Summary

The objectives of this dataset are to document the geographic distribution of Mohave ground squirrel occurrences, identify important areas for conservation based on available occurrence data, and recommend areas where additional survey effort is needed.

Description

This dataset brings together the data from unpublished field studies and surveys conducted during the 10-year period from 1998-2007, as well as incidental observations. The information presented here includes positive records documenting Mohave ground squirrel occurrence, including data from 102 successful trapping sessions and 96 incidental observations. See the full report at http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=15148.

Supplemental information
The records presented here are from regional field studies, the California Natural Diversity Database (CNDDB), trapping surveys, and incidental observations. A number of regional field studies were conducted during the years 1998-2007, many of them funded by public agencies and private conservation groups. I have reviewed 19 unpublished reports that describe the results of such trapping surveys and have also obtained data from several biologists whose surveys have not been documented in formal reports. The CNDDB contained a total of 293 occurrence records for the Mohave ground squirrel as of August 4, 2007. Twenty-eight new occurrences were submitted during the period from 1998-2007 and there were also 2 new records at previously known locations for the species. I incorporated these 30 records into the data base used in this analysis. The third source of data was trapping surveys carried out at proposed development sites, as required by the California Department of Fish and Game (CDFG). The CDFG requires trapping surveys at proposed development sites according to a prescribed protocol. The CDFG guidelines specify that surveys be conducted on proposed project sites that support desert scrub vegetation and are within or adjacent to the Mohave ground squirrel geographic range. The surveys must be carried out by a qualified biologist operating under authority of a Memorandum of Understanding (MOU) with CDFG. The protocol mandates an initial visual survey of the project site. If no Mohave ground squirrel is detected visually, livetrapping is required for up to 3 sessions of 5 consecutive days each. The trapping sessions must be conducted during the periods March 15-April 30, May 1-31, and June 15-July 15. Trapping grids normally consist of 100 traps arranged in a 4x25 array (linear projects) or in a 10x10 array (other projects). A 4x25 trap array has a length of 840 meters, with the UTM coordinate reported at the center point. In order to obtain the results of protocol trapping surveys for the period 1998-2007, I contacted all biologists who were known to possess an MOU authorizing take of Mohave ground squirrels. The great majority responded by providing their survey data, including dates of trapping sessions, coordinates of grid centers, number of trap-days of sampling effort, and whether or not Mohave ground squirrels were detected. Although I have not obtained data for all protocol trapping efforts, I have collected a total of 943 records that represent 426,615 trap-days of sampling. I estimate that I obtained records for >95% of the total protocol trapping effort for the period 1998-2007. I have classified as incidental observations all reports by biologists who observed or captured Mohave ground squirrels incidental to other field studies. This category includes visual and auditory detections, captures made while trapping for other species, and road mortalities.
