SEPTEMBER 7, THURSDAY, 7:30 PM

Restoring Habitat for San Francisco’s Rare Endemic Manzanitas.

Speaker: Michael Chassé

San Francisco hosts two of the rarest manzanitas in the world: Raven’s Manzanita (Arctostaphylos montana subsp. ravenii) and Franciscan Manzanita (Arctostaphylos franciscana). These endangered species grew together in a distinct maritime chaparral habitat that once covered the serpentine hilltops of San Francisco. Their story is one of loss, salvage, rediscovery, and serendipity. Michael Chassé will share the story of how San Francisco’s rare endemic manzanitas were brought back from the brink of extinction and how current efforts are returning these species to the San Francisco landscape.

Michael Chassé is a vegetation ecologist for the National Park Service at the Golden Gate National Recreation Area, where he has coordinated natural areas stewardship and rare plant monitoring for close to 20 years. He is a graduate of San Francisco State University’s Department of Geography. His master’s thesis focused on San Francisco’s rare endemic manzanitas.

OCTOBER 5, THURSDAY, 7:30 PM

Bees, ZomBees, and Citizen Science.

Speaker: Dr. John Hafernik

Concern about threats to honey bees and other pollinators is mounting. The honey bee is not native to the United States, but it is an important pollinator of agricultural crops and the mainstay of commercial and backyard honey production. In the U.S., hive failure rates are increasing as honey bees deal with introduced mites, diseases, pesticides and other stressors. These and other factors also threaten native bees. Recently a new threat to honey bees, the parasitic phorid fly Apocephalus borealis (AKA the Zombie Fly), was discovered in San Francisco. Bees infected by the fly (Zombees) show disoriented zombie-like behavior leaving their hive at night to die under nearby lights. San Francisco State’s John Hafernik will discuss the importance of native bees and honey bees as pollinators, as well as implications of zombie fly parasitism for honey bees in California and beyond. He will also provide information on how the public can get involved in tracking prevalence of zombie fly parasitism across North America through the citizen science project ZomBee Watch (zombeewatch.org).

Dr. John Hafernik is Professor Emeritus of Biology at San Francisco State University and a past President of the California Academy of Sciences. He is also a former president of the American Association for the Advancement of Science, Pacific Division; and of the Pacific Coast Entomological Society. He served as chair of the SF State Biology Department from 1992-2005 and as Interim Director of the SF State Romberg Tiburon Center for Environmental Studies from 2013-2014. John became fascinated with insects and the natural world as a young boy growing up in Texas.

The Ancient Bristlecone Pine trees(Pinus longaeva) are found in the California White Mountains in the Ancient Bristlecone Pine forest, within the Inyo National Forest. Some of these trees are almost 5,000 years old and have survived in a harsh environment at elevations of 10,500 – 11,500 feet above sea level. The bristlecone pine trees have taught us a great deal about past climates. Dr. Edmund Schulman, dendrochronologist and climatologist, was the first to document their longevity in 1953. We will take a detailed look at these fascinating trees.

Mila Stroganoff is a long-time member of CNPS and a Yerba Buena Chapter board member for over 25 years. She is Poster and Book Sales Chair and Programs Co-Chair and wears other hats as needed. She has a piano performance degree in classical music from the Royal Conservatory of Music at the University of Toronto and a biology degree from the College of San Mateo.

NOVEMBER 2, THURSDAY, 7:30 PM (in San Francisco)

Botanical Exploration of Coastal North America of the 18th and 19th Centuries.

Speaker: John Kipping

While immersing ourselves in our native floras, we encounter numerous species whose botanical names commemorate people. Who were Douglas, Clark, Fremont, Menzies, and Eschscholtz? Join the November meeting as we trace the history of botanical exploration of western North America from the mid-1700s through 1855. We shall learn about the oceanic voyages of Bering, Cook, Collnett, Vancouver, Malaspina, de la Perouse, Kotzebue, Beechey, and Wilkes as well as land-based journeys of Lewis and Clark, Douglas, Nuttall, Fremont, Hartweg, Loeb, and Whipple. We will join naturalist and arborist John Kipping as he describes the times and tales of pioneering collectors and botanists.

Residing in the foothills Gold Country, John is a member of the El Dorado Chapter of CNPS with deep roots in the Bay Area. John worked in nature education for nearly 30 years at the Randall Junior Museum, San Francisco Botanical Garden and Audubon Canyon Ranch. After earning an MA in biological sciences at San Francisco State, he became an instructor in the Natural Environment Program of the University of California Extension at Berkeley, Santa Cruz, Davis, and Los Angeles for over two decades and has led nature tours in our western states as well as New Zealand, Ecuador, Baja California, British Columbia and Alaska where he spends summers aboard a small excursion vessel. He has authored over fifty articles about plants and three small books for children.
