timber stand than the central area which is an integral conservation zone.
Diversity and abundance of terrestrial mammals in the northern periphery of ...Innspub Net
The Tanoé-Ehy Marsh Forest (TEMF), an unprotected forest that is about to be turn into a voluntary nature reserve is a forest block in south-eastern Côte d’Ivoire known as being of great importance for the conservation of biodiversity. But in the rainy season, that forest is largely over flooded and terrestrial mammals are likely to move to the periphery and make them vulnerable to anthropogenic threats. Our objectives are to determine the diversity, the relative abundance of terrestrial mammals and their spatial distribution in the northern periphery of the TEMF during the rainy season. We collected data by conducting recce surveys after interviews with local people. In total, we obtained 33 species among which ten primates’ species were identified. According to the recce survey, the African Civet (Civettictis civetta) and the Bushbuck (Tragelaphus scriptus) are the most common and abundant species in the study area with 12.7% and 12.0% of relative abundance respectively. In addition, six of the listed species are on the IUCN Red List, including Piliocolobus waldronae, a critically endangered species, Cercocebus lunulatus and Cercopithecus roloway endangered species, Colobus vellerosus, Phataginus tetradactyla and Phataginus tricuspis, three vulnerable species. Thus, the consideration of the periphery for the sustainable management of the TEMF is proving to be an imperative.

Comparative study on Population of Earthworms in Different Habitat Types alon...AI Publications
Earthworms are one of the very diverse organisms in the environment. The abundance of the earthworms relates to the different land use, human activity, biotic and abiotic factors on nature. The diversity and abundance of earthworms was studied in different habitats; broadleaved forest, chirpine forest, residential area and agriculture land with the aim to understand the variation in earthworm species in those habitats. Between the altitude 650-1450masl. a total of 20 major plots and 100 sub-plots was made to assess the earthworm diversity in selectedhabitat. Physio-chemical analysis of soil was done to know the diversity, abundance and density of earthworms. The result of study does find two orders, five families and seven species of earthworms. They were Amynthasalexandri, Metaphirehoulleti, Perionyx excavatus, Aporrectodeacalciginosa, Dichogastersp., Pontoscolexcorethrurus and Darwidasp. Broadleaved had the highest diversity with Shannon index of 2.04 and the lowest diversity was found in chirpine forest with Shannon index of 1.6. The highest richness was in the broadleaved forest with index of 0.827. Amynthasalexandri was present in all the habitats and it had the highest relative abundance of 28.12%, relative density of 32.80 per m2 and frequency of 25%. The lowest relative density, abundance and frequency was found in Darwida sp. The analysis of variance showed thatthe NPK content in the soil has effect on the density of earthworm along the altitude. In lower altitude at 650 masl. The density of earthworms was more with a high amount of NPK in soil and in higher altitude at 1450masl. the decrease in NPK showed low earthworm density. Pearson correlation showed a positive correlation with soil Physico-chemical parameters and an abundance of earthworms.
The participatory management plan is a technical, legal and social device that joins the objectives of biodiversity conservation and the socio-economic needs of local populations. This research work aims to evaluate the impact of Wari-Maro classified forest management plan implementation on the structure and specific diversity of vegetation types. The methodological approach followed is based on the comparison of the dendrometric parameters and plant diversity parameters before and after the management plan implementation. The phytosociological and dendrometric database before the management plan was compiled with data from the forest inventory conducted by PAMF project in 2004 and others work. The forest and phytosociological inventories were carried out on the plots (70) from the forest inventory of PAMF project (2004) following the same methodological principles. The Shannon diversity index decreased from 3.35 ± 0.57 bits in 2004 to 1.98 ± 0.73 bits in 2014. The average density of dbh trees ≥ 10 cm decreased from 740.37 ± 269 , 86 stems / ha in 2004 to 184 ± 100 stems / ha in 2014. The results of the 5% sample matched t-test reveal a non-significant difference between the Shannon Diversity Index of 2004 and of 2014. On the other hand, the results of the sample t-test matched at the 5% threshold, reveal a significant difference between the average density value of 2004 and 2014 for all vegetation types except shrub savannas, fields and fallows. Most of the plant species found before the management plan are still present despite the decreased in individuals’ density.

