摘要

The native prairies of western Oregon and southwestern Washington are among the most endangered ecosystems in the United States. Six native prairie species in the region - one butterfly and five plants - have been added to the Federal List of Endangered and Threatened Wildlife and Plants since 1988. In this recovery plan, we develop recovery strategies and objectives for Fender's blue butterfly (Icaricia icarioides fenderi), Erigeron decumbens var. decumbens (Willamette daisy), Lomatium bradshawii (Bradshaw's lomatium), Lupinus sulphureus ssp. kincaidii (Kincaid's lupine), and Sidalcea nelsoniana (Nelson's checker-mallow). We also provide conservation measures to restore Castilleja levisecta (golden paintbrush) in the Willamette Valley. This plan replaces and supersedes previously approved recovery plans for Lomatium bradshawii and Sidalcea nelsoniana; it augments, but does not replace, the existing recovery plan for Castilleja levisecta. In addition to recovery goals for these six listed species, the plan recommends conservation strategies for one candidate butterfly and six plant species of concern. All of the species addressed in this recovery plan are threatened by the continued degradation, loss and fragmentation of their native prairie ecosystems.
