The Hidden Lake bluecurls plant is known to occur only at Hidden Lake in Mount San Jacinto State Park, in Riverside County, Calif.

The U.S. Fish and Wildlife Service published a final rule on September 25, 2007, determining that designating critical habitat for the federally threatened Hidden Lake bluecurls plant is not prudent. 

This final rule was prepared in accordance with a 2005 settlement agreement stemming from a lawsuit filed against the Service by the Center for Biological Diversity and the California Native Plant Society. The lawsuit challenged the Service?s initial 1998 not prudent finding.

Pursuant to the settlement agreement, the Service agreed to withdraw its previous not prudent determination to re-evaluate the possible benefits and drawbacks associated with designating critical habitat for Hidden Lake bluecurls.

On September 26, 2006, the Service published a proposed not prudent finding regarding critical habitat for the Hidden Lake bluecurls. After analyzing information and comments received, the Service determined that the designation of critical habitat may increase the degree of threat to the species and undermine the conservation actions undertaken by the California Department of Parks and Recreation (CDPR) to conserve the plant.

Hidden Lake bluecurls is a member of the mint family and is known to only occur at Hidden Lake in Mount San Jacinto State Park in Riverside County, California.

The plant was listed under the Endangered Species Act based on threats from trampling by people and horses, and low numbers of individual plants. The CDPR has taken steps to reduce threats from trampling by installing an additional barrier to exclude equestrian use, removing plant locational information from trails and brochures, and designating the area where the plant occurs as a Natural Preserve.
