NISQUALLY NATIONAL WILDLIFE REFUGE - Washington, USA
Nisqually National Wildlife refuge located just off Interstate 5 in Washington States Southern Puget Sound is home to a large number of both resident and migratory birds as well as several species of Pacific Salmon.
Permapost K-520 (Copper Naphthenate) pressure treated wood was a natural choice for this project because of its ability to blend in with the environment and its long-standing performance record in similar applications. The refuge is visited by over 100,000 people each year.
