Restoring Habitat for the Coastal Cactus Wren
The coastal Cactus Wren is a California State Species of Special Concern due to habitat loss. Two restoration projects were conducted at the UCI Ecological Preserve in collaboration with the Natural Communities Coalition to support Wren populations at the Preserve and in surrounding natural areas. One project focused on facilitating dispersal among isolated populations by restoring habitat between them. Cactus Wrens utilize larger clumps and taller cactus interspersed throughout coastal sage scrub plant communities. Restoration in this project entailed transplanting cactus pads and whole cactus plants salvaged from areas undergoing development into existing scrub habitat. The other restoration project focused on both planting cactus and on restoring areas dominated by non-native weeds with a diverse plant assemblage from the coastal sage scrub community. This enhances both nesting and foraging habitat for the wrens. Efforts continue to maintain the quality of this habitat and to monitor the population status of the coastal Cactus Wren on the UCI Ecological Preserve.
