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.
