Native forb response to sulfometuron methyl on medusahead-invaded rangeland in Eastern Oregon

Creator:: Louhaichi, Mounir, Carpinelli, Michael F., Richman, Lesley M., and Johnson, Douglas E.
Abstract:: Medusahead [Taeniatherum caput-medusae (L.) Nevski], a non-native, winter-annual grass (Poaceae), has invaded rangelands throughout the western USA. Medusahead is an aggressive competitor that crowds out native plants and reduces forage for wildlife and livestock. Sulfometuron methyl is a sulfonylurea herbicide used to control medusahead, but its effect on non-target native...

Spring, summer and fall use by cattle and big game on foothill rangelands

Creator:: Miller, Richard F.
Abstract:: The objectives of this study were to evaluate environmental factors influencing use of several plant communities by cattle, elk and deer; determine under story production by plant species and the amount utilized by cattle, elk and deer in certain plant communities; evaluate the interactions of range use between cattle, elk...

Ecology and Management of Rangeland Weeds

Creator:: Oregon State University. Agricultural Experiment Station
Abstract:: The encroachment of alien weeds onto western rangelands is one of the most perilous and perhaps least recognized problems facing land managers today. Oregon rangelands are under siege from ever-increasing numbers and distribution of exotic weeds. They threaten Oregon's economy and environmental quality by reducing livestock forage, wildlife habitat, watershed...

A model to predict the bacterial quality of a rangeland stream

Creator:: Biskie, Howard A
Abstract:: Grazing cattle usually have access to streams as a source of drinking water. A model was developed for the personal computer to predict the bacterial quality of these streams. The model estimates the number of organisms that enter the stream by the direct deposit of feces and by runoff from...

Are Early Summer Wildfires an Opportunity to Revegetate Exotic Annual Grass–Invaded Plant Communities?

Creator:: Davies, Kirk W., Nafus, Aleta M., and Johnson, Dustin D.
Abstract:: 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...

Mowing Wyoming Big Sagebrush Communities With Degraded Herbaceous Understories: Has a Threshold Been Crossed?

Creator:: Davies, Kirk W., Bates, Jonathan D., and Nafus, Aleta M.
Abstract:: 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,...

Medusahead Invasion Along Unimproved Roads, Animal Trails, and Random Transects

Creator:: Davies, Kirk W., Nafus, Aleta M., and Madsen, Matthew D.
Abstract:: Medusahead (Taeniatherum caput-medusae [L.] Nevski), an exotic annual grass, is rapidly spreading and causing ecological damage across the western United States. Because this exotic plant occupies vast areas and because management resources are limited, it is critical that land managers prioritize where they direct treatment and monitoring efforts. Identifying where...

Exotic annual grass invasion alters fuel amounts, continuity and moisture content

Creator:: Davies, Kirk W. and Nafus, Aleta M.
Abstract:: Many exotic annual grasses are believed to increase wildfire frequency to the detriment of native vegetation by increasing fine fuels and thus, creating a grass-fire cycle. However, information on differences in fuel characteristics between invaded and non-invaded plant communities is lacking, or is based mainly on speculation and anecdotal evidence....
