Coastal California gnatcatcher Polioptila californica californica
Goal: Maintain, enhance and restore coastal sage scrub on Conserved Lands in the MSPA that supports or has the potential to support VF species (i.e., cliff spurge, Palmer's goldenbush, San Diego barrel cactus, snake cholla, Blaineville's horned lizard, California gnatcatcher, San Diego black-tailed jackrabbit) and to incidentally benefit a diverse array of other species (e.g., San Diego thornmint, willowy monardella, Hermes copper, Quino checkerspot, coastal cactus wren) so that the vegetation community has high ecological integrity, and these species are resilient to environmental stochasticity, catastrophic disturbances and threats, such as very large wildfires, invasive plants and prolonged drought, and will be likely to persist over the long term (>100 years).

In 2020, implement regional and subregional California gnatcatcher monitoring initiated in 2016 to determine the percent area occupied (PAO) by California gnatcatcher in modeled high and very high suitability habitat on Conserved Lands and military lands in the MSPA as part of a larger monitoring program for southern California. Over the next 15 years, determine trends in California gnatcatcher PAO and in their colonization and extinction rates and be able to detect at least 30% change in PAO. Identify associations between habitat and threat correlates with gnatcatcher PAO and with extinction and colonization rates and develop biologically meaningful thresholds for management and to specify management criteria and recommendations.

When the results of the 2016 California gnatcatcher surveys become available, coordinate with the regional California gnatcatcher survey group made up of wildlife agencies, land managers and scientists, to determine when the next round of regional surveys should be implemented. It is anticipated that the surveys are likely to be held in 2020. Based on the monitoring results and group recommendations, adjust the habitat model and sampling frame as necessary to better predict suitable habitat in the northern extent of the range. |

In 2020, implement California gnatcatcher postfire monitoring conducted in 2015 and 2015 to: determine whether there has been further recovery of California gnatcatchers in areas burned in 2003, 2007 and 2014 (i.e., PAO>10%); evaluate if there is a difference in PAO between areas burned in 2003, 2007 and 2014; investigate the relationship between gnatcatcher PAO and vegetation composition, cover and structure; and evaluate the composition, cover and structure of coastal sage scrub in areas with different fire frequencies and patterns of vegetation recovery based upon time since fire, spatial distribution, previous land use, and environmental conditions. Use the regional gnatcatcher and vegetation monitoring protocols to monitor postfire recovery of gnatcatchers and vegetation at sampling points surveyed in 2016. Analyze gnatcatcher and vegetation data to develop overall and site specific vegetation management recommendations for postfire recovery of coastal sage scrub vegetation to support California gnatcatchers.
