Join One Tam as we embark on a new phase of the Tamalpais Bee Lab and become a community scientist!

When: Saturday, May 10, 2025, 11 a.m.-2 p.m.

Where: Lake Lagunitas, Mt. Tamalpais

The Tamalpais Bee Lab, a program of our One Tam partnership, is studying local wild bees in Marin County. We started with inventorying which species were present in the county's public lands. We're now focusing on better understanding local bee communities, gathering information to inform future targeted monitoring, and contributing local data to broader efforts seeking to study and protect native bees. To achieve these goals, this year we are taking part in the California Bumble Bee Atlas, and volunteers can get involved!

The California Bumble Bee Atlas is a collaborative community science effort, coordinated by the Xerces Society of Invertebrate Conservation and California Department of Fish and Wildlife, to track and conserve California’s native bumble bee species and contribute to the global understanding of bumble bee distributions. Learn more about why we're focusing on bumble bees and how it works: cabumblebeeatlas.org

Volunteers can participate in these bumble bee surveys with TBL! You must register in advance here >>

Please note that while you can register for this program on multiple dates at the link above, locations will vary, so please note where each date is taking place. Registrants will receive more information closer to the event. Generally, each survey involves:

1. Visiting a site designated by One Tam agency partners as an area of interest.
2. Searching for bees or their nest sites.
3. Documenting the bees and/or nest sites with high quality photographs.
4. Uploading the photographs and metadata to a portal for identification by experts.
