Cactus Wren Monitoring in southern San Diego County

This is a planned 5-year study with two main goals: 1) Assess the population status of the coastal cactus wren following the 2014 drought and 2) monitor the implementation of the MSP 2015 Habitat Conservation and management Plan's highest priority management actions. In the first year, the population status of cactus wren in MUs 3 and 4 was assessed to determine the relationship between habitat quality, food availability, and cactus wren productivity and survival. In 2017, the focus is on monitoring cactus wren reproduction and survival and conducting vegetation sampling. Specific management recommendations will be developed to respond to short-term emergency needs and to enhance habitat for long-term cactus wren persistence. Continued monitoring will be done annually.
