agricultural or horticultural purposes. An invasive plant is one that is established‚ then expand and reproduce on their own (Forest Management). This means that they have the ability to compete with native species and other native plant communities. Non-native invasive species affect natural ecosystems negatively by completely taking over all other plants. This can unbalance the ecosystem and harm animals as well as nearby plants. They can also spread exotic diseases to other plant life. 46% of the federally

Within any community some species may become less abundant over some time interval‚ or they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession". Some specific examples of observable succession include: 1. The growth of hardwood trees

Evaluate the relative roles of natural succession and human activities in the creation of ecosystems within the British isles. (40 marks) An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystems can be changed by both human activity and natural succession. Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example‚ after a wildfire)‚ or even millions

A biosphere reserve is an area of land or water that is protected by law in order to support the conservation of ecosystems‚ as well as the sustainability of mankind’s impact on the environment. This means that each reserve aims to help scientists and the environmental community figure out how to protect the world’s plant and animal species while dealing with a growing population and its resource needs. These areas were created by the United Nations Educational‚ Scientific‚ and Cultural Organization

land animals and plants live in forests‚ and many cannot survive the deforestation that destroys their homes. Deforestation also drives climate change. Forest soils are moist‚ but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles‚ many former forest lands can quickly become barren deserts. Removing trees deprives the forest of portions of its canopy‚ which

We can use the forests more sustainable in four different ways if we will just think about it. If we as a whole would emphasize the economic value of a forest’s ecological services‚ protect our old-growth forest‚ harvest trees no faster than they can replenish‚ and use a more sustainable substitute resource (Miller Jr.‚ 2007).

called a food chain. Let us make this point more clearly by taking the example of a simple food chain operating in a grassland or forest. In a grassland or forest‚ there is a lot of grass (which are green plants). This grass is eaten up by animals like deer. And this deer is then consumed (eaten up) by a lion. This simple food chain operating in a grassland or forest can be represented as: Grass --> Deer -->Lion (Producer) (Herbivore) (Carnivore) This food chain tells us that grass is the starting

determined by its location. For example‚ northern coniferous forests exist in sub-arctic portions of North America and Asia‚ but further north‚ the conditions are simply too harsh and the season too brief for trees to grow. Instead of trees‚ the short vegetation of the tundra thrives in these areas. The same occurs with altitude‚ as trees give way to short alpine vegetation in high mountainous regions. A biome is composed of many ecosystems‚ which are smaller communities of plants and animals and their
