- Mount Saint Helens Wildlife Area (wdfw.wa.gov)
The Mount St. Helens Wildlife Area is comprised of units that span Skamania, Clark, Cowlitz, and Wahkiakum counties, and totals approximately 10,500 acres of land. Habitat include tidal mudflats, wetlands, riparian, old-growth forest,forested floodplains, early seral mixed forest, ancient lava flows and volcanic deposits, and open grasslands. The units receive the most attention from a wildlife management perspective and provide some of the most critical winter range habitat for a portion of the Mount St. Helens Elk Herd. Many of the units support salmonid rearing and spawning habitat for threatened or endangered fish species.
