Invasive plants

Over the years many non-native plants have become established in our area. This page offers general information on invasive plant species of concern in the Sedona area. We welcome public input regarding the identification and control of invasive plants and weeds.

Bufflegrass.
Native to Africa, this species was introduced into the U.S. in the 1930s as livestock forage and for erosion control. Over the years it has proliferated and become common in Arizona. Buffelgrass prefers sandy soils and arid climates. If allowed to grow unchecked, it can rapidly cover large areas resulting in suppression of desirable plants and can creates a potential grass fire hazard.

Although though Sedona is on the northern boundary of the Buffelgrass range and above the desired elevation, isolated areas of Buffelgrass plants have been found within the city limits. Small areas are easy to control with spot treatments of Roundup and/or manually removing, bagging, and disposing of individual plants.

Onion weed.
This is another species native to Africa and the Mediterranean/Western European regions that has recently spread to Australia and North America. It is not a true onion but the leaves are very similar in appearance. Onion Weed does not invade well-established lawns but is an issue in newly disturbed construction areas or roadside right-of-ways. If allowed to prosper it produces large amounts of seeds and can out compete desirable plant species.

The city has worked with the USDA Animal and Plant Health Protection Service to identify and control infestations. Manual removal of individual plants and/or applications of Roundup herbicide are the preferred methods of control.
