Data presented are results of surveys in 2021 for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. Surveys were conducted at 378 plots. Plots were surveyed twice in 2021 and the number, age (adult or juvenile), banding status (color banded or not), and breeding status (paired, unpaired, or unknown) of all wrens recorded. Habitat covariate data were collected including amount of dead and stressed cactus in the plot, percent cover of bare ground, and the dominant and percent cover of invasive species.

Data presented are results of surveys in 2021 for Southwestern Willow Flycatcher (Empidonax traillii extimus) in San Diego County, California. Surveys were conducted at the 2016-19 nest monitoring locations (Cleveland National Forest, Rey River Ranch, and Vista Irrigation District) and at Lake Henshaw along the Upper San Luis Rey River. Surveys were conducted along multiple sections of the river where permission to access properties could be obtained. Locations were surveyed using a standardized protocol three to four times between 15 May and 31 July. The number, age (adult or juvenile), sex, banding status (color banded or not, and if so, color combination), and breeding status (paired, undetermined, or transient)...

To understand the genetic structure of six rare plant species (Acanthomintha ilicifolia, Baccharis vanessae, Chloropyron maritimum ssp. maritimus, Deinandra conjugens, Dicranostegia orcuttiana, Monardella viminea), we obtained samples from known occurrences in San Diego County, prepared and sequenced ddRAD genomic libraries, and developed and analyzed a panel of genetic markers to assess population diversity and divergence. We provide this SNP genotype dataset in Structure format, produced in Stacks v2.0b8, for future monitoring efforts and population genetic analysis. These data support the following publication: Milano, E.R., and Vandergast, A.G., 2018, Population genomic surveys for six rare plant species in...

We surveyed for Least Bell’s Vireos (Vireo bellii pusillus; vireo) and Southwestern Willow Flycatchers (Empidonax traillii extimus; flycatcher) along the San Luis Rey River, between College Boulevard in Oceanside and Interstate 15 in Fallbrook, California (middle San Luis Rey River), in 2021. Surveys were conducted from April 13 to July 14 (vireo) and from May 18 to July 13 (flycatcher). We found 180 vireo territories, at least 125 of which were occupied by pairs. The vireo population size decreased by 6 percent from 2020 to 2021. One resident flycatcher, of undetermined breeding status, was observed in the survey area in 2021. He was detected from May 20 to June 4, 2021, and no evidence of pairing or nesting was...

Data presented are results of surveys for California Gnatcatchers and vegetation sampling conducted in 2015 and 2016 to address two inter-related questions: (1) How have gnatcatchers and their habitat recovered in areas burned by wildfires in 2003, 2007, and 2014?, and (2) What is the current regional occupancy of gnatcatchers throughout their southern California range? Data for the post-fire study were collected in 2015 and 2016, while the regional occupancy survey was conducted in 2016. In 2015, Gnatcatcher occupancy as a function of fire history was derived from 324 points in the following fire categories: 2003-2006 (106 points), 2007-2010 (111 points), and 2011-2014 (107 points). In 2016, points representing...

Data presented are results of surveys (2015) and monitoring (2015 and 2016) for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. Surveys were conducted at 35 plots. Plots were surveyed twice in 2015 and the number, age (adult or juvenile), banding status (color banded or not), breeding status (paired, unpaired, or unknown), and nesting status (active nest detected or not) of all wrens recorded. Habitat covariate data were collected including amount of dead and stressed cactus in the plot, percent cover of bare ground, and the dominant and percent cover of invasive species. During weekly monitoring visits, nests were located and checked to determine the number of eggs laid, the...

Drainage areas (or watersheds) were calculated for each stream segment in the National Hydrography Dataset High Resolution Plus Beta (NHD HR Plus Beta) using non-end junction points and the provided hydrologically enforced Digital Elevation Model (DEM). The DEM was used to create a flow direction raster. The pour points used were determined from junction points at each stream intersection excluding stream ends (i.e. channel heads are not included). Watershed calculations were automated using the ArcGIS "watershed" tool and then edited manually for accuracy. In western San Diego County (non-desert) there were 39,980 drainage areas calculated. The percent impervious in each watershed was calculated using the National...

Data presented are results of surveys and monitoring for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. These data were collected to assess Cactus Wren population status to determine the relationships between specific elements of habitat quality and Cactus Wren presence. Surveys were conducted periodically at 507 plots throughout San Diego County. Birds that had been banded in prior years with unique color combinations were identified to individual on subsequent visits to provide data on survival and movement between years. These data support the following publication: Lynn, S., and Kus, B.E., 2023, Distribution and demography of coastal Cactus Wrens (Campylorhynchus brunneicapillus)...

The goal of this project was to primarily assess east-west connectivity across Route 67 and secondarily, north-south connectivity across Scripps Poway Parkway and Poway Road, two highly trafficked roads to the west of Route 67. We collected deer scat piles from both sides of these crossings in spring between March and June of 2015, and again in fall throughout October 2015. Collected pellets were extracted and amplified using protocols and loci developed by Bohonak and Mitelberg (2014). DNA fingerprinting results were used to investigate mule deer movement in the region directly by identifying individuals which had been captured multiple times throughout the study period. We also assessed movement indirectly through...
