Monitoring of species found within the MSCP is a key method to measuring the success of the reserve system. The Coastal Cactus Wren is one of the focal species identified as part of the MSCP Biological Monitoring Plan. The species is also currently on the State of California Birds of Species Concern list. The primary threat to the cactus wren is habitat loss and concurrent fragmentation, which occurs as habitat is developed or fire destroys cactus. The coastal cactus wren historically occurred in cactus patches along the several lagoons and coastal canyons in San Diego and southern Orange County (Rea and Weaver 1990), though recent surveys reveal that most of these populations have been destroyed by urbanization (Rea and Weaver 1990, USFWS 1994). The remaining coastal cactus wren populations in San Diego County are predominantly in the inland portion of the county (Rea and Weaver 1990). This datalayer presents the positive observations of USFWS Cactus Wren occupancy surveys conducted in San Diego County in 2011 and was compiled as part of the Southern California Data Integration Project. Extensive cactus mapping was conducted in San Diego County prior to the survey effort. Cactus wren monitoring was done within an occupancy framework to determine the percentage of plots occupied by cactus wrens, estimated from plot surveys. Surveys were conducted from April 26-June 7, 2011 between sunrise and sunset. Each plot was visited up to 3 times during the survey season. Environmental measurements (air temperature, average wind speed) were recorded during a 1-minute period upon arriving at a sample point using a pocket weather station. Surveys were not conducted if average wind speeds exceeded 20 kilometers per hour, precipitation exceeded a drizzle, or ambient temperatures were less than 4.5C (40F) or over 30C (85F). Surveyors used tape playback of cactus wren song to elicit response of cactus wrens on the plot to aid detectability. Following Mitrovich and Hamilton (2007), the tape was played for three 40 second intervals with one minute of silence in between. The surveyor listened and watched for cactus wrens as the tape was played and for one minute after each tape playback. Presence or absence of cactus wrens on the plot was recorded on a datasheet, as well as the number of juveniles, adults, or birds in which the life stage could not be determined. Additional information about the survey or bird was noted in the Comments field, such as whether a nest was observed. Habitat data were collected for each plot as well but are not presented here.

The purpose of this dataset is to assess Cactus Wren populations and their associated habitats on MSCP lands. Initial surveys were conducted in 2009 (ds702) and again in 2011 in attempt to build a unified and cohesive data set. Questions to be answered include: What are the relationships between cactus patch size, the quantity/quality/variety of associated vegetation, and the numbers of breeding pairs within a patch? How many patches of cactus have no wrens? What are the site and landscape characteristics of these patches as compared to patches that contain wrens? Is dispersal occurring between the current populations? Will populations be viable in the long-term? How vulnerable are individual subpopulations or is the population as a whole to fire?

This map is based on occurrence data. Data used for this project was limited to 2011. All field surveys required surveyors to GPS their survey points. Utilizing this data, the initial survey point (ISP) was then corrected in ArcGIS (unless ISP was used) to indicate where surveys occurred during the 2011 field season. N/A The initial shapefile of survey points was created by Tyler Grant as the initial survey point for CACW surveys. Initial point placement was performed in office. In-situ surveys by CACW surveyors corrected a portion of these survey points to adjust for visual obstructions such as topographical features and vegetation. 20090901 CACW observations from the 2011 surveys were queried from an Access database and imported into ArcMap 10.0 20090901 This dataset was converted from UTM Zone 11N NAD83 to California Teale Albers NAD83 by the California Department of Fish and Game (DFG).
