Wetland values, functions & facts

Wetland values, functions & facts

Wetlands provide important fish, wildlife & plant habitats
  • 43% of the federally listed species (Endangered Species Act) rely directly, or indirectly, on wetlands for their survival.
  • Wetlands are "biological supermarkets" that produce huge quantities of food.
  • They support a wide range of organisms from aquatic invertebrates to fish, birds, reptiles, and mammals.
  • Wetlands are used as breeding and egg deposition areas.
Wetlands improve water quality by:
  • intercepting surface runoff.
  • removing or retaining inorganic nutrients, such as nitrogen or phosphorus.
  • processing organic wastes.
  • reducing suspended sediments.
  • helping reduce environmental problems such as algal blooms, dead zones, and fish kills, that are generally associated with excess nutrients.
Wetlands enhance hydrologic cycle roles
  • Wetlands receive, store, and release water in numerous ways.
  • They help maintain stream flow in some areas.
  • Some wetlands replenish groundwater.
Provide natural flood control
  • Wetlands store and slowly release surface water.
  • Wetland vegetation impedes the movement of flood water.
  • Wetlands reduce erosion downstream and on adjacent lands.
Economic Benefits
  • 3 million migratory bird hunters generated $1.3 billion in retail sales.
  • Fishing and shellfishing industries harvest wetland-dependent species worth over $15 billion dollars a year.
  • Some medicines are produced from wetland soils and plants.
  • Blueberries, cranberries, mints, and wild rice are produced in wetlands.

Did you know?
  • The Salem/Keizer area has 1,432 acres of wetlands.
  • One acre of wetlands can store 1 to 1½ million gallons of water.
  • 75% of commercially harvested fish are wetland dependant. Add shellfish and that number jumps to 95%.
  • More than one-third of the nation's threatened & endangered species live only in wetlands.