THE EFFECTS OF CLEARCUT SIZE ON THE BIRD COMMUNITY IN THE SECOND COLLEGE GRANTjoshmooney
Abstract. This study examines the effects of forest opening (clearcut) size on the surrounding forest-bird community with the objective of offering management suggestions for foresters who employ the clearcut method. I hypothesized that large and small clearcuts would have different effects on the forest-bird assemblage associated with each. I used the point-count method to assess bird abundance in clearcuts, on the edges, and 100 m into the forest from the edges of large and small clearcuts. I found that Neotropical migrant birds and forest-interior birds were the most affected by large clearcuts showing significantly lower abundance in forest areas 100 m from large clearcut edges than in forest areas 100 m from small clearcuts. Edge-open birds were more abundant in large clearcut openings and edges than in small clearcut openings and edges. Blue jays (an avian nest predator) were more abundant on the edges of large clearcuts than on the edges of small clearcuts. A recent study found that forest-interior bird abundance levels off after 100 m distance from small (0.4 ha) forest openings. This result combined with my findings suggest that small openings in the Second College Grant represent less of a disturbance to Neotropical migrants and forest-interior birds. Additionally, given higher abundances of an avian nest predator in large clearcuts, reproductive success could be much lower in areas associated with large clearcuts. Some species such as the White-throated Sparrow (Zonotrichia albicollis), however preferred large clearcuts suggesting that there are some benefits to overall bird abundance by including large clearcuts in a managed landscape.
A numerical analysis of understory plant associations in a Pinus wallichiana ...Innspub Net
The present investigation describes the structure and vegetation composition of the forest located in Murree Hills, Punjab, Pakistan. The study area is a part of Himalayans moist temperate forest. The vegetation zone entirely consists of shrubs or medium size trees. The plants give the appearance of a vast flower bed, composed principally of herbaceous species. These species are adapted to withstand the extremes of cold and desiccation. Study area range in altitude from 2100m-2300 m (A.S.L.). A total of 65 species, belonging to 62 genera and 39 families were recorded from 40 stands. Angiosperms contributed a major share while Pteridophytes contributed little to the floristic richness of the area. Data were analyzed by multivariate statistics including Cluster Analysis, Detrended Correspondence Analysis (DCA) and correlation co-efficient to detect the relations between altitudinal and some environmental factors with composition and structure of the plant communities. DCA axis 1 and axis 2 were used to interpret the data. Four vegetation types were delineated by Cluster Analysis which was then plotted on the first two axes a scattered diagram. The outcome of the cluster was confirmed by using DCA. There were significant differences in the flora composition as well as the edaphic factors along the altitudinal gradient. The results of the present investigation suggest a direct altitudinal and soil chemical factors pH, EC, cations and anions on the vegetation variation. Topography predicts species composition of the study area.
Ecosystem Carbon Storage and Partitioning in Chato Afromontane Forest: Its Cl...IJEAB
Forests trap carbon dioxide (CO2) from the atmosphere, store in the form of carbon (C) and regulate climate change. In this study, C storage and climate change mitigation potential of Chato Afromontane forest was assessed from measurement of the major pools including the aboveground biomass, belowground biomass, dead tree biomass, plant litter and soil organic carbon (SOC). The result showed that biomass accumulation was comparatively larger for natural forest than plantations due to maturity, intactness and species diversity. The total C storage capacity of the forest ranged from 107.12 Mg ha-1 for acacia plantation to 453.21 Mg ha-1 for the intact natural forest. The mean C storage capacity by major pools ranged from 1.36 Mg ha-1 for the dead tree C to 157.95 Mg ha-1 for the aboveground C pool. The forest ecosystem accumulated a total of nearly 6371.30 Gg C in the vegetation plus soil to a depth of 60 cm. Conservation of the sacred forest will have an imperative implication to net positive C addition and regulation of climate change.
Carbon stock of woody species along Altitude gradient in Alemsaga Forest, Sou...Agriculture Journal IJOEAR
Purpose: Forest ecosystems play a significant role in the climate change mitigation and biodiversity conservation. Therefore carbon determination provide clear indications of the possibilities of promoting forest development and management for mitigating of climate change through soil and vegetation carbon sequestration. The study was carried out to quantify carbon stock potential in Alemsaga Forest, South Gondar zone. Research method: Vegetation data Collection was made using a systematic sampling method; laying six transect lines with 500 m apart and 54 quadrants of 20 m X 20 m established 200 m distant to each other along the transect lines. In these plots, abundance, DBH and heights of all woody species were recorded, and soil sample was collected 1m X1m from the four corners and center of each quadrant. General allometric model was used for estimating above and belowground biomass. The organic carbon content of the soil samples was determined in the laboratory. Finding: A total of 66 woody plant species belong to 42 families were identified, Fabaceae was the most dominant families. The total mean above and belowground carbon stock was 216.86 ton/ha and 114.71 ton/ha respectively and soil organic carbon (SOC) 103.15 ton/ha. Above and belowground carbon increased as altitude decreased, but SOC increases with increase of altitude. Originality/value: Carbon stock estimation in the forest helps to manage the forests sustainably from the ecological, economic and environmental points of view and opportunities for economic benefit through carbon trading to farmers.
Abstract— This study was conducted in Gunugo watershed at Wolayitta zone to assess the amount of some soil chemical properties affected by traditional agroforestry practices and along different elevation gradients. The dominant agroforestry practices (homegarden, parkland and woodlot), and three elevation gradients (upper, middle and lower) were used to collect soil samples. One composite sample was taken from each sampling point from each soil depths, under three agroforestry practices and three elevation gradient with three replications to have a total of 54 soil samples at 20 x 20 m plot. Then the selected soil chemical properties among agroforestry practices and along elevation gradient was determined at p<0.05. The EC, pH and CEC of the top soil was significantly higher on homegarden than parkland and woodlot while EC, pH and total nitrogen of the sub soil were significantly higher on homegarden than parkland and woodlot. Further, only the top soil EC and CEC were significantly higher on lower elevation than upper and middle elevation and there was no significant difference in sub soil chemical parameters among elevation levels. In relation to this, most of the soil chemical properties show as the study area is being degraded. Therefore, are recommended for sustainable soil chemical property management. Hence, homegarden is suggested as a better agroforestry practice for rehabilitation of the area in a sustainable manner through enhanced accumulation of total nitrogen, good EC and CEC at all elevation gradients.
Diversity and distribution of butterflies in the open and close canopy forest...Innspub Net
Butterflies were sampled in Cadaclan, San Fernando La Union Botanical Garden (LUBG) of North Luzon to provide information on species-level diversity trend and distribution of butterflies on the open and close canopy portion of the dipterocarp forest from 2012-2014 using field transect method Species accumulation curve shows that additional sampling is needed for the possible turnover of species. Butterfly abundance was higher in open canopy forest with a mean individual of 8.14 per 10 meters out of the 814 total individuals. The close canopy forest had only 4.57 mean individuals for the total of 457. Species level diversity was higher in open canopy forest (H’ = 1.957) compared with the closed canopy forest (H’ = 1.933). These results suggest that butterflies prefer open canopy forest or clearing for their plights. Butterfly spatial distribution was uneven in the dipterocarp forest of LUBG with only 6 species of aggregate assemblages and 98 species with random distribution.

