Part of the Baskett Slough National Wildlife Refuge, west of Salem. Baskett Butte, the upland portions of the Refuge, has some high-quality prairie and some of the largest populations of the endangered Fender’s blue butterfly (Icaricia icarioides fenderi), the threatened Kincaid’s lupine (Lupinus sulphureus ssp. kincaidii), and the endangered Willamette daisy (Erigeron decumbens var. decumbens).
