Bringing Life to Streams
Removing Barriers to Migrating Fish
Since 1991, NSEA has worked to remove migratory barriers to fish by fixing broken culverts or replacing culverts with bridges (see below). This work has resulted in the opening of over 50 miles of upstream habitat for young fish and spawning adults.
STREAM BANK RESTORATION
The planting of native trees and shrubs along stream banks restores function in the riparian zone. This work improves salmon habitat by shading the stream (keeping water temperatures cool) and limiting erosion (keeping the water clear).
Even more, a well intact riparian zone:
Provides adequate habitat for salmon and other wildlife.
Contributes to consistent stream flows throughout the year.
Buffers against high flood flows and low summer flows.
Helps to filter pollutants.
In-stream salmon habitat improvement projects include adding massive root wads, whole tree trunks, gravel, and other features to create crucial salmon rearing and spawning habitat.
NSEA's connects resources and people together for the common good. Even small sections of improved streams, amid otherwise degraded habitat, can immediately provide an island of habitat for salmon.