Pastoralists’ Perceptions towards Rangeland Degradation and Management in Don...AI Publications
Local land users often have different perceptions on the problems of rangeland degradation, compared to researchers and Government officials. This study was aimed at breaching this gap, by empirically exploring pastoralists’ perceptions regarding rangeland degradation in Donga-mantung. The pastoralists’ perceptions were studied through a descriptive statistics method. Focus group discussions, field observations and structured/semi-structured survey questionnaires, were used for data collection, where 200 pastoralists were targeted. The study covered seven Ardorates based on intensity of rangeland degradation (high, medium and less). The major findings indicate that, the main livestock production constraints were Insufficient and poor pasture (50.5%), cattle diseases (24.5%), Farmer/grazer conflicts (14.5%) and insufficient cattle drinking points (10.5%). Majority of respondents (59.5 %) confirmed that cattle population is declining in the study area. According to 59.5% of the respondents, the study area present range condition has deteriorated and become poor. The major causes for degradation were overgrazing, bush encroachment, soil erosion and limited care and attention paid to rangelands. The major socio-economic impacts of rangeland degradation were poverty (51.0%), food insecurity (35.5%) and conflicts (11.0%). The pastoralists of the study area traditionally practice rangeland management in different ways such as bush burning, bush clearing and herd mobility. A proportion of them (41.5%) have adopted the planting of improved pasture(s). Government and NGOs’ supports proved to be limiting in the study area. Nevertheless, the measures perceived by pastoralists to reduce degradation of their rangeland include; planting of improved pastures (40.5%), clearance of bushes that have encroach on rangelands (28.5%), establishing community awareness and community empowerment on rangeland degradation (17.0%), reducing the number of farmlands (9.5%) and reducing soil erosion (4.5%). This study showed the need for rangeland professionals, researchers, planners and other stakeholders to integrate the communities’ perceptions and existing indigenous ecological knowledge to ensure a sustainable rangeland management.
A MODEL TO ESTIMATE STORED CARBON IN THE UPLAND FORESTS OF THE WANGGU WATERSHEDAsramid Yasin
Abstract
Climate change coupled with deforestation has brought about an increase in greenhouse gas emissions in the
atmosphere. One way to control climate change is to reduce greenhouse gas emissions by maintaining the integrity
of natural forests and increasing the density of tree populations. This research aimed to (a) identifies the density
of stand trees in the upland forests of the Wanggu Watershed; (b) analyze the potential carbon stocks contained in
the upstream forests of the Wanggu Watershed; (c) develop a model to estimate potential carbon stocks in the
upland forests of the Wanggu Watershed. The land cover classification in this study used the guided classification
with the Object-Based Image algorithm. Normalized Difference Vegetation Index (NDVI) was employed as an
indicator of vegetation cover density. Field measurements were carried out by calculating the diameter of the stand
trees in 30 observation plots. Field biomass values were obtained through allometric equations. Regression analysis
was conducted to determine the correlation between NDVI densities and field biomass. The results showed that
the best equation for estimating potential carbon stocks in the Wanggu Watershed forest area was y = 3.48 (Exp.
7,435x), with an R2 of 50.2%. Potential above ground biomass carbon in the Wanggu Watershed based on NDVI
values was 414,043.26 tons in 2019, consist of protected forest areas of 279,070.15 tons and production forests of
134,973.11 tons. While total above biomass carbon based on field measurement reached 529,541.01 tons, consist
of protected forests of 419,197.82 tons and production forests of 110,343.20 tons.
Autecology of Impatients parviflora DC. in natural forest communitiesEdytaSierka
Chmura D., Sierka E., Orczewska A. (2007). Autecology of Impatients parviflora DC. in natural forest communities. Botanika - Stecina 11, 17-21., 2007
In three neighbouring regions situated in southern Poland, differing in land use, soils, and type of forest vegetation, autecological studies on one of the most invasive alien species of the country, small balsam Impatients parviflora, were conducted. The habitat requirements of I. parviflora were estimated in 139 permanent plots, randomly distributed in various forest communities and varying in the abundance of the examined species. The forest stands were located either in nature reserves (Kraków-Częstochowa Uppland, Silesian Upland) or in old growth forests (Głubczyce Plateau). The physical and chemical properties of soiils (soil reaction, mineral and granulometric composition of substratum), litter depth, slope, and aspect were gathered and showed on ecodiagrams. The study shows that small balsam is a species with a wide ecological amplitude, what probably contributes to its invasiveness and enables success in colonizing and persisting in forest ground vegetation.
Valorization of shea caterpillar droppings (Cirina butyrospermi Vuillet) in t...Innspub Net
Works on park lands show that shea tree is a widespread species in the fields in Burkina Faso. There are caterpillars which are rich in proteins and throw out important quantity of dejection on the soil surface. The aim of this study was to determine the amount of droppings produced by caterpillars and their chemical quality in Koumbia area. The amount of dejection was determined on small plots and expressed as amount of dry matter (DM). Chemical analyzes have focused on the major elements (C, N, P and K). Our results show an average production of 19.34 kg for an average area of 68.47 m2 under a shea tree. We also observe that the production of caterpillar droppings is a function of the shea trees density and fluctuate between 440 and 3 775 kg ha-1. The data of chemical analyzes show that caterpillar droppings have high content of carbon (477.7 g kg-1) and nitrogen (10.8 g kg-1) and low content of phosphorus (0.3 g kg-1) and potassium (0.9 g kg-1). The amounts of C and N that caterpillar droppings are likely to bring, show that they can cover between 56 and 484 % of annual loss of soil C and fully compensate exports N of major crops (cotton, maize, sorghum) of the study area. The valorization of caterpillar droppings is therefore a way of ecological management of soil fertility of shea parks. However, the C/N (44) of caterpillar droppings suggests further agronomic investigations.

