Program Description

If you want to see certain unusual cacti and succulents in the wild, you must travel to the specific small islands where they grow. This is especially true in Baja California, where plants have evolved rapidly in response to their island habitats. This talk provides a tour of two ecosystems, with detailed pictures and information on all the endemic cacti and succulents on three islands. Two are in the Pacific Ocean, off the west coast of Baja: Isla Cedros, and Isla Magdalena. There is also an introduction to the wild west side of Isla Angel de la Guarda in the Gulf of California.

Peter started studying cacti in habitat more than 30 years ago and at age 58 earned a Ph.D. from Arizona State in cactus evolution and biogeography, focused on the Mammillaria and Cochemiea of Baja California. He is one of the authors of The Field Guide to Cacti and Succulents of Arizona, published by the Tucson Cactus and Succulent Society. He is currently a postdoctoral research fellow at The Desert Lab at The University of Arizona, conducting the sixth installment since 1964 of the long-term saguaro survey on Tumamoc Hill in Tucson. He is the managing editor for CSSA publications, and edits both the Cactus and Succulent Journal and the annual peer-reviewed yearbook, Haseltonia.

Show & tell table: bring Ferocactus, Agave, or whatever is in flower or looking nice.

Featured grower: Annie Wolf - Desert Wonders Plants

Snack table:, There will be a shared spread, but we suggest bringing something every couple of months if you partake regularly. As a thought, we are often short on drinks.
