Mud Slough Wetland, located west of Salem, is one of the most diverse, productive wetlands in western Oregon. The site features a range of diverse shallow water habitats and vegetation, from small native sedges to taller cattails and rushes, as well as a single deeper pond. Willow patches and restored native wetland prairie are also present. The lack of invasive plant and animal species can be attributed to the site preparation done prior to restoration and the continued vigilance of the landowner.
Virginia Rail, Sora, and American Bittern, use this wetland as a place to breed. During spring and fall, hundreds of shorebirds can be found foraging. During fall and winter, several thousand waterfowl and shorebirds (mainly Dunlin) can be seen. Birds otherwise rare in western Oregon, including Black-necked Stilt, Wilson's Phalarope, and the Yellow-headed Blackbird, are known to breed here.
