1) What are some of the benefits of wetlands (list 3) a. They provide habitats for birds and aquatic and threatened species by providing breeding, nesting, and feeding. b. They perform the same function as kidneys do for our bodies, in that they filter and remove pollutants. As water passes through a wetland, some of the pollution that is dissolved or suspended in the water is trapped by the wetland plants and soils. Many of these pollutants, which would otherwise contaminate surface waters, are converted into food for aquatic organisms. c. Flood and storm control by the water absorption and storage capacity of wetlands. as temporary storage basins, lower flood crests, reduce erosion, and limit the destruction caused by severe floods. 2) What does T & E stand for with regards to ecosystems along a river system?T & E stands for threatened and endangered species. An “endangered” species is one that is in danger of extinction throughout all or a significant portion of its range. A “threatened” species is one that is likely to become endangered in the foreseeable future. 3) What act has slowed the destruction of wetlands?The primary federal legislation governing wetlands is Section 404 of the Clean Water Act (CWA), enacted in 1972. Since its inception, the Clean Water Act and its broad protections of wetlands have slowed the destruction of wetlands throughout the nation. 4) What are riparian wetlands and what are some local projects in the area?Riparian wetlands are found in low-lying regions adjacent to rivers and streams that are periodically subjected to overbank flooding. Riparian wetlands intercept surface and subsurface (groundwater) runoff from the upland regions of the wetland and thus function as buffers for the river systems. These wetlands also interact periodically with floodwaters originating from rivers and streams; these hydrologic interactions can have a significant effect on river water quality. The La Mancha...
