This annual herb is listed as endangered. It occurs largely on lands managed by the U.S. Bureau of Land Management, where it is threatened by off-highway vehicle recreation and the resultant accelerated erosion in its habitat. Its habitat consists of mostly alluvial terraces in areas of serpentine rock. This rock type is rather toxic to most plants because it provides an unusual balance of plant nutrients. Serpentine areas generally have sparse vegetation.
Serpentine dust is toxic to people because it contains asbestos.
The objective of this plan is to conserve the plant so that protection by the Act is no longer necessary. The plan also seeks to protect populations of the plant on private lands, protect populations from activities other than off-highway vehicular recreation, and to develop a public awareness program. Public Comments Solicited The Service solicits written comments on this draft recovery plan. All comments received by the date specified above will be considered prior to final approval of this plan.
