Current Status
The current overall condition status of the Coastal California Gnatcatcher Species Indicator is Concern based on the two metric condition assessments of Concern. The Percent Area Occupied (PAO) in San Diego County is low (Metric 1) with wildfires reducing PAO relative to unburned areas (Metric 2). There are insufficient data to determine a trend in (PAO) for subregional monitoring of gnatcatchers in San Diego County, whereas post-fire recovery is progressing overall. Additional metrics on habitat quality and management will be added to future reports as more information becomes available.
