Savannas have continuous tall grasses between 0.9-1.8 meters high, with wet and dry seasons, mean monthly temperatures between 15-20 degrees Celsius, and annual precipitation between 700-1500 millimeters. Common large herbivores in savannas include buffalo, wildebeest, and zebras, while rhinos, giraffes, and elephants also inhabit savanna landscapes.
Oak savannas were once a widespread habitat across the Midwest, consisting of open areas with large oak trees and a diverse understory of grasses, flowers, and shrubs. Efforts are being made to restore oak savannas by first identifying locations of former savannas, removing invasive trees and brush, conducting prescribed burns, and annually monitoring and burning the land over 10-12 years while gradually reintroducing native plant species.
Land productivity is key to feed the world - grasslands as “protein pools”
Land degradation remains a global challenge and reducing/reversing land degradation is a development/research priority
Soil comes to the global agenda: sustainable intensification
Global Environmental Benefits - land degradation and soils are among the priority global benefits (GEF/UNCCD)
There is not enough data on the biomass and productivity of different savannas and grasslands given the wide range of climatic and soil conditions. Savanna soils are very deep and well-drained, containing a fragipan layer - a dense, brittle subsoil layer when moist and very hard when dry. The soils formed in fertile loamy sediments on high stream terraces and also contain red laterite soils where iron has rusted in the soil.

Female cheetahs live with their litters of about three cubs for one to two years, teaching them hunting skills through play as the cubs learn to hunt on their own. Male cheetahs live alone or in small groups. African elephants are the largest land animals and use their large ears to radiate heat, but still seek water to cool off. They suck up water with their trunks and spray it over themselves before coating with dust. Lions also live on the African savanna with elephants and cheetahs.
An ecosystem is an area containing rocks, soil, plants and animals. The document discusses three ecosystems: the savanna grassland, largest found in Africa; the coral reef, known as the "rainforest of the sea" and sensitive to water temperature; and the desert, with the largest hot desert being the Sahara, which receives little precipitation.
Pyrogeography of savanna fire intensity and severityDaniel Godwin
Fire intensity is considered an important component of our understanding of savannas. Fire intensity can be used to predict probability of top kill of woody stems, and thus can deterministically link fire to demographic bottlenecks observed in savanna woody species. However, our understanding of the spatial processes of fire intensity is limited: What tree neighborhood effects on fire intensity exist? How does intensity vary across woody cover gradients? Is fire intensity really the best metric for understanding impact of fire on savanna plant communities? My research hopes to expand on these topics while suggesting future directions for research and applications in fire management.
This document provides information about various animals that can be found in the African savanna ecosystem. It describes the physical characteristics and habitats of African sea eagles, elephants, wildebeest, giraffes, hyenas, rhinos, kudus, impalas, zebras, hippopotamuses, gazelles, lions, and tigers. Key details include size ranges, average weights, group behaviors, geographic distributions within Africa, habitats within the savanna, and other distinguishing physical attributes.
The savanna is used by pastoralists who rear grass-eating animals and move them to find grass, which is a sustainable practice. Farmers who try to farm more intensively by continually moving to new land and burning scrub to plant more crops can cause desertification over time as the soil loses nutrients and blows away, leaving the land useless. As a savanna farmer, life is difficult - crops get poorer as the soil degrades and there are worries that the land may turn to desert without options to support the family.
The document provides information about the Savanna biome. It describes the Savanna's location between the tropics, its hot and wet summers and mild winters. It also outlines the key abiotic factors like fire and soil, biotic factors such as large herbivores and carnivores, and ecological relationships including producers, primary and secondary consumers, and decomposers. It discusses threats to the Savanna like pollution and overhunting, and ideas for conservation.
The document discusses prairies, which are temperate grasslands located in the interior of North America that experience hot summers and cold winters. Prairies are home to various animals like antelope, badger, bison and coyote as well as plants such as red elm, snailseed and pawpaw. Over the last century, prairies have become endangered due to agriculture and urban development reducing prairie dog habitat, though Native Americans historically relied on prairies' resources for food and medicine.
