To help remove the grass, Pima County Natural Resources, Parks and Recreation has launched "Beat BackBuffelgrass Month," which runs until March 2.
Bufflelgrass takes over the landscape and sucks up all nutrients and water, leaving other plants to die. The grass is also a serious fire risk.
Right now, volunteers are needed to remove it from "A" Mountain, Saguaro National Park, Catalina State Park, Tucson Mountain Park, and Sabino Canyon.
To sign up to volunteer, go to www.buffelgrass.org. If you’d like to host a buffelgrass pull in your own neighborhood, your favorite park, or elsewhere, register a site and it will be added to the list of sites for volunteers to select.
