The last record of the Leafcutter Bee (Trachusa gummifera) in Marin County was in 1977. That is, until the One Tam Community Science Program had a documented sighting of it nearly 47 years later.

This week we hear from Sara Leon Guerrero, a manager of the One Tam Community Science Program through the Golden Gate National Parks Conservancy. Sara tells us how One Tam is leading the way in bridging ecological data gaps, implementing long-term monitoring efforts, and fostering curiosity and community participation.
