Location Details/Description: El Centro Field Office El Centro, CA

The Bureau of Land Management, El Centro Field Office manages approximately 1.4 million acres of public lands spread across two counties: Imperial and San Diego. Approximately 95% of the public lands lie within Imperial County. The area is bordered by the U.S./Mexico International border to the south and the Riverside County line to the north.

Position Overview:

The ACE member will survey and monitor for Flat-tailed Horned Lizards (FTHL) as part of either the demography survey crew or the occupancy survey crew. FTHL have the most limited distribution of any horned lizard species in the USA. There have been multiple attempts to have the species listed at both the State and Federal level which resulted in a multi-agency partnership, development of a Conservation Agreement, and the development and implementation of the FTHL Rangewide Management Strategy (RMS). The RMS provides a framework for the securing and management of sufficient habitat for self-sustaining populations of the FTHL throughout the species range. A central component of the RMS is the designation of five management areas, and the agreement of land management agencies to minimize disturbance within these conservation areas. Three of those management areas are managed by the BLM El Centro Field Office (ECFO). They are the East Mesa Management Area, West Mesa Management Area, and Yuha Management Area.

The ECFO needs demographic surveys completed on 4 plots following the interagency agreed upon survey protocol. 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 RMS whose primary objective is to "maintain self-sustaining populations" of FTHLs.

Additionally, the ECFO needs occupancy surveys completed throughout one of the three Management Areas following the approved occupancy survey protocol. The purpose of conducting occupancy surveys for Flat-tailed Horned Lizards (FTHL) is to detect long-term changes in their spatial distribution. If monitoring is conducted regularly, managers working towards interagency coordination for resource management will know when and where range expansions and contractions occur. If the managers have access to additional information (i.e. environmental conditions) they may be capable of determining the causes of change, thereby making it easier for them to resolve and evaluate any reductions to the range of the FTHL and avoiding any action that may ultimately result in endangering this species further.

Duties will include, but are not limited to:

  • Locate and capture Flat-tailed horned lizards on 4 demographic monitoring plots or on occupancy monitoring plots located throughout a FTHL management area.
  • Collect demographic information such as sex, weight, snout-to-vent length, age, and location.
  • Inject Passive Integrate Transponder (PIT) tags into captured adult lizards for year-to-year tracking and comparison.
  • Humanely collect genetic samples from captured lizards by clipping either the tail or toe and collecting a blood sample.
  • Organize and submit demographic and occupancy survey datasheets, GPS survey data, and GPS survey track logs.
  • May be required to operate a motor vehicle.

This individual placement is meant to facilitate professional development and promotes exposure to land management agencies and networking with professionals. This could include gaining experience in different conservation fields and resource areas, assisting with additional biological projects, and shadowing different work groups within the ECFO.
