This document summarizes the silvicultural characteristics of three tree species found in temperate forests of Nepal: Pinus wallichiana (blue pine), Quercus semecarpifolia (khasru oak), and Taxus baccata (Himalayan yew). It describes the key characteristics of each species, including physical descriptions, natural distributions, tolerance to shade, drought, frost and fire, soil preferences, and ability to coppice or sucker. The document concludes that understanding the silvicultural needs of each species is essential for their successful regeneration in temperate forest management.
This presentation provides an overview of a field-based practical exercise that allows students in forestry, ecology and natural resources to develop their understanding of forest stand dynamics. The exercise involves measurement of key tree growth parameters in four even-aged, single-species plantation stands of different age but occupying sites with similar soil and environmental characteristics. The selected stands represent key stages in stand development, from establishment to rotation age for fibre production. In the field, students work in small teams to gather data from an equal number of plots within each stand. Tree parameters include top height, crown diameter, live crown ratio and diameter at breast height. In addition, information on stand density and understorey vegetation is collected. Plot size and number can be varied to suit the constraints of class size and available time, though circular plots of 100 m2 are recommended. In the classroom, data are pooled and analysis focuses on presenting tree and vegetation changes through time. The simplest way of interpreting the data is to prepare graphs and charts for each of the parameters, though more advanced statistical interpretations are possible. The project as outlined here can be modified to meet the needs of different groups, and has been successfully used in undergraduate teaching of silviculture and forest ecology, as well as in postgraduate courses in natural resources management.

An increasingly industrialized global economy, rapid population growth, land degradation, land use pattern and role of various human activities have led to dramatically increased the pressure on the natural resources such as the available land for sustaining the livelihoods, and with over exploitation and extraction of the natural resources the ecosystems are becoming unsustainable and fragile since last century. The forest and tree cover of India is 78.92 million ha, accounting
for 24.01 per cent of the geographical area. But due to biotic disturbances such as over-grazing, deforestation, shifting cultivation and etc. also effect on regeneration of tree species inside and out side of the forest area.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Outline of the Presentation
1.Introduction
2.Mehods of the Study
3.Discussion
4.Conclusion
3. Introduction
Silviculture is that branch of forestry which deals with
establishment, development, care and reproduction of
stands of timber(Toumey and Korstian).
Indian Forest and Forest Products
Terminology, published by the Forest Research Institute
and Colleges, Deharadun,defines silviculture as the art
and science of cultivating forest crops.
4. Silvicultural Characteristics
• These indicate under what conditions a species may
be exposed to grow well.
• They include its tolerance to shade; tolerance to
draught; tolerance to frost; its tolerance to damage by
fire and grazing.
• Other characteristics include types of soil on which
grow well and its ability to coppice, pollard or
produce root suckers.
5. Tree Species in Temperate Forest
Two Types of Temperate Forest are prevalent
(Jackson,1994).
1. Lower Temperate Forest
Altitude 2000-2700 meter in the west,1700-2400 meter in
the east.
• Forest of Quercus leucotripchophora and Quercus lanata
• Quercus floribunda forest
• Quercus lamellosa forest
• Lower temperate mixed broadleaved forest,with abundant
Lauraceae
• Pinus wallichiana forest
6. 2.Upper Temperate Forest
Occurs at altitudes from about 2700 meter in the west
and center and from 2400 to 2800m in the west.
• Quercus semecarpifolia forest
• Upper temperate mixed broadleaved forest: mixed in
composition including A. campbellii,A.sterculiaceum,
A.pectinatum, R.arboreum, Litsea, Lindera, Neolitsea,
Tsuga dumosa
• Rhododendron forest
• Upper temperate coniferous forest: main species
include Abies pindrow, Picea smithiana, Cedrus
deodara, Taxus baccata
7. Methods of the Study
This term paper is entirely based on secondary
source.
Different manuals, textbooks, publications and
websites have been consulted for its
preparation.
