Restoration of exotic annual grass-invaded rangelands is needed to improve ecosystem function and services.
Increasing plant species richness is generally believed to increase resistance to invasion and increase desired
vegetation. However, the effects of species richness and individual plant life forms in seed mixes used to restore
rangelands invaded by...
Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Successful
revegetation of invaded-plant communities can be prohibitively expensive because it often requires iterative applications of
integrated control and revegetation treatments. Prescribed burning has been used to control medusahead and prepare seedbeds
for revegetation, but burning has...
Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) plant communities with degraded native herbaceous understories occupy vast expanses of the western United States. Restoring the native herbaceous understory in these communities is needed to provide higher-quality wildlife habitat, decrease the risk of exotic plant invasion,...
