Mission Blue Butterfly and San Bruno Elfin Butterfly Monitoring Program, SFPUC Watershed, CA
CLIENT: San Francisco Public Utilities Commission
CRE biologists conduct annual monitoring for the Mission blue butterfly and the San Bruno elfin butterfly on the SFPUC Peninsula watershed. CRE staff conduct egg, larval, and adult surveys throughout the watershed from February to July each year, starting in 2017 to the present. CRE surveys over 150 host plant locations within the San Francisco Peninsula Watershed for the presence of the Mission blue butterfly, and approximately 10 known host plant locations for the San Bruno Elfin. The data from these surveys is used to gain an understanding of the population status of both species and guide management decisions.
