  • Historic Release of Endangered Light-footed Ridgway's Rails

    Amelia the LFRR by Rinus BaakSeptember 27, 2016

    For the past 6 decades, Light-footed Ridgway's rails (previously called clapper rails) haven't been able to call the southwestern area of San Diego Bay home. Now, thanks to a restoration project completed in 2011, the salt marsh has recovered enough to support the rails again. Six of them were released onto the refuge this week, with five fitted with satellite telemetry so scientists can monitor their movements. Check out our Open Spaces blog for the story, and live video.

    Through a $510,000 grant from the California Coastal Conservancy, neighbors, birdwatchers, and wildlife enthusiasts have a new walking trail to enjoy the beautiful views of the San Diego Bay National Wildlife Refuge. At about 0.4 miles in length and four feet wide, the trail runs parallel with the Bayshore Bikeway from 10th Street to 7th Street in Imperial Beach, California.

    USFWS and San Diego Gas & Electric (SDG&E) are working together to restore 12.44 acres of coastal habitats that were filled in the early 1950s on the San Diego Bay NWR. This project is returning a portion of D Street Fill back to a flourishing salt marsh ecosystem that will benefit endangered and threatened species such as the light-footed Ridgway's rail, California least tern, and also fish populations.
