## Abstract

The Fish and Wildlife Service (Service) determines endangered status for Pseudobahia bahiifolia (Hartweg's golden sunburst) and threatened status for Pseudobahia peirsonii (San Joaquin adobe sunburst) pursuant to the Endangered Species Act of 1973, as amended (Act). The two plants occur primarily in nonnative grasslands in the eastern and southeastern portions of the San Joaquin Valley, but also at a few sites at the ecotone between grasslands dominated by nonnative species and blue oak woodland communities. Both plants are threatened primarily by conversion of habitat to residential development. To a lesser extent, the species are variously threatened by agriculture (ag- land development), competition from nonnative plants, incompatible grazing practices, transmission line maintenance, recreational activities, mining, road construction and maintenance, a flood control project, and other human impacts. Potential threats include herbicide application to control herbaceous and weedy taxa. This rule implements the Federal protection and recovery provisions afforded by the Act for these species.