In these plots, abundance, DBH and heights of all woody species were recorded, and soil sample was collected 1m X1m from the four corners and center of each quadrant. General allometric model was used for estimating above and belowground biomass. The organic carbon content of the soil samples was determined in the laboratory. Finding: A total of 66 woody plant species belong to 42 families were identified, Fabaceae was the most dominant families. The total mean above and belowground carbon stock was 216.86 ton/ha and 114.71 ton/ha respectively and soil organic carbon (SOC) 103.15 ton/ha. Above and belowground carbon increased as altitude decreased, but SOC increases with increase of altitude. Originality/value: Carbon stock estimation in the forest helps to manage the forests sustainably from the ecological, economic and environmental points of view and opportunities for economic benefit through carbon trading to farmers.
Abstract— This study was conducted in Gunugo watershed at Wolayitta zone to assess the amount of some soil chemical properties affected by traditional agroforestry practices and along different elevation gradients. The dominant agroforestry practices (homegarden, parkland and woodlot), and three elevation gradients (upper, middle and lower) were used to collect soil samples. One composite sample was taken from each sampling point from each soil depths, under three agroforestry practices and three elevation gradient with three replications to have a total of 54 soil samples at 20 x 20 m plot. Then the selected soil chemical properties among agroforestry practices and along elevation gradient was determined at p<0.05. The EC, pH and CEC of the top soil was significantly higher on homegarden than parkland and woodlot while EC, pH and total nitrogen of the sub soil were significantly higher on homegarden than parkland and woodlot. Further, only the top soil EC and CEC were significantly higher on lower elevation than upper and middle elevation and there was no significant difference in sub soil chemical parameters among elevation levels. In relation to this, most of the soil chemical properties show as the study area is being degraded. Therefore, are recommended for sustainable soil chemical property management. Hence, homegarden is suggested as a better agroforestry practice for rehabilitation of the area in a sustainable manner through enhanced accumulation of total nitrogen, good EC and CEC at all elevation gradients.
Diversity and distribution of butterflies in the open and close canopy forest...Innspub Net
Butterflies were sampled in Cadaclan, San Fernando La Union Botanical Garden (LUBG) of North Luzon to provide information on species-level diversity trend and distribution of butterflies on the open and close canopy portion of the dipterocarp forest from 2012-2014 using field transect method Species accumulation curve shows that additional sampling is needed for the possible turnover of species. Butterfly abundance was higher in open canopy forest with a mean individual of 8.14 per 10 meters out of the 814 total individuals. The close canopy forest had only 4.57 mean individuals for the total of 457. Species level diversity was higher in open canopy forest (H’ = 1.957) compared with the closed canopy forest (H’ = 1.933). These results suggest that butterflies prefer open canopy forest or clearing for their plights. Butterfly spatial distribution was uneven in the dipterocarp forest of LUBG with only 6 species of aggregate assemblages and 98 species with random distribution.

Pastoralists’ Perceptions towards Rangeland Degradation and Management in Don...AI Publications
Local land users often have different perceptions on the problems of rangeland degradation, compared to researchers and Government officials. This study was aimed at breaching this gap, by empirically exploring pastoralists’ perceptions regarding rangeland degradation in Donga-mantung. The pastoralists’ perceptions were studied through a descriptive statistics method. Focus group discussions, field observations and structured/semi-structured survey questionnaires, were used for data collection, where 200 pastoralists were targeted. The study covered seven Ardorates based on intensity of rangeland degradation (high, medium and less). The major findings indicate that, the main livestock production constraints were Insufficient and poor pasture (50.5%), cattle diseases (24.5%), Farmer/grazer conflicts (14.5%) and insufficient cattle drinking points (10.5%). Majority of respondents (59.5 %) confirmed that cattle population is declining in the study area. According to 59.5% of the respondents, the study area present range condition has deteriorated and become poor. The major causes for degradation were overgrazing, bush encroachment, soil erosion and limited care and attention paid to rangelands. The major socio-economic impacts of rangeland degradation were poverty (51.0%), food insecurity (35.5%) and conflicts (11.0%). The pastoralists of the study area traditionally practice rangeland management in different ways such as bush burning, bush clearing and herd mobility. A proportion of them (41.5%) have adopted the planting of improved pasture(s). Government and NGOs’ supports proved to be limiting in the study area. Nevertheless, the measures perceived by pastoralists to reduce degradation of their rangeland include; planting of improved pastures (40.5%), clearance of bushes that have encroach on rangelands (28.5%), establishing community awareness and community empowerment on rangeland degradation (17.0%), reducing the number of farmlands (9.5%) and reducing soil erosion (4.5%). This study showed the need for rangeland professionals, researchers, planners and other stakeholders to integrate the communities’ perceptions and existing indigenous ecological knowledge to ensure a sustainable rangeland management.
A MODEL TO ESTIMATE STORED CARBON IN THE UPLAND FORESTS OF THE WANGGU WATERSHEDAsramid Yasin
Abstract
Climate change coupled with deforestation has brought about an increase in greenhouse gas emissions in the
atmosphere. One way to control climate change is to reduce greenhouse gas emissions by maintaining the integrity
of natural forests and increasing the density of tree populations. This research aimed to (a) identifies the density
of stand trees in the upland forests of the Wanggu Watershed; (b) analyze the potential carbon stocks contained in
the upstream forests of the Wanggu Watershed; (c) develop a model to estimate potential carbon stocks in the
upland forests of the Wanggu Watershed. The land cover classification in this study used the guided classification
with the Object-Based Image algorithm. Normalized Difference Vegetation Index (NDVI) was employed as an
indicator of vegetation cover density. Field measurements were carried out by calculating the diameter of the stand
trees in 30 observation plots. Field biomass values were obtained through allometric equations. Regression analysis
was conducted to determine the correlation between NDVI densities and field biomass. The results showed that
the best equation for estimating potential carbon stocks in the Wanggu Watershed forest area was y = 3.48 (Exp.
7,435x), with an R2 of 50.2%. Potential above ground biomass carbon in the Wanggu Watershed based on NDVI
values was 414,043.26 tons in 2019, consist of protected forest areas of 279,070.15 tons and production forests of
134,973.11 tons. While total above biomass carbon based on field measurement reached 529,541.01 tons, consist
of protected forests of 419,197.82 tons and production forests of 110,343.20 tons.
Autecology of Impatients parviflora DC. in natural forest communitiesEdytaSierka
Chmura D., Sierka E., Orczewska A. (2007). Autecology of Impatients parviflora DC. in natural forest communities. Botanika - Stecina 11, 17-21., 2007
In three neighbouring regions situated in southern Poland, differing in land use, soils, and type of forest vegetation, autecological studies on one of the most invasive alien species of the country, small balsam Impatients parviflora, were conducted. The habitat requirements of I. parviflora were estimated in 139 permanent plots, randomly distributed in various forest communities and varying in the abundance of the examined species. The forest stands were located either in nature reserves (Kraków-Częstochowa Uppland, Silesian Upland) or in old growth forests (Głubczyce Plateau). The physical and chemical properties of soiils (soil reaction, mineral and granulometric composition of substratum), litter depth, slope, and aspect were gathered and showed on ecodiagrams. The study shows that small balsam is a species with a wide ecological amplitude, what probably contributes to its invasiveness and enables success in colonizing and persisting in forest ground vegetation.
Valorization of shea caterpillar droppings (Cirina butyrospermi Vuillet) in t...Innspub Net
Works on park lands show that shea tree is a widespread species in the fields in Burkina Faso. There are caterpillars which are rich in proteins and throw out important quantity of dejection on the soil surface. The aim of this study was to determine the amount of droppings produced by caterpillars and their chemical quality in Koumbia area. The amount of dejection was determined on small plots and expressed as amount of dry matter (DM). Chemical analyzes have focused on the major elements (C, N, P and K). Our results show an average production of 19.34 kg for an average area of 68.47 m2 under a shea tree. We also observe that the production of caterpillar droppings is a function of the shea trees density and fluctuate between 440 and 3 775 kg ha-1. The data of chemical analyzes show that caterpillar droppings have high content of carbon (477.7 g kg-1) and nitrogen (10.8 g kg-1) and low content of phosphorus (0.3 g kg-1) and potassium (0.9 g kg-1). The amounts of C and N that caterpillar droppings are likely to bring, show that they can cover between 56 and 484 % of annual loss of soil C and fully compensate exports N of major crops (cotton, maize, sorghum) of the study area. The valorization of caterpillar droppings is therefore a way of ecological management of soil fertility of shea parks. However, the C/N (44) of caterpillar droppings suggests further agronomic investigations.

