Amy Meyer was a key figure in the creation of a huge national park centered around San Francisco’s Golden Gate — a park that includes everything from Alcatraz Island, a redwood forest, a dozen beaches spread along a dramatic coastline, 140 miles of trails, 758 historic buildings covering more than 128 square miles, an area more than 2½ times the size of San Francisco. Last year it attracted 14.9 million visitors.

“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.”

"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.

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.

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.

The Golden Gate National Parks Conservancy has been working toward expanding the waterfront Alcatraz Embarcation Plaza at Pier 31, the launching point for the Alcatraz ferry, since at least 2017. The Parks Conservancy is partnering with commercial real estate agency Maven Properties to find an operator for a new restaurant or cafe space in the updated plaza.

More than 420 guests voyaged to Alcatraz to attend the 22nd annual Golden Gate National Parks Conservancy "Trails Forever" fundraising gala on October 19, raising $1.1 million in the process for projects such as park maintenance, the construction of a new welcome center near Pier 31 and youth education and leadership programs.
