BLM-CA Awards GeomorphIS Flat-tailed Horned Lizard Demographic Survey Task Order
The Bureau of Land Management (BLM) California State Office has contracted with the GeomorphIS-San Diego Natural History Museum (SDNHM) team to conduct flat-tailed horned lizard (Phrynosoma mcalli; FTHL) demographic surveys within the BLM El Centro Field Office area, in Imperial County, California, during the 2020 season. The areas to be surveyed include the East Mesa Management Area, West Mesa Management Area, and Yuha Management Area. The purpose of FTHL demographic surveys is to gather information on population dynamics that can be used to characterize local populations through time. These surveys can aid in the detection of year to year trends in abundance, recruitment, and survivorship. The data gathered in demographic surveys supports the
management strategies outlined by the Rangewide Management Strategy (RMS). Plots will be surveyed following the standard protocol and FTHLs captured will be PIT tagged or toe-clipped, marked, measured, and data sheets filled out.
