Speaking with Parks Conservancy Program Manager Sara Leon Guerrero, CBS News highlights how the re-detection of the San Francisco leaf-cutter bee is a hopeful sign and conservation success.

One Tam, a partnership among the National Park Service, California State Parks, Marin Water, Marin County Parks, and the nonprofit Golden Gate National Parks Conservancy, ensures “the long-term health of Mt. Tamalpais,” the conservancy said. The species, “endemic to the Bay Area,” has been documented less than 100 times, the conservancy said.

"This is hopeful news in a time when we are hearing a lot about trouble for insects, especially pollinators," expressed Sara Leon Guerrero, Community Science Program Manager at the Parks Conservancy.

“Now, our scientists can learn more about this special species’ ecology,” the Parks Conservancy said in a social media post. “It’s hopeful news for Mt. Tamalpais’ biodiversity, and for other species that could still be out there.”
