Study Notes
Definition and Characteristics of Wetlands
- A wetland is an ecosystem that is flooded or saturated by water, either permanently or seasonally.
- Wetlands are characterized by oxygen-free anoxic processes, especially in the soils.
- The primary factor distinguishing wetlands from terrestrial land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to unique anoxic hydric soils.
Biodiversity and Ecosystem Functions
- Wetlands are among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species.
Assessment and Conservation of Wetlands
- Methods have been developed to assess wetland functions, ecological health, and general wetland condition in many regions of the world.
- These methods have contributed to wetland conservation by raising public awareness of the functions some wetlands provide.
Constructed Wetlands
- Constructed wetlands are designed and built to treat municipal and industrial wastewater as well as to divert stormwater runoff.
- Constructed wetlands may also play a role in water-sensitive urban design.
