Summary
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 following 3 years of drought and determine the relationships between specific elements of habitat quality, food availability, and Cactus Wren productivity and survival. Surveys were conducted periodically at 35 plots that were last surveyed in 2012. A subset of Cactus Wren territories were monitored in the Otay and Sweetwater/San Diego genetic clusters to ascertain Cactus Wren breeding productivity, survival, and associated vegetation composition and structure. Nesting data were compiled to present seasonal productivity for each [...]
Summary
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 following 3 years of drought and determine the relationships between specific elements of habitat quality, food availability, and Cactus Wren productivity and survival. Surveys were conducted periodically at 35 plots that were last surveyed in 2012. A subset of Cactus Wren territories were monitored in the Otay and Sweetwater/San Diego genetic clusters to ascertain Cactus Wren breeding productivity, survival, and associated vegetation composition and structure. Nesting data were compiled to present seasonal productivity for each Cactus Wren pair. All nestlings and adults (when possible) were color banded with unique color combinations to identify individuals on subsequent visits to provide data on survival within and between years. Habitat data were collected at survey plots during the first year of the survey and at monitoring sites during all years.

The authors of these data require that data users contact them regarding intended use and to assist with understanding limitations and interpretation. These data are preliminary or provisional and are subject to revision. They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data.
Purpose
The two goals for collecting these data were to assess Cactus Wren population status following the 2014 drought and to monitor execution of San Diego Association of Governments (SANDAG) Implementation Plan’s highest priority management actions including determining the relationships between specific elements of habitat quality, food availability, and Cactus Wren breeding productivity and survival, and using this to refine management actions to increase population abundance and resilience.
