ETWP; Endangered Status for Erigeron decumbens var. decumbens (Willamette Daisy) and Fender's Blue Butterfly (Icaricia icarioides fenderi) and Threatened Status for Lupinus sulphureus ssp. kincaidii (Kincaid's Lupine)

The U.S. Fish and Wildlife Service (``Service'' or ``we'') determines endangered status pursuant to the Endangered Species Act (Act) of 1973, as amended, for a plant and a butterfly, Erigeron decumbens var. decumbens (Willamette daisy) and Fender's blue butterfly (Icaricia icarioides fenderi), and determines threatened status for a plant, Lupinus sulphureus ssp. kincaidii (Kincaid's lupine). These species are restricted primarily to native prairie in the Willamette Valley of Oregon and are known currently from a few small remnants of a formerly widespread distribution. In addition to its Oregon occurrences, L. sulphureus ssp. kincaidii is known also from two small sites in southern Washington. Commercial and/or residential development, agriculture, silvicultural practices, road improvement, over-collection, herbicide use, and naturally occurring demographic and random environmental events threaten these three taxa. This final rule invokes the Federal protection and recovery provisions of the Act, as applicable for these plant and butterfly species.
