The Center for Biological Diversity submitted a petition to list the Flat‐Tailed Horned Lizard (Phrynosoma mcallii) as endangered throughout their range in California, under the California Endangered Species Act (California Fish and Game Code §§ 2050 et seq., “CESA”).
Flat-tailed horned lizards inhabit the Colorado and Sonoran Deserts in southeastern California, the extreme southwestern portion of Arizona, and into Baja California and Sonora, Mexico. The species is restricted to hot, arid desert habitats typically below 1,000 feet in elevation.
As required by state statue, the California Fish and Game Commission initiated a species review.
The California Department of Fish and Wildlife issued a preliminary evaluation in September of 2014 determining there was sufficient scientific information to indicate that the petitioned action may be warranted. Therefore, the Department recommends the Commission accept the Petition for further consideration under CESA.
The California DFW issued a status review in September 2016. The review has determined that listing the Flat-tailed Horned Lizard as threatened or endangered under CESA is not warranted at this time.
This review is expected to be an agenda topic at the December 7-8, 2016 meeting of the California Fish and Game Commission to be held at:
Hilton Garden Inn San Diego Mission Valley/Stadium
3805 Murphy Canyon Road
San Diego, CA 92123
