Japanese brome, Russian knapweed, spotted knapweed, and leafy spurge are invasive, non-native weeds in the northern prairies of the central United States. Because they reproduce by seed, destroying the seed with fire may be one way to control these plants. Knowing the fire characteristics that will kill the seeds is important to using this method of control.
The invasive species cheatgrass, Bromus tectorum, has been linked to increased fire frequency, reduced livestock weight gains and plant diversity, and degraded wildlife habitat in the Intermountain region of the western United States.
Grasshoppers in the northern Great Plains periodically experience population outbreaks. While insecticides are available to help control these outbreaks, prescribed burning and livestock grazing, alone or in combination, may offer range managers another method of control.
Patch burn grazing management is prescribed burning and grazing practice that allows livestock and wildlife to select a diet from both burned and unburned vegetation. Differences in forage quality between the burned and unburned areas can affect where animals graze.
Prickly pears are native plants that provide food and habitat for wildlife. However, they can reduce forage and increase livestock injury when there are too many of them. Plains prickly pear is adapted to fire, re-growing from seeds, roots, and pads, but fire can also kill plants.
