The California Department of Fish and Wildlife (CDFW) is seeking information relevant to a proposal to list the flat-tailed horned lizard as an endangered species.
The flat-tailed horned lizard (Phrynosoma mcallii) inhabits desert habitats in southeastern California, the extreme southwestern portion of Arizona and the adjacent portions of northeastern Baja California Norte and northwestern Sonora, Mexico. This species has the smallest range of any horned lizard in the United States. Approximately one-quarter of the flat-tailed horned lizard’s range is in California, where it is confined to lower elevations throughout much of the Salton Trough, sections of eastern San Diego County, central Riverside County and western and south-central Imperial County.
In June 2014, the Center for Biological Diversity (CBD) submitted a petition to the California Fish and Game Commission (Commission) to formally list the flat-tailed horned lizard as endangered under the California Endangered Species Act. The listing petition described a variety of threats to the survival of flat-tailed horned lizards in California. These include direct and indirect impacts associated with agricultural, urban and renewable energy development, on- and off-road vehicles, habitat fragmentation, barriers to movement, military training and border activities, nonnative plants and climate change. CDFW recommended and the Commission voted to advance the species to candidacy on February 12, 2015. The Commission published findings of this decision on February 24, 2015, triggering a 12-month period during which CDFW will conduct a status review to inform the Commission’s decision on whether to list the species.
As part of the status review process, CDFW is soliciting information from the public regarding the species’ ecology, genetics, life history, distribution, abundance, habitat, the degree and immediacy of threats to reproduction or survival, adequacy of existing management and recommendations for management of the species. Comments, data and other information can be submitted in writing to:

Comments may also be submitted by email to firstname.lastname@example.org. If submitting comments by email, please include “flat-tailed horned lizard” in the subject heading.
All comments received by September 14, 2015 will be evaluated prior to submission of the CDFW report to the Commission. Receipt of the report will be placed on the agenda for the next available meeting of the Commission after delivery and the report will be made available to the public at that time. Following the receipt of the CDFW report, the Commission will allow a 30-day public comment period prior to taking any action on CDFW’s recommendation.
CBD’s listing petition and CDFW’s petition evaluation for the flat-tailed horned lizard are available at fgc.ca.gov/regulations/2014/index.aspx#fthl.
