Saturday November 17, 2012, 9:00am-1:00pm: Cactus Monitoring on the San Diego National Wildlife Refuge
Join refuge staff to make important observations about Coastal cactus wrens. Cactus wrens are fairly common in the desert, however, in coastal Southern California they are declining because they rely on a rare habitat type—cactus scrub especially prickly pear and cholla—for nesting, foraging, and protection. Unlike most other birds, cactus wrens use nests year round for roosting (sleeping); they build a covered, football-shaped nest with grasses and other vegetation. The small populations of coastal cactus wren in Southern California are becoming more and more isolated from each other because of habitat loss and fragmentation due to urbanization and wildfire. Active restoration is underway on the San Diego National Wildlife Refuge to accelerate habitat recovery for the coastal cactus wren.
Guided by refuge biologist, John Martin, volunteers will visit the restoration sites to observe and record the condition of the cactus, the wrens, and any invasive plants or animals. Wear long pants, a hat, and sturdy shoes. Bring sunscreen or rain protection, as the weather indicates. Bring water and a water bottle if you have one. Tools, equipment, water and snacks will be provided. We are happy to sign for community service or extra credit hours. To RSVP, and for directions or more information, contact Cathy Chadwick, info@earthdiscovery.org or 619-447-4715.
