Removing Invasive Plants from Yosemite

Invasive plants are the single largest threat to Yosemite’s beautiful native wildflowers. Invasive species use up valuable resources and can eventually replace native plant populations, throwing entire ecosystems out of balance.

By disrupting ecosystems, invasive plants can displace wildlife that are dependent on native plants for food and shelter. Every year brings new invaders, with more than 200 currently identified — 33 in the past three years alone.

This project expanded the park’s survey area with the help of volunteers and technology. A smartphone app will allow professional and volunteer surveyors to collect information about invasive plants.

Using the survey data, scientists can quickly identify and eliminate invasive plants. Podcasts and videos teach visitors about the negative impact of bringing outside firewood (and invasive weeds) into the park.