8. Discussion
• Following three species have been described of
species of temperate forest.
1. Gobre Salla (Pinus wallichiana)
2. Khasru (Quercus semecarpiflora)
3. Loth Salla( Taxus baccata)
9. Blue Pine (Pinus wallichiana)
• A large Tree
• Needles in bundles of five, dark-bluish green,11-18
cm long
• Cones ellipsoid, 10-15 cm long
• Seed with wing 1.5-3 cm long
• Naturally found in Nepal between 1800 and
3600m, and very occasionally to 4400m
(Jackson,1994).
• It is widely distributed in the midland zone,between
the foothillls and main Himalayan range, where at its
lower altitude,mixed with P.roxburghii.(generally
found on north-facing slopes.
10. Silvicultural Characteristics of Blue Pine
• Strong light demander.
• Frost hardy, it suffers from snow, the crowns break
and young trees develop curvature at the base.
• Seedling may suffer from the draught after the end of
monsoon and again in April and May.
• It is moderately resistant to fire,blue pine is less fire
resistant than chirpine
• It prefers well-drained,porous soil and will grow on
limestone soil.
• It is a non-coppicer.
• They are very easily damaged by browsing.
• It can tolerate the competition from shrub and weed
growth,but dense,matted grass is harmful to them.
11. Khasru (Quercus semecarpifolia)
• Leaves are elliptical or oblong, spinous teethed or entire.
• Flowers :male spikes-crowed, female spikes-short in
clusters of 3 or more
• Fruits are fleshy acron.
• Seed- a fleshy nut, which can be removed from cup
• Bark is dark grey, exfoliating in irregular woody scales.
• It grows between 1700 and 3800m but is commonest
between 2400 and 3000m, and is the highest altitude oak
in Nepal.
• It is dominant with Abies spectabilish and Betula
utilis,especially on south facing slopes,at above 3000m.
• It is absent from the very high rainfall areas.
12. Silvicultural Characteristics of Khasru
•
•
•
•
•
•
•
•
•
Strong light demander.
The seedlings are resistant to frost.
It is sensitive to fire.
It tolerates the wide range of soil types. It needs
moderately fertile soils.
Survival is on poor rocky ridges but growth is poor.
It coppices and pollards fairly well.
It is sensitive to browsing.
Khasru forests occur in regions of moderate rainfall.
It is slow growing species and difficult to raise in the
nursery.
13. Himalayan Yew (Taxus baccata)
• Evergreen tree
• Bark- thin, reddish-grey, peeling off in narrow strips.
• Leaves in two rows,1.5 to 2.8 cm by 2 mm, dark green
above, pale beneath.
• Seed surrounded by a red fleshy aril, looking like a
berry, about 7mm in diameter.
• It is found in Nepal between 2300 and 4400m, often as an
understorey tree.
• It is found associated with Picea smithiana,Tsuga
dumosa, Pinus wallichiana and Quercus semecarpifolia
,particularly at higher altitudes.
• Leaves and barks are a good source of taxol, which is used
against ovarian, lung,breast and other types of cancer.
14. Silvicultural Characteristics of Himalayan Yew
• Strongly shade tolerant, can grow and reproduce
under fairly dense shade.
• It is frost hardy.
• It is a fire tender because bark is so thin that fire is
fatal to the trees.
• It is usually in shady places under trees. It does not
thrive in areas where forests have been cleared.
• Himalayan yew is a non-coppicer.
15. Conclusion
• Pinus wallichiana, Quercus semecarpifolia and Taxus
baccata are common tree species in temperate forest
although they are not always strictly adhere to these
altitudinal limits.
• Silvicultural characteristics have indicated their tolerance
to shade, draught, frost and tolerance to damage by fire
and grazing.
• Other characteristics have included the types of soil on
which grow well and its ability to coppice, pollard or
produce root suckers.
• Knowledge of silvicultural characteristics is essential for
regeneration of that species.
