Working together to strengthen and support noxious weed management efforts in Montana.

Burning & Re-Vegetation

Burning

Weed burning can be used as a method of thinning decadent plant material to enhance other treatment options. In some instances, fire alone will give weeds an advantage over native plants. If you do decide to burn off the duff, most counties require a burning permit prior to a burn. More research is needed to determine whether fire is a viable weed control practice.

Re-vegetation

Competitive desirable plants are an important part of successful integrated management of weed infestations because these plants occupy sites and use resources that weeds would otherwise use for growth and reproduction. In addition, desirable plants offer a benefit to the land owner. Unfortunately, weed infestations on highly degraded sites have no desirable plants to re-establish after weed control. These sites need revegetation.

There are a number of conditions that must be addressed to insure successful establishment of desirable plants. Weeds must be controlled, as young seedlings of native or non-invasive plants do not have much chance of survival when they compete with well-established weeds. There needs to be a seed bed in which desirable plants can establish, and this can be accomplished by cultivation, a no-till rangeland or grassland drill, or an herbicide application.

The plant species used for revegetation must be carefully selected to meet site conditions, climatic conditions, weed management objectives, and land use objectives. Broadcast seeding or using a drill is a method that can be used to get seeds into the soil. Timing of seeding is important to take advantage of available soil moisture and weed control, which is usually late fall or early spring. Finally, follow-up management should be designed to help the desirable plants and hurt the weeds. This could include mowing, herbicide application, or grazing by animals to target weeds.

When it comes to re-vegetation, it is imperative to control the weed problem first to give the native grasses and forbs a competitive advantage. Depending on the density and species of the infestation, not all sites will require re-vegetation. Contact local weed professionals for technical assistance or re-vegetation recommendations for your area.
