About the Symposium

The San Francisco Bay Area Chapter of the Wildlife Society, in collaboration with the Alameda County Resource Conservation District, is excited to present a symposium on the ecology, management and regulation of three at-risk grassland-associated butterfly species: the Callippe silverspot (Speyeria callippe callippe, federally endangered), Bay checkerspot (Euphydryas editha bayensis, federally threatened) and monarch (Danaus plexippus, federal candidate species).

The two-day workshop will consist of one day of presentations with butterfly experts, land managers and regulators, plus a half-day field trip. The lecture portion will occur at virtually on April 22. The optional field trip will take place at the 3 Calhoun Sisters' Ranch, off of Mines Rd. in Livermore on April 23. The Calhoun Sisters are part of a local ranching family that has been farming and ranching in eastern Alameda County for over 100 years. Their property hosts a diversity of sensitive native wildlife species and habitats, including that which supports monarch butterflies and other pollinators, as well as the host plant of Callippe silverspot. The Calhoun Sisters emanate an environmental ethic of regenerative agriculture and are wonderful teachers through their own learned experience of natural resource stewardship on their land. At the field site we will visit host plants for the Callippe silverspot and monarch butterfly. There are two options for the field trip - Saturday morning or Saturday  afternoon.
