Invasive Plants

Balance in the desert ecosystem is threatened by many invasive plants. Sahara Mustard is perhaps best known, but there are many others that are equally problematic.


  Sahara Mustard

Sahara mustard is an invasive non-native weed that is a significant threat to our desert plants and wildflowers. It is also a fire hazard. Use these resources to identify the plant to stop its spread.

Here is a list of other invasive plants found around the Morongo Basin and in the Mojave Desert.  Click each one to find a comprehensive guide on how to recognize and fight these invaders.  Many thanks to Pat Flanagan for creating these very helpful guides.

UPDATE!  A new invasive threat has appeared in the lower desert, in the Anza Borrego area. While it's apparently not yet found in the Morongo Basin, keep a lookout for Volutaria - "A new and noxious plant (that) threatens Southern California."  Read this brochure from the University of California Cooperative Extension for photos and details.
