Orcutt's Hazardia [Hazardia orcuttii (Gray) Greene]

Orcutt's Hazardia [Hazardia orcuttii (Gray) Greene]

Listing CNPS List 1B R-E-D Code 3-3-2

State/Federal. Status -- /C2 ASTERACEAE Aug.-Oct.

Global Rank G1G2 State Rank S1.1

Distribution: San Diego County; Baja California, Mexico

Habitat: Open chaparral with Chamise is the habitat for Orcutt's Hazardia at the one known U.S. site (loamy alluvial land of the Huerhuero complex). Diegan Sage Scrub is found on the periphery of this localized population.

Known Sites: A disjunct population of this Baja species is found east of El Camino Real in Encinitas surrounded by a recent housing development.

Thirteen specimens from Baja California are found in the San Diego Natural History Museum's herbarium; south to 31 7' North where collected by Moran (SD 65784) on a mesa 1.5 miles north of Arroyo Salado.

Status: The one known U.S. population is slowly declining; a re-examination in 1989 showed substantial site degradation since viewing the locale three years previously. Inhabitants, especially children, from the newly built residences nearby are now using and expanding footpaths for recreational uses. The potential for accidental fires is substantial. This species is recommended for California Endangered status. Given the degradation at the Encinitas site, it is also recommended that seed by gathered from this population (genetic material may be slightly different in the Baja material given the considerable disjunction) and horticultural material be raised and transplanted into other regionally protected locales. All sites should be protected with adequate buffers.