In the Spring Semester the Interior Design Sophomore Studio , College of Human Ecology , East Carolina University took on the challenge of designing houses that are sustainable and more varied than plans that might have been generated to date. This is in keeping with the University's committment to be a leader in engaged scholarship as well as community service. The students were excited that their work would be put to use. So what we offer here are 18 new plans for Habitat Houses that can be used by anyone who might profit from the student work.
Each house has an imaginary family that the student designers kept in mind in view of the design profession that they will soon join is a service profession: there will be clients for all of the projects that these students will design as practicing interior designers. While these families are fictional , essentially placemarkers in the process of learning to design for others you are welcome to substitute your family, friends or members of the community for the prototype client and use the organizational or program drawings, the plans, elevations and sections and scchedules to extend the student work. We are at the end of our semester so we dedicate our efforts to your use.

The objective of this study is to characterize the current status of woody species in agrosystems and to identify ecologically important woody species that favor agriculture-livestock integration in the context of strong anthropic pressures in the Maradi region. The ground forest inventory method was used to characterize woody vegetation in three sites in the departments of Dakoro (north), Guidan Roumdji (center) and Madarounfa (south). A total of 187 plots were installed, each with a surface area of 2500m². Data collected included species list, total height, diameter at 1.30m from the ground and both perpendicular diameters of the crown, and natural regeneration of woody species. The results show that the southern zone has more species (17) divided into 9 families, followed by the central zone with 16 species and 12 families and finally the northern zone with 9 species and 7 families. The diversity decreases from the south (3.01 bites), center (2.27) and north (1.76 bites). As for the dendrometric parameters, the difference is significant (P ˂ 0.000) with greater values of average height, diameter at 1.30 m from the ground and basal area of the trees in the southern area. It is not significant between ecological zones the basal area of trees (P = 0.9). Faidherbia albida and Piliostigma reticulatum were the most ecologically important species distributed in all three zones. The overall diameter class and height structure imputed by the dominant species shows a negative skewed distribution of the disturbed stand in all three ecological zones. Regeneration is 747±65 (ft/ha), 2136±177 (ft/ha), and 1018±63 (ft/ha) in the north, center, and south, respectively, with a highly significant difference (P=0.000). This regeneration is an important source for re-greening the fields if maintained. This study provides important results that can be used to refine the management of agroforestry parks for various ecosystem services for the benefit of populations.
Species and Community Diversity of Vascular Flora along Environmental Gradien...Shujaul Mulk Khan
Quantitative and qualitative characteristics of floristic diversity at species level along environmental gradients were measured using a randomly stratified design for identifying major plant communities of Narran Valley, Pakistan. Data was collected at 144 sampling stations along 24 altitudinal transects, 12 each at southern and northern aspects. Altitudinal range transects was within the limits of 2450 to 4100 masl. Some 198 species belonging to 68 families were indentified along transects. The Two Way Cluster Analysis (TWCA) and Indicator Species Analysis (ISA) recognized 5 plant communities with significant indicator species. The communities generally showed an elevation-latitudinal gradient complex from inclined, mesic-cool temperate vegetation of Phenerophytes and Chamaephytes, to more dry cold subalpine and alpine herbaceous vegetation of Cryptophytes and Therophytes. ISA analysis revealed that the mountain aspect, altitude from the sea level and soil depth were the strongest environmental variables (p ≤ 0.05) for determining the community structure. Species diversity was optimum at the middle altitudes (2800-3400 masl) as compared to either the lower or higher altitudes. Herbaceous vegetation had positive correlation with altitude as a function of eco-physiological pressures as generally observed on like other highly elevated peaks Himalayas.

Acta Phytopathologica et Entomologica Hungarica, 2008
At the end of the prosperity of the coal mining industry in Upper Silesia in Poland, new habitats were created in disturbed areas which, in the case of flooded mine subsidence, led to the formation of a type of ecological niche not encountered before. In the present work the authors describe the diversity of oak-hornbeam forest in the areas of flooded mine subsidence and the thrips communities connected with them. In 2006 and 2007, the thrips fauna of subsidence areas was sampled in biotopes directly associated with depressions (waterside, contact zones between aquatic and terrestrial-forest biotopes). In both ecosystems a total of 118 plant species and 56 thrips species were found. Disturbance of land resulting in flooded mine subsidence contributes to increased species diversity of both plants and thrips. Other kinds of disturbance such as traffic routes and its direct and indirect impact cause reduce numbers of plants and thrips species.

