Marine Shoreline Inventory Report March 2004 Green/Duwamish and Central Puget Sound Watershed Water Resource Inventory Area (WRIA) 9

Report Inventories Nearshore Habitat for Juvenile Salmon

This report inventories selected shoreline habitat features that support nearshore habitat for juvenile salmonids. The results are presented in part using high-resolution aerial photos with overlays that classify the types of habitat provided.

Also available upon request are Geographic Information System (GIS) shapefiles of the habitat features.

The "nearshore" is the ribbon of habitat extending from the shallow marine waters of Puget Sound up to the tops of beaches and bluffs. It provides important habitat for young salmon after they have left the freshwater streams where they hatched and reared. Additional information is available on this part of the watershed and how it supports salmon:

• Introduction to the Nearshore
• Nearshore Subwatershed Page
• Central Puget Sound Watershed Page

This information was used to help the Steering Committee of the Green/Duwamish and Central Puget Sound Watershed (WRIA 9) develop and prioritize management actions for the Salmon Habitat Plan. This is one of a series of reports that make up the Strategic Assessment.

This information will also help landowners and local governments better understand the value of the lands under their ownership/jurisdiction.

The preparation of this report was funded with grants from the state Salmon Recovery Funding Board and the King Conservation District.
