Which type of forest are these? B D E C

Forest types, disturbance, succession 9/19/11

How are forests classified? Evergreen or Deciduous Coniferous or Broad-leafed Dry or Wet Tropical, Temperate or Boreal

What is a forest biome? Many similar ecosystems throughout the world. Individual  population  community  Ecosystem  Biome

What is an ecosystem? The nonliving (abiotic) and living (biotic) components of an environment working together. http://www.explorelearning.com/index.cfm?method=cResource.dspView&ResourceID=639

What is an ecological disturbance? an event that results in a sustained disruption of an ecosystem's structure and function.

What are examples of disturbances to forest ecosystems? Logging Urbanization Agriculture Overpopulation of a single species/hunting i.e. the deer population Invasive species Fire Flood

What is succession? “more-or-less predictable and orderly changes in the composition or structure of an ecological community.”

What is primary succession? Succession on an area that has never been occupied by a community.

What is secondary succession? Succession on an area which had its community removed (by disturbance).