This study quantified the effect of environmental variables on plant species composition in the Peochar Valley, located in the Hindu Raj mountains of the Hindu Kush. A mixture of quadrat and transect methods were used. Quadrat sizes were 10 × 10 m, 2 × 5 m, and 1 m2 for trees, shrubs, and herbs, respectively, determined using the minimal area method. Twenty-seven stations were established along 6 elevation transects on slopes with various aspects. Density, cover, and frequency were recorded for all species in each quadrat. Aspect, elevation, rock types, soil nature, and grazing pressure were also considered as edaphic and topographic variables. Preliminary results showed that the Peochar Valley hosts 120 species. Presence/absence data for these species were analyzed with cluster and 2-way cluster techniques to elaborate species composition in the study area; this resulted in 4 plant communities. Species abundance and environmental data matrices were developed to evaluate the ecological gradient of vegetation through canonical correspondence analysis. Of the environmental variables, elevation, aspect, grazing pressure, soil depth, and rock type showed a significant effect on species composition and diversity. We also identified the dominant and rare plant species in each plant community based on their low importance value indexes. Conservation measures are recommended for all flora of this valley and for rare species in particular.
ANTHROPOGENIC INFLUENCES ON THE NATURAL ECOSYSTEM OF THE NARAN VALLEY IN THE ...Shujaul Mulk Khan
People derive many essential goods from plant resources, including food, medicines and fodder. However, the link between biodiversity and ecosystem services and their role in the support of human well-being is often poorly understood. Mountain ecosystems support a high biological diversity including rare and endangered plant species. They also provide a home to some 12% of the world's human population, who use their traditional ecological knowledge to utilise local natural resources. The Himalayas are the world's youngest and largest mountain range that supports a high plant biodiversity and hence provides many ecosystem services. Due to remote location, harsh climate, rough terrain and topography, many areas in the Himalayas have been still poorly known for their vegetation ecosystem services. The people in the Naran Valley, in the western Himalayas, depend upon local plant resources for a range of services and goods, from grazing for livestock to use of medicinal plants. During this study abundance and uses of each species were computed using computational ecology; principal components analysis (PCA) and response curves (RC) using CANOCO. The analyses showed an increasing trend of grazing, but with a decrease in fodder availability, with altitude increase in the valley. The assessment of such ecosystem services may assist in developing conservation strategies, especially for endangered mountain ecosystems.

Fragmentation leads to the formation of edges between habitats, which in
turn changes biotic and abiotic factors that might influence herbivory or
plant-herbivory interactions. The aims of this study were to describe the
herbivory community associated with oak (Quercus) and to determine the
effects of proximity to a Eucalyptus edge and season on insect herbivory.
We selected three forest sites that were subsequently divided into three
quadrants located at different distances from the Eucalyptus edge: edge
(0 m), intermediate (30 m), and oak forest interior (60 m). We randomly
selected 10 oak trees per quadrant and conducted monthly surveys, during
the dry and rainy season (from February to October 2010), where we
quantified leaf area and the percentage of herbivory. These were analyzed
using linear mixed models, with distance and season as fixed factors and
individual and site as random factors. The primary oak herbivores were
Lepidoptera caterpillars. We found that herbivory increased away from
the edge but just during the rainy season, although higher herbivory levels
were found during the dry season. These results seem to be related to a
specialist community of herbivorous associated to the Quercus. This study
emphasizes the importance of considering border effect, especially within
Natural Protected Areas to establish strategies to improve and maintain
native oak forest and the biodiversity of its Lepidoptera herbivorous
community.
Introduction
Landscape modification due to anthropogenic activities (e.g.,
land conversion to agricultural or livestock) has resulted in
habitat fragmentation, one of the major threats for forest
conservation (Buckley 2000, Franklin et al 2002).
Fragmentation is defined as the disruption or breakdown of
large vegetation patches into smaller ones resulting in a dis-
continuity of resource distribution that affects species occu-
pancy, reproduction, and/or survival (Franklin et al 2002).
One of the important features of this phenomenon is an
increase in edge length relative to the forest area, particular-
ly in small habitat fragments (Laurance 1991, Laurance &
Yensen 1991, Murcia 1995, Laurance et al 2007, De

Bacteria and Fungi Population of Surface Soils under Various Land Use Types i...BRNSS Publication Hub
The study was carried out at the Teaching and Research Farm of the School of Agriculture and Agricultural
Technology, Minna, in the month of July 2014. The aim of the study was to estimate the bacteria and
fungi population of three selected vegetation types at three soil depths and correlate microbial counts
with the physicochemical properties of soils. The experiment was a 3 by 3 factorial experiment, arranged
in a completely randomized design. The treatments were vegetation types (fallow, gmelina, and teak)
and three soil depths (0–5 cm, 5–10 cm, and 10–15 cm). Data obtained were subjected to ANOVA while
means were separated using the Student–Newman–Keuls test Linear relationship. The standard pour
plate method was used to estimate bacteria and fungi colony-forming units (CFU) in 1 g soil. Physical
and chemical analyses were carried out by standard laboratory methods. The bacterial and fungal counts
were highest in the gmelina vegetation and least under teak. The 0–5 cm soil depth had the highest
microbial counts. Bacterial population correlated positively and significantly with the fungal population
and organic content while microbial population correlated negatively with soil pH. Gmelina vegetation
produced the highest microbial population followed by fallow and teak in that sequence. Fallow
recorded the narrowest C/N and C/P ratios, respectively, implying N mineralization and P solubilization
while the tree vegetations recorded wider ratios signifying N and P immobilization. It can, therefore, be
inferred from the results obtained that tree vegetations can be under cultivation with much sacrifice in
inorganic N and P fertilizers. Fallow land, on the other hand, will require lower inorganic N and P inputs
and, therefore, has prospects in reduction of environmental pollution and subsequent increase in crop
production.
The Role of Soil Organisms and Functions in different Coconut based Multiple ...Agriculture Journal IJOEAR
Abstract—Sampling was done in wet and intermediate zones represented by the Walpita and Makandura research centers, respectively. Eleven land use systems were considered for the study; coconut mono culture (CM), bare land (BL) and coconut multiple cropping. Under coconut multiple cropping, nine different intercrops were selected separately for each zones. The treatments were arranged in a randomized complete block design (RCBD) with three replicates (n = 3). The experiment was conducted under mature baring coconut (>20 years) plantation. Soil Macrofauna was sampled using one transect with three replicates at each land use type using quadrate size (30×30cm) from 0-30 cm depth and visible organisms were handpicked and preserved in 75% alcohol. Dilute plate technique and Spread plate technique was used to determine the soil micro organisms’ density. Those techniques were used to cultivate the fungi and bacteria under 〖10〗^(-2) and 〖10〗^(-5) dilution level respectively.
Research identified 12 classes (Crusteacea, Oligochaeta, Hirudinea, Gastropoda, Acarina, Araneida, Scopionida, Chilapoda, Diplopoda, Amphibia, Reptelia) and 14 orders (Hemiptera, Diptera, Coleoptera, Thysanura, Hymenoptera, Lepidotera, Orthoptera, Blattaria, Mantodea, Phasmida, Dermaptera, Isoptera, Siphonaptera, Thysanoptera) of soil organisms. Class insecta shows the high diversity with 14 orders. Colony forming unit (CFU) value of bacteria was higher than that of the fungi value. Findings of intermediate and wet zones’ studies suggested that coconut multiple cropping systems may have high diversity, abundance and functional role of soil organisms. Both zones studies suggested that coconut multiple cropping systems may increase soil moisture factor, respiration rate, biomass carbon content, organic carbon percentage, total nitrogen content, organic matter content and C:N ratio in 0-30cm depth other than the coconut monoculture systems. Overall data of two different zones indicated a significant positive correlation of soil organism diversity, abundance and their functional role with cropping systems. Those data can be used as a reliable basic bio indicator for payments for ecosystem services (PES). It supports to valorize the economic value of the ecological services returned by soil organisms.

