Impact of Space Shuttle Support Facilities Construction on Special Interest Plant Species (Vandenberg AFB, Calif).

摘要

This report summarizes the results and conclusions of studies conducted to evaluate the impact of ground support facility construction for the Space Shuttle program at Vandenberg AFB, California on listed and proposed threatened or endangered plant species in order to comply with the Endangered Species Act of 1973. Vegetation surveys were made in proposed construction site areas. The listing used to determine threatened and endangered plant taxa were those plant species proposed as endangered or threatened in the 1975 Federal Register (40FR27824-27890) and those listed as endangered for rulemaking by the US Fish and Wildlife Service in the June 16, 1976 Federal Register (41FR24524-24572). The surveys also included other special interest taxa designated by the California Native Plant Society as being rare, endangered, or vascular plants of limited distribution in California. Three threatened species (Castilleja mollis, Monardella crispa, and Scrophularia atrata) and two endangered species (Cirsium rhothophilum and Erigeron foliosus var blochmanae) were found in a number of the construction site areas. It was determined that construction activities would not jeopardize the continued existence of any of these species. Mitigative measures were recommended to minimize adverse plant habitat modification or removal of any of these plants. (Author)
