Speaker: Rachel Kesel Among the rare vegetation types found on Mount Tamalpais, serpentine barrens present plants with some of the harshest soil conditions for growth. For much of the year it appears that these areas of pretty blue rock and soil are indeed barren. However, several rare annual plants make a living in this habitat, including some endemic to the Mount Tam area. In addition to serpentine barrens, adjacent chaparral and grasslands host rare perennial species equally as tough as…

Speaker: Obi Kaufmann The greatest tool we have in defending California's natural world, its biodiversity and its ecology, is an informed citizenry. Public policy is beginning to respond to an new upwelling of desire, as evidenced by hugely popular land trust organizations and non-governmental organizations to protect, restore and safeguard the whole, living portfolio of our unique and endemic systems across the Golden State. Transcending political polarizations, Californians are coming together to address long-standing, environmental remediation projects on a local…

Speaker: Ted Kipping Trees co-evolved with a rich ecological support system over many eons. As people have migrated into our increasingly densely populated and denatured cities, we have attempted to bring some of the trees with us - not always successfully. With a tad more insight and understanding, we can do a lot better. Come see for yourselves. The Rhizosphere - Tree Anatomy Below Ground shares the amazing insights and lab work of the late Dr Alex Shigo, a giant…

Join us for a “natural pruning” demonstration by Leslie Buck, who specializes in pruning landscapes over time so naturally you can’t tell they’ve been touched. Leslie will demonstrate easy-to-learn techniques you can apply in your gardens by using pre-cut branches of native plants. She will also give a brief reading from her garden memoir, "Cutting Back: My Apprenticeship in the Gardens of Kyoto,” published by Timber Press, describing her adventures with garden craftsmen in some of the most wild (rather…

Speaker: Erica Spotswood In this report, we investigate how integrating components of oak woodlands into developed landscapes — “re-oaking” — can provide an array of valuable functions for both wildlife and people. Re-oaking can increase the biodiversity and ecological resilience of urban ecosystems, improve critical urban forest functions such as shade and carbon storage, and enhance the capacity of cities to adapt to a changing climate.

Speaker: Heath Bartosh Despite previous research and study, the original distribution, subsequent radiation, and genetic identity of the northern California black walnut (Juglans hindsii) remains a source of considerable perplexity and debate. This confusion is confounded by the perception that some northern California black walnut trees may be hybrids with other native or non-native Juglans species. To get a clearer understanding of the northern California black walnut’s historic and current distribution as well as the rate of hybridization throughout a…

San Bruno Mountain State and County Park is a habitat island amidst a sea of urbanization, and is home to a variety of rare, threatened, and endangered plant and wildlife species - some of which occur only in this park. This talk will outline recent efforts to map and catalog rare plant populations, describe the critical habitat requirements for the four protected butterfly species found in the park, and discuss the ongoing efforts for habitat management for the benefit of…