The savannah biome is home to many diverse species. It is located between tropical rainforests and deserts. The savannah has a tropical climate with droughts and fires that species have adapted to. Lions are an iconic savannah species that hunt prey in their grassland habitat. Humans have impacted the savannah through farming, fires, overhunting and more. Efforts are being made to preserve the savannah biome through nature reserves and prohibiting harmful activities.
The document describes savannas, which are grasslands with scattered trees located in tropical and subtropical regions. Savannas have a hot, dry climate with two distinct seasons - a long dry season and a short rainy season. They are often found bordering rainforests in Africa, Australia, South America, India, and Southeast Asia. Savannas support diverse populations of animals adapted to their climate and vegetation, including meerkats, giraffes, kangaroos, and tigers. The trees and plants found in savannas, such as acacias, pines, and palms, have adaptations like deep roots and thick bark to withstand fires and seasonal drought. However, savannas
The savannas are located in Africa, South America, Australia and parts of India. Animals in the savanna have developed adaptations like cheek pockets in baboons to store food and razor sharp teeth to defend against predators. Savanna plants also have adaptations like the baobab tree storing water in its thick trunk to survive dry seasons. However, human activities like fires, agriculture and hunting are threatening savanna ecosystems.
The document discusses the savanna ecosystem and pressures on the Sahel region of Africa. It describes the distinct wet and dry seasons in savanna climates and how plants and animals adapt. It explains how the movement of the Intertropical Convergence Zone brings seasonal rains and how the Sahel is prone to desertification due to insufficient rainfall and overgrazing of grasslands.
Kenya is a popular tourist destination in East Africa despite being an LEDC. It has many natural attractions that draw visitors, like beaches, mountains, wildlife reserves, and opportunities for safari. Tourism provides economic benefits through foreign income and job creation, but also has social, environmental, and economic disadvantages if not properly managed. The solution is to develop "green tourism" that is environmentally sustainable and involves local communities.
Ecotourism has grown rapidly but definitions vary widely. It aims to involve travel to natural areas in a sustainable way that benefits the environment and local communities. However, in practice ecotourism faces many criticisms. Large-scale operations can degrade the environment and exploit local people rather than helping them. There is a lack of regulation allowing "greenwashing" where unsustainable practices are misleadingly marketed. Negative impacts on communities include displacement, threats to culture, and environmental damage. Better standards and limits on commercialization are needed to ensure ecotourism truly achieves its goals.
Retired travelers have a positive economic impact through spending but can also negatively impact local cultures. While retired tourists spend more on local goods and support the economy, their presence in large resorts can remove local culture from view. Additionally, retired tourists may need medical care during long visits, and are more vulnerable targets for crime due to factors like limited mobility or close-mindedness. Increased security procedures have also discouraged some potential travelers, especially families and athletes, by restricting previously allowed carry-on items. Other forms of public transportation pose high crime risks as well. Mexico and Florida tourist areas struggle with drug and petty crime issues that rise during peak seasons.
This document discusses the impacts of tourism from economic, socio-cultural, and environmental perspectives. It outlines both positive and negative impacts in each category. For example, economically tourism can result in job creation but also seasonal fluctuations. Socio-culturally, it can preserve cultural heritage but also lead to loss of authenticity. Environmentally, tourism can raise environmental awareness but also cause pollution, overcrowding, and damage natural habitats if not properly managed. The document also discusses various measures to mitigate tourism's negative impacts, like green initiatives in the hotel, transportation, and cities/towns sectors.
Tourism has both positive and negative environmental impacts. Negatively, it can deplete natural resources through overconsumption of water and land, produce various forms of pollution including air, water, noise and solid waste pollution, and degrade the environment through unsustainable construction practices. However, tourism also has the potential to positively impact the environment by raising environmental awareness and generating funds to support conservation efforts. Overall, uncontrolled tourism without proper management poses threats to many natural areas through overuse and degradation of resources.
There has been a global increase in tourism over the last 60 years due to factors like increased disposable income, more paid holidays, and cheaper travel. Popular destinations include cities, beaches, and mountain areas for their culture, recreation, and scenery. Tourism is important for many economies, but can negatively impact the environment if not managed properly. Ecotourism is an alternative that involves small-scale tourism to benefit local environments and communities in a sustainable way.
