Wetland
Explanation:
- Wetlands are important features in the landscape that provide numerous beneficial services for people and for fish and wildlife
- Some of these services, or functions, include protecting and improving water quality, providing fish and wildlife habitats, storing floodwaters and maintaining surface water flow during dry periods
- Tropical wetlands assume important functions in the landscape and contribute considerably to the welfare of large parts of the human population, but they are seriously threatened because they are considered free resources of land and water
- Wetlands' microbes, plants and wildlife are part of global cycles for water, nitrogen and sulfur
- A dam is removed upriver from a wetland causing the river to bring much more freshwater to the wetland,in that case wildlife shifts from predominantly terrestrial species and stream-dwelling fish to predominantly lake dwelling fish
- The stream bank is replaced by extensive and often unstable shoreline in which floodplain vegetation is eliminated
- In general, dams reduce the biophysical variability (in flow, temperature, and materials transport) characteristic of rivers, which in turn reduces the biodiversity of both in-stream flora and fauna
