Distribution and Status of Sclerocactus polyancistrus on the Naval Weapons Center-A Survey

摘要

Sclerocactus polyancistrus, a highly vulnerable plant with a history of having been extensively collected, is listed in recent publications as a threatened species. Military reservations and other areas that restrict public access may represent a final refuge for the plant. This report presents the results of a survey performed to determine the status of Sclerocactus polyancistrus on the Naval Weapons Center, China Lake, Calif. In addition to enabling the Navy to comply with Section 7 of the Endangered Species Act of 1973, which requires federal agencies to protect threatened or endangered species as determined by the Secretary of the Interior, the survey provides a convenient reference source for the Navy in support of current and future environmental studies and land management programs.
