Protect Alpine Meadows from Invasive Plants – 2017

Rangers and volunteers remove invasive plants from Yosemite’s high country meadows to protect native wildflowers.

Invasive grasses and flowers threaten Yosemite’s high-elevation meadows, where they out-compete native flora for valuable resources. If left untreated, such plants can throw entire ecosystems out of balance, reducing food and habitat availability for rare amphibians, pollinators and other animals.

Previous support from Conservancy donors led to the discovery and documentation of numerous invasive plants at Yosemite’s high elevations. This year, crews will focus on restoring alpine meadows by eliminating isolated populations of non-native plants growing above 7,000 feet. With help from volunteers, citizen scientists and a stewardship intern, crews will remove an estimated 50 acres of non-native flora, including velvet grass, one of the park’s most threatening species. This project stops the spread of invasive plants, preserves alpine habitat, and engages volunteers and visitors in resource management.

Your support restores Yosemite’s mountain meadows, ensuring native plants and animals can thrive in their high-altitude homes.

Project Notes
Rangers and volunteers remove invasive velvet grass from Yosemite’s high country meadows to protect native wildflowers.

A decade ago, high elevation areas were considered immune to invasive plants because conditions were too harsh. We now know montane to alpine ecosystems are indeed vulnerable to invasion. Tuolumne and Merced are the highest priorities for treatment because of their remoteness and the high quality habitat at risk. If we do not treat them now, we could lose high elevation habitat to these invaders.
