Biological survey of Naval Petroleum Reserve No. 2 (Buena Vista), Kern County, California
A field survey of Naval Petroleum Reserve No. 2, Kern County, California, was conducted to determine the distribution and relative abundance of endangered species and other wildlife. Of the 343 San Joaquin kit fox dens found in 40 sections, 33 were observed by surveyors in transit and 310 were found along transects. Of the latter, 264 were typical subterranean dens and 46 were atypical dens in man-made structures. Estimated density of dens was 28.8 +- 4.4 per square mile; relative density was 9.2/1000 acres. The number of typical dens observed per section was inversely correlated with the number of petroleum wells per section (intensity of development). Atypical dens were usually found to be in pipes or pipe culverts and were positively correlated with density of wells. Relative densities of black-tailed jackrabbits (41.9/1000 acres) and desert cottontails (17.1/1000 acres), preferred prey for foxes, were high compared with densities reported on other public lands. Most (81%) of the 19 blunt-nosed leopard lizards were observed in six adjacent sections located in the gentle foothills near Buena Vista Lake playa. Most (86%) of the 275 giant kangaroo rat burrow systems were observed in ten sections containing flat, relatively undeveloped terrain in and around upper Buena Vista Valley. San Joaquin antelope ground squirrels were the second most commonly observed diurnal vertebrate: 761 observations in 45 sections. A total of 6740 observations of 61 species of wildlife were made.