Abstract
A research was conducted in Kafta-Humera districts of the Northern Ethiopia with the objective to determine the
effect of human settlement on rangeland wood species productivity and biodiversity under three altitudinal
ranges (600-1000, >1000-1400 and >1400-1800 m.a.s.l.) and along three distance intervals near (0-2 km),
middle (2-4 km) and far (4-6 km) from settlement. The Statistical Package for Social Sciences (SPSS, version
16.0, 2013) was used to analyze the soil and vegetation data. In the study districts, a total of 46 woody species
were identified. Browse biomass of woody species in the low, middle and upper altitude categories were, 180.47,
225.97 and 243.72 kg ha-1, respectively. Browse biomass of woody species near, middle and far distance from
settlement were, 145.30, 228.03 and 276.824 kg ha-1 respectively. Woody species diversity was increased with
increasing altitude, and was significantly lower near to settlement than middle and far distance. Far distance
from settlement had significantly higher in organic carbon, available phosphorus and available potassium than
middle and near distance from settlement. The upper altitude had significantly higher organic carbon, organic
matter, available phosphorus and available potassium than the lower and middle altitude. In conclusion, the
study area was highly dominated by the thorny shrubs woody species. This implies that there is undergoing
reduction biodiversity and productivity degradation. Therefore, appropriate plan of biodiversity conservation
such as establishing, designing and implementations of watershed management for physical and biological
conservation should be planned to minimize loss of biodiversity.
Keywords: Settlement, plant Species composition, plant species abundance, plant Species diversity, biomass

1. Introduction
Plant species are highly damage due to high animal grazing pressure and human activities around human
settlement areas (Brinkmann, 2009). Settlement influence the composition and abundance of woody plant
species, patterns of soil nutrient redistribution and finally, these patterns influence the productivity and diversity
of pastoral systems (Jefferey, 2007).
In Kafta - Humera satellite imagery in 2000 (before resettlement) and 2007 (after resettlement) was taken
to know the degree of change in land use and cover related to settlement. The results of the spatio-temporal
analysis showed decreased in woodland by 25.8% and an increased in arable land by 21.8%, and in 2011 after
ten years arable land increased almost by 100%, woody vegetation cover reduced by 42% (Moti et al., 2011).
Settlements in Ethiopia have been studied widely. Though, most the studies have been focused more on
the social and economic outcomes, planning and implementation (Pankhurst, 2005; Hammond, 2008). There has
been rather not enough research undertaking at present time, to address some of the fundamental problems with
the effect of human settlement on rangeland woody diversity, productivity and soil characteristics (Gebrehaweria,
2011; Moti et al., 2011).
Therefore this study was conducted with a general objective of determining the effect of human settlement
on rangeland wood species productivity and biodiversity as well as soil characteristics in Kafta-Humera, in
northern Ethiopia. And the specific objectives were:
• To determine the effect of human settlement on woody species composition, plant abundance and
species diversity under three altitudinal range and distance away from human settlement in Kafta-
Humera district of northern Ethiopia; and
• To investigate the effect of human settlement on rangeland woody biomass production and soil
characteristics under three altitudinal ranges and distance away from human settlement in Kafta-
Humera district of northern Ethiopia;

(Figure 1).
Figure 1: Location of Kafta-Humera, the study area
The District is located between 13040’and 14027’N, and 36027’and 37032’E. It covers an area of 160650 ha and
its altitude ranges from 560 to 1849 m.a.s.l. The mean maximum temperature varied from 41.70C - 330C while
the mean minimum temperature varied from 22.20C - 17.50C. The rainfall ranges from 448.8 -1102.5 mm
(Hailesilassie, 1998; EARO, 2002).
2.2 Methods of Data Collection
Vegetation data were collected in a random sample area of 50 m x 50 m at each distance from settlements with in
each altitude. Twelve quadrats were random taken at each distances, totaling 108 = (3 attitudes x 3 distances x 12
quadrats). Three composite soil samples in each distance from settlements under each altitudinal ranges were
pooled and yielding a total of 27 soil samples.
2.3 Statistical Analysis
Ordination of sampling sites under the three altitude and three distances from settlements was done by
multivariate techniques, using Conoco (Ter Braak, 1997). Ordination of woody species was done by a Principal
Component Analysis (PCA). In addition, the correlations of soil parameters with the woody species were done
using a Redundancy Analysis (RDA).
Woody species composition similarity among distance from settlements was estimated by the model
Jaccard coefficient of similarity according to Krebs (1998). Biomass of selected browse woody species was
estimated using the model of Petmak (1983). The diversity indices for woody species, plant abundance of each
species and species evenness data were estimated using PAST software (Koleff et al., 2003).
To test differences in woody species diversity, plant abundance, soil characteristics and biomass production,
a General Linear Model (GLM) was applied using SPSS software (version.16). Moreover, Jaccard coefficient of
similarity (Magurran, 2004) was used to test the differences on species compositions similarities along altitudinal
range and distance from settlement. Tukey multiple comparison was used to test significant differences among
the means.
Soil analyses were done in Mekelle, Ethiopia Agricultural Research Center for organic carbon (OC),
organic matter (OM), total nitrogen percentage (TN %), available potassium (K), available phosphorus (P), pH
and percentage of soil textures (clay, silt and sand).
3. Results and discussion
3.1 Woody species composition
In the study area a total of 46 woody species have been identified. In the lower altitude of the study area, a total
of 27 woody species were identified. Acacia mellifera, Adonsonia digitata, Boswellia papyrifera,
Dichrostachyus cinerea, Grewia bicolor and Termmalia brownii were the most dominant woody species for all
distance. In the middle altitude, Acacia bussei, A. mellifera, D. cinerea, ziziphus abyssinica and Ziziphus spina-christi
were the top five dominant encountered woody species for all distance. A. bussei, Carissa edulis, D.

