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.

Chaparral Fire Ecology & the Fire Following Plants Around us

In this timely Bay Nature Talk, senior botanist Heath Bartosh delves into chaparral fire ecology, including fire return intervals and climate concerns. Learn how California’s chaparral ecosystems recover from fire, meet some common fire-following plants, and find out where to see fire followers this spring!
