Wetlands: Sci 6.3

Land covered by water during some part of the year

Swamps: Shrubs and trees mostly

Marshes: Grasses, rushes, sedges

A type of rush A type of sedge

Bogs *NOT stream-fed *Water is from precipitation *Soil often acidic, water-logged *may be habitat for carnivorous plants

Wetlands are important! They help: 1.trap sediments, keeping lakes and streams clear

2. remove nutrients, slowing eutrophication

3. prevent flooding

4. Provide habitats for many animals

Sewage treatment Filters take out solids Chlorine/O 3 /UV kill bacteria
