Yosemite is a refuge for pollinators, such as bees, butterflies and hummingbirds, which play an essential role in healthy ecosystems but are experiencing worldwide declines due to habitat loss. Even in the park’s protected landscape, many pollinator-friendly plants are losing ground to invasive grasses, meadow fragmentation and other factors.

In 2017, building on the success of a 2016 donor-funded project, crews continued working to reverse that trend. More than 1,000 volunteers, interns and youth group participants worked with park staff to treat 16 acres of non-native invasive plants from meadows around Yosemite Valley. They also collected hundreds of thousands of native seeds, and restored the meadows with pollinator-friendly native plants, such as milkweed and lupine.

Your gift will helped visitors and volunteers develop meaningful connections with the natural world while working to save Yosemite’s native pollinators. See what makes pollinators special in the Yosemite Nature Notes “Monarchs and Milkweed” episode:

Project Notes

The monarch butterfly population has decreased 80% from the 20 year average, mostly from the loss of its host plant, the milkweed. Monarch butterflies, once one of the most prolific and renowned international migratory animals, is now a candidate for the Endangered Species Act. Yosemite, as a protected landscape, is a refuge to native pollinators.
