Raster data files for Prioritizing conserved areas threatened by wildfire for monitoring and management. Raster data files for Prioritizing conserved areas threatened by wildfire for monitoring and management.
The data set consists of 12 input data rasters that cover San Diego County, California. These input rasters represent criteria used in a Pareto ranking algorithm in the manuscript. These include three rasters related to fire threats, three rasters related to habitat fragmentation threats, four rasters related to species biodiversity, and two rasters related to genetic biodiversity.

Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015) Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015)
This habitat model was developed to delineate a sampling frame for regional monitoring of coastal California gnatcatchers (Polioptila californica californica) to determine: 1) percent area occupied (PAO) in high and very high suitability habitat across conserved lands and participating military lands in the U.S. range in southern California; 2) changes in PAO over time; and 3) extinction...
Least Bell's Vireo Habitat Suitability Model for California (2019) Least Bell's Vireo Habitat Suitability Model for California (2019)
This habitat model was developed to identify suitable habitat for the federally-endangered least Bell's vireo (Vireo bellii pusillus) across its current and historic range in California. The vireo disappeared from most of its range by the 1980s, remaining only in small populations in southern California. Habitat protection and management since the mid-1980s has led to an increase in...

Genetic and environmental factors associated with survival of a rare songbird in a fragmented urban landscape Genetic and environmental factors associated with survival of a rare songbird in a fragmented urban landscape
The coastal Cactus Wren (Campylorhynchus brunneicapillus) persists in small and fragmented populations throughout southern California that are subject to genetic drift and inbreeding. We combined individual banding and resighting data and genotyped individuals at 22 microsatellite loci to assess whether heterozygosity was associated with survival across three regional Cactus Wren...

Science support for recovery of Southwestern Willow Flycatcher (Empidonax traillii extimus) on conserved lands in San Diego County Science support for recovery of Southwestern Willow Flycatcher (Empidonax traillii extimus) on conserved lands in San Diego County
This document was developed based on the results of scientific research to support management and recovery of the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus) and its habitat in San Diego County, California. A migratory species restricted to riparian habitat for breeding, the flycatcher is present in southern California from May to August. The flycatcher has...

Quantification of threats to bats at localized spatial scales for conservation and management Quantification of threats to bats at localized spatial scales for conservation and management
In a rapidly changing world, where species conservation needs vary by local habitat, concentrated conservation efforts at small spatial scales can be critical. Bats provide an array of value to the ecosystems they inhabit; many bat species are also of conservation concern. San Diego County, California, contains 22 of the 41 bat species that occur in the United States, 16 of which are on

2023-2024 Coastal sage scrub and chaparral community monitoring for western San Diego County 2023-2024 Coastal sage scrub and chaparral community monitoring for western San Diego County
Western San Diego County is dominated by shrublands supporting biologically diverse native plant and animal communities. Widespread urbanization has led to regional habitat loss and fragmentation, and many species in these shrubland communities are rare, threatened, or endangered. Large-scale, multiple-species conservation planning has resulted in a regional preserve system that focuses...

Occupancy dynamics of the California Gnatcatcher in southern California Occupancy dynamics of the California Gnatcatcher in southern California
Executive Summary The Coastal California Gnatcatcher (Polioptila californica californica: “gnatcatcher”) is a resident species restricted to coastal sage scrub habitat in southern California. Listed as federally threatened, the gnatcatcher is subject to multiple threats, including habitat loss, fragmentation, and degradation, particularly in association with the increasing frequency of...

Rangewide occupancy of a flagship species, the Coastal California Gnatcatcher (Polioptila californica californica) in southern California: Habitat associations and recovery from wildfire Rangewide occupancy of a flagship species, the Coastal California Gnatcatcher (Polioptila californica californica) in southern California: Habitat associations and recovery from wildfire
The Coastal California Gnatcatcher (Polioptila californica californica), a federally threatened species, is a flagship species for regional conservation planning in southern California (USA). An inhabitant of coastal sage scrub vegetation, the gnatcatcher has declined in response to habitat loss and fragmentation, exacerbated by catastrophic wildfires. We documented the status of...
