The U.S. Fish and Wildlife Service today announced the availability of the draft economic analysis (DEA) for the January 17, 2008, proposed rule to revise critical habitat for the endangered Quino checkerspot butterfly.

Additionally, the Service is reopening the comment period on its proposed rule to revise critical habitat and proposing revisions to proposed critical habitat Unit 2. An advance copy of the DEA, is available online through the Federal Register at Federal Register Public Inspection. However, this copy does not include maps. The official copy, including the maps, will be published in the Federal Register on December 19, 2008.The Service is proposing to revise the boundaries of proposed critical habitat Unit 2 as described in its January 2008 proposed rule. The revision results in the removal of 27 acres of proposed revised critical habitat from two areas along the shoreline of Lake Skinner in Riverside County. Based on new GIS information received, these two areas do not contain the physical and biological features essential to the conservation of Quino checkerspot butterfly because they are primarily wetlands.

Furthermore, based on information received during the initial comment period, additional Department of Defense lands are being considered for exclusion from critical habitat for reasons of national security. Defense lands considered for exclusion include the San Diego Air Force Space Surveillance Station (109 acres) located in proposed critical habitat Unit 8 and Navy-owned La Posta Mountain Warfare Training Facility (1,083 acres) located in proposed critical habitat Unit 9.
The DEA estimates total economic costs associated with the proposed designation of critical habitat to range from $13.1 million to $50.4 million (7 percent discount rate) over the next 23 years, with almost all costs associated with development and Tribal activities. Additionally, with the availability of the DEA, the Service is now considering exclusion of approximately 1,203 acres of Tribal lands of the Cahuilla Band of Indians within proposed Unit 6 and 3,156 acres of Tribal lands of the Campo Band of Kumeyaay Indians within proposed Unit 9 due to high impacts to Tribal economies and Tribal economic vulnerabilities.

Comments and information on the draft economic analysis and on all aspects of the proposed revised critical habitat rule, may be submitted electronically to, or by contacting the Carlsbad Fish and Wildlife Office at 760-431-9440.
