Invasive Plants

A small saguaro surrounded by tall brown grass.
For invasive plant management in the Sonoran Desert, buffelgrass is the archenemy. Over 90% of our invasive plant management efforts are directed against buffelgrass

Invasive plants know no boundaries. They can affect native plants and wildlife, change the fire regime, endanger the ecosystem, make the park less attractive for visitors, and spread beyond park borders to adjacent land.

Whether they arrived by wind or water, bird or boots, invasive plants are a threat in Saguaro National Park.
