Coastal Cactus Wren Conservation Network

in progress

Project description

The Coastal Cactus Wren Conservation Network is an ad hoc group of more than 100 individuals representing research institutions, land management agencies, local government, non-profit conservation organizations and wildlife agencies. Members work together to exchange research and management information to develop best practices, policies, and programs that promote conservation and recovery of this bird throughout its range (Ventura, Los Angeles, San Bernardino, Orange, Riverside, and San Diego counties). This information will inform publication of a regional conservation strategy for the coastal cactus wren. Cactus wrens (Campylorhynchus brunneicapillus) are distributed across the arid regions of the southwestern United States and northern and central Mexico (Hamilton et al. 2011). While the desert populations are fairly abundant, populations of coastal cactus wrens have declined dramatically over the past 30 years, with extirpation and genetic isolation affecting many locations as a result of habitat loss, habitat fragmentation, edge effects of development, and catastrophic fires (Solek and Szijj 2004). The coastal population is unique in that it occurs exclusively within the coastal sage scrub plant community, ranging from Ventura County south into San Diego County, U.S.A. and northwestern Baja California, Mexico. The firestorms of 2007 impacted several strongholds for the coastal cactus wren in Orange and San Diego counties. The significant loss of habitat and birds was the impetus for formation of the Coastal Cactus Wren Network.
