For years, the federally endangered San Mateo thornmint was known from only one location at Edgewood Natural Preserve in Redwood City. In the last two seasons, Creekside Science has seeded three new locations within the Preserve, bringing the total number of San Mateo thornmint to 7,549 in May 2017, its highest since we began monitoring in 2007. This January, we seeded a new location at nearby Pulgas Ridge, thanks to funding and support from San Francisco Water, Power and Sewer. We hope to be instrumental in creating the five self-sustaining populations required by the U.S. Fish and Wildlife Service’s Recovery Plan to downlist this taxon. Other partners include Friends of Edgewood, Yerba Bioadvocacy, San Mateo County Parks, California Native Plant Society, U.C. Berkeley Botanical Garden, San Mateo County Parks Foundation, Mellam Family Foundation, California Department of Fish and Wildlife, and U.S. Fish and Wildlife Service.

The federally threatened Bay checkerspot butterfly was extirpated from San Bruno BCB_Larva_lanceolata_munch_SBM 3-1-2017 4-51-20 PM (1)Mountain in the mid 1980s.  On March 2 and 3 2017, Creekside Science biologists collected 3630 caterpillars from Coyote Ridge in San Jose and released them on the main ridge of San Bruno Mountain.  The larvae immediately started munching English plantain, a  non-native used by other closely related checkerspot populations.  The cool coastal environment, robust perennial hostplant, and extensive habitat are encouraging aspects of this project.  This project may show that we can reintroduce extirpated species without the technical challenges and expense of restoring all historical conditions.

Find the very hungry caterpillar!

Many thanks to the Disney Butterfly Conservation Initiative, US Fish and Wildlife Service, San Mateo County Parks and Recreation, and SF Bay Wildlife Society for financial and professional support.

Creekside Science Quino checkerspot work

Creekside Science is working in collaboration with numerous agencies and institutions, including the US Fish and Wildlife Service (USFWS), San Diego National Wildlife Refuge, San Diego Zoo, San Diego State University and Earth Discovery Institute, on reversing the decline of the critically endangered Quino checkerspot butterfly (Euphydryas editha quino) in San Diego County.  Dr. Weiss has gone down to San Diego County a few times for field work, and he will be going again soon when the Quino checkerspot butterflies start flying.
