THE WETLANDS      

Wetlands are formed when water saturates an area for at least part of a year.

Wetlands store and slowly release water which reduces flooding and erosion throughout the watershed. Groundwater is recharged as water gradually percolates through the wetlands soils. Imagine the flow changes in the Knik Valley if there were no wetlands to absorb rain, flood surges and glacial and snow melt. These groundwater reserves are important to all species.

Wetlands also act as a contaminant filter trapping pollutants and improving water quality.

Wetlands provide breeding, rearing and feeding areas for mammals, waterfowl, raptors, songbirds, fish and aquatic invertebrates.
