Bringing Life to Streams
400 Restoration Projects Since 1991!
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.
During 2015, NSEA
Completed 11 Salmon Habitat Enhancement Projects
Installed 14 Large Woody Debris (LWD) structures
Removed 6 migratory obstacles resulting in full access to 0.3 miles of habitat
Planted 6,644 trees and shrub seedlings along stream banks
Maintained 28 past riparian projects along more than 3.4 miles of stream bank
During 2016, NSEA
Completed 10 Salmon Habitat Enhancement Projects
Installed 14 Large Woody Debris Structures
Removed 3 fish barriers
Opened 1.6 miles of habitat
Maintained 28 previous restoration projects
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.