cinerea, Dovyalis abyssinica, Maytenus senegalensis and Senna singueana were also common to the upper
altitudes for all distance intervals (Table 1).
The ordination result showed a clear separation of the 9 sites for the woody species, as the distance
interval from settlement in each altitudinal ranges are clustered separately (Figure 2a). The first and the second
ordination axis explained cumulatively 98% of the total variance extracted by the PCA. The result of the
sampling site x soil parameter using RDA showed higher relationships with woody species on the first and
second ordination axis with a correlation coefficient of 0.998 and 0.993, respectively. The first and second
ordination axis explained 95.5% for the total cumulative variance of woody species to soil relation extracted by
the RDA (Figure 2b).

filled squares = high altitude) in Kafta-Humera, Northern Ethiopia.
In the lower and middle altitude, A. mellifera and D. cinerea were the most dominant woody species near to the
settlements. A. bussei, D. cinerea, D. abyssinica and M. senegalensis were the common woody species to the
upper altitude near to the settlement (Table 1). Most of the dominant woody species in the study area were
thorny woody species and comparatively their relative abundance was higher than of the other woody species.
They can, therefore, be considered as the best indicators of intensively degraded rangelands of the area. This
finding was in agreement with the study of Moti et al. (2011).

3.2.2 The effect of altitude on browse woody species biomass
In all altitude, browse biomass were significantly increased with increased altitude (Table 2; F2,99 = 11.97, P <
0.000). Browse biomass of woody species in the low, middle and upper altitude were, 180.47, 225.97 and 243.72
kg ha-1, respectively (Table 2).
3.2.3 The effect of distance on browse species biomass
Browse biomass of woody species were significantly increased with distance increased from settlement (Table 2;
F2,99 = 49.70, P < 0.000). Browse biomass of woody species near, middle and far distance from settlement were,
145.30, 228.03 and 276.824 kg ha-1, respectively (Table 2). This result could be related to the decreasing of
browsing intensity animals and human activities with increasing distance from settlement.

3.4. Soil Parameters
3.4.1. The effect of altitudinal and distance on soil Parameters
3.4.1.1. The effect of distance on soil Parameters at different altitudinal ranges.
In the low altitude range, far distance interval was significantly higher in percentage of organic carbon and
organic matter as well as available phosphorus and the percents of sand contents than near distance to settlement.
In the middle altitude percentage of organic carbon and organic matter of soil were significantly lower in near
distance than far distance from settlement. In the upper altitude, percentage of organic carbon and organic matter,
available of phosphorus and available potassium of soil contents were recorded significantly higher in the far
distance from settlement than near and middle distance from settlement (Table 4).
3.4.1.2. The effect of altitude on soil Parameters
Sand soil content had showed significant decreased with altitude increasing (Table 4; F2,18 = 33. 07, P < 0.000).
Whereas, clay soil content was increased with altitude increasing (Table 4; F2,18 = 52.33, P < 0.000). In the lower
altitude, pH value was recorded significantly higher than upper and lower altitudes (Table 4; F2,18 = 6.16, P <
0.009). This is related to the fact that the pH value and sand soil increase with altitude decreases but clay soil
content increase with altitude increase Abreha et al., (2012). The higher sand content and pH value under lower
altitude is probably caused by increasing run off and soil erosion, and soil compacted. Nitrogen percentage under
low altitude was significantly difference from other altitudes. Under the upper altitude, organic carbon, organic
matter, available phosphorus and available potassium had significant higher as compared to other two altitude
ranges (Table 4). This is supported by the finding of Getachew et al., (2007) in Borana rangelands, Ethiopia and
Abreha et al., (2012) in Tsegede Highlands, Northern Ethiopia. This results probably due to the availability of
organic matter, higher standing biomass, soil moister and rainfall increasing with altitude range increasing.
3.4.1.3.The effect of distance on soil Parameters
In near distance to settlement, sand soil content had showed significantly higher than far distance from
settlement (Table 4; F2,18 = 3.65, P < 0.047). This result may be related to the high degree of soil erosion, high
grazing pressures and human activities near to settlement than far distance from settlement. Organic matter and
organic carbon had significant increased with distance increased from settlement. In far distance from settlement,
available phosphorus and potassium were recorded significantly higher than that of the near and middle distance
from settlement. Nitrogen Percentage had significantly higher in far distance from settlement than middle
distances from settlement (Table 4; F2,18 = 4.97, P < 0.019).

4. CONCLUSION
In the study districts, a total of 46 species of woody species were identified. A. bussei, A. mellifera, Anogeissus
leiocarpa, Combretum hartmannianum, D. cinerea, Lannea frutcosa and Z. spina-christi were the common
dominant species for all altitude and distance. In all altitude, woody species diversity and abundance in far
distance to settlements were significantly higher than near distance. In the lower altitude, all woody diversity
parameters had significantly lower. Sand and pH value had also significantly higher but soil clay was
significantly lower as compared to the middle and upper altitudinal ranges. Far distance from settlement had
significantly higher in organic carbon, organic matter, available phosphorus and available potassium than to
middle and near distance. The upper altitude had showed significantly higher in organic carbon, organic matter,
available phosphorus and available potassium as compared to the lower and middle altitude. Under the present
soil status, biodiversity and productivity circumstances of the areas near to settlement and middle distance
intervals from settlement, preservation or return of habitats should be of greater concern because the best way to
minimize biodiversity loss is to maintain the integrity of ecosystem function. Research related to rehabilitation
and possible restoration strategies through soil seed bank under various altitudinal ranges and settlement areas
should be considered.
