The Enduring Mystery of Synchronized Acorn Booms
Some years are great for acorns but during some the crop fails entirely. Walt Koenig takes us through an informative and engaging presentation about California’s oaks. During his talk, you’ll learn about the issues that affect the variation and synchrony of acorn production in the trees around us. His presentation draws from data collected for the California Acorn Survey, encompassing more than 1,000 trees at 25 sites spread across California. You’ll gain knowledge about booms and busts in acorn production, as well as the implications for animals that depend on acorns for food in an ever-changing world.
This webinar explores paleo valleys and their potential to help manage California’s flood waters and store it for future droughts. Our conversation is moderated by Bay Nature editor in chief Victoria Schlesinger together with journalist Erica Gies, author of our Winter 2022’s cover story “Capturing the Flood in California’s Ancient Underground Waterways,” and UC Davis professor emeritus of hydrogeology Graham Fogg.
A Year with the Urban Gray Fox
Join the Fox Guy, Bill Leikam, as he takes us through an informative and engaging presentation about the gray fox (Urocyon cinereoargenteus). Although gray foxes are frequently spotted in the Bay Area, very little is known about them, especially their behavior. His presentation will begin with an overview of the gray fox’s general ecology, then will weave the science with personal stories about the foxes he studied over the course of five years.
Nature Journaling with John Muir Laws
Join artist, author, and educator John Muir Laws for a virtual walk in the woods to explore how to observe with the eyes of a naturalist, discovering and celebrating the signs of the Bay Area season in a nature journal.
Join us for a deep dive on mushrooms and enjoy just watching or pick up your pencil to sketch!
Living on Public Lands
Join us for a conversation about public lands and their increasing role as a refuge for the unhoused during California’s affordable housing crisis. It’s indisputable that more people are living both legally and illegally on public lands and that it’s an issue communities and agencies are already facing. Who is living on public lands? Why are they living there? And what is the impact on the land?
Q&A on don’t feed the coyotes
After a century of extirpation, coyotes returned to the green spaces of San Francisco in the early 2000s. Twenty years later, a thriving population of Canis latrans resides in the city’s parks and forests. The documentary don’t feed the coyotes observes several years in the intertwined lives of these urban animals. It centers around a three-year-old coyote, fondly named Scout, and her territorial challenger, the scientifically dubbed 15F. Chronicling their lives through two starkly different researchers observing them, it’s about humans, the natural world, and the lines we’ve drawn between the two. And of course, not feeding the coyotes.
Bay Nature hosted an advanced screening of the film don’t feed the coyotes which can be viewed at dontfeedthecoyotes.com. Following the screening of the film, Bay Nature hosted a Q&A with filmmaker Nick Stone Schearer alongside Bay Area self-taught naturalist, Janet Kessler, and wildlife ecologist with Presidio Trust, Jonathan Young.
Tales of Urban Whales
Learn about the whales, dolphins, and porpoises of the San Francisco Bay Area! Join marine mammal biologist Bill Keener as he presents the results of The Marine Mammal Center’s latest studies. This is a story of environmental change in the bay, as these fascinating animals have adapted to life in our urban waters. Here’s your chance to learn from a local scientist about the lives of whales, the difference between porpoises and dolphins, where to see them, and what you can do to help in the research.
An Inside Look at Bay Area Bobcats
Join conservation photographer Sarah Killingsworth, a Marin County-based California Naturalist, for an intimate look at bobcats in the Bay Area. In this webinar you will learn more about this elusive species as well as how to ethically approach bobcat photography, what gear Sarah uses, the zen of wildlife photography and tips for coexisting with bobcats in your neighborhood (yes, in the Bay Area, you probably have them).
People, Science, and Nature at One Tam
Join One Tam’s Community Science Program Manager Lisette Arellano in conversation with author and science journalist Mary Ellen Hannibal about how community science is fueling conservation on Mount Tamalpais. Hear from Lisette about three of One Tam’s community science programs: the Marin Wildlife Picture Index Project, the Bioblitz series, and the Tamalpais Bee Lab. Mary Ellen explores the connection between individual action and regional, state-wide, and global efforts.
