The distribution and status of four plant and nine animal species being considered by the US Fish and Wildlife Service (FWS) for protection under the Endangered Species Act and one animal species recently listed in the Act as endangered was determined for the Naval Petroleum Reserves in California (NPR-1 and 2). Hoover's woolly-star (Eriastrum hooveri), a Category 2 plant species, was located at 28 sites on NPR-1. The California jewelflower (Caulanthus californicus), Kern mallow (Eremalche kernensis), and San Joaquin woolly-threads (Lembertia congdonii) were not observed. Of these, the Kern mallow is most likely to occur based on habitat utilization and autecology. No evidence was gathered that suggests the Buena Vista Lake shrew (Sorex ornatus relictus) was present on either of the Reserves. Nelson's antelope ground squirrel (Ammospermophilus nelsoni) and the short-nosed kangaroo rat (Dipodomys nitratoides brevinasus) are both Category 2 mammals that were relatively abundant on NPR-1 and 2. The San Joaquin pocket mouse (Perognathus inornatus) was also captured on NPR-1 and 2, but was less numerous. The Tipton kangaroo rat (Dipodomys nitratoides nitratoides), a recently listed endangered species, was found in Section 23S of NPR-1 and Section 18H of NPR-2. No evidence was found that Morrison's blister beetle (Lytta morrisoni), Moestan blister beetle (Lytta moesta), Hopping's blister beetle (Lytta hoppingi), and the Molestan blister beetle (Lytta molesta) exist on either of the Reserves. Similarly, a survey conducted for the striped-skinned snail (Helminthoglypta callistoderma) found no evidence that the snail exists on either of the Reserves. No additional surveys for candidate species that were undetected are needed unless new evidence is collected that suggests the species are or may be present. 17 figs., 7 tabs.
