Time-based nitrogen availability and risk of Taeniatherum caput-medusae (L.) Nevski invasion in central Oregon

Creator:: Stubbs, Michelle M.
Abstract:: During the last century, fire suppression, grazing, and climate change have caused sagebrush grasslands to be altered in both function and form; juniper and sagebrush dominate the landscape at the expense of herbaceous plants. Management efforts to reduce juniper and sagebrush overstory in order to enhance herbaceous components of the...

Detecting medusahead (Taeniatherum caput-medusae (L.) Nevski) using high frequency, sequential, globally positioned digital images

Creator:: Ndzeidze, Stephen Koghan
Abstract:: Invasive plant species are expanding and transforming vegetative communities across Oregon and throughout the United States. Over the past three decades remote sensing, geographic information system (GIS), and Global Positioning System (GPS) technologies have been integrated to detect and map the distribution of noxious rangeland plants. This study developed low-cost...

Landscape-Scale Rehabilitation of Medusahead (Taeniatherum caput-medusae)- Dominated Sagebrush Steppe

Creator:: Sheley, Roger L., Vasquez, Edward A., Chamberlain, Anna-Marie, and Smith, Brenda S.
Abstract:: Producers facing infestations of invasive annual grasses regularly voice the need for practical revegetation strategies that can be applied across broad landscapes. Our objective was to determine the potential for scaling up the single-entry approach for revegetating medusahead-infested rangeland to broader, more heterogeneous landscape-scale revegetation of winter annual grass–infested rangeland....

Mycological Maintenance of Rangelands and the Impacts of a Thatch Forming Invasive Annual Grass (Taeniatherum caput-medusae)

Creator:: Hovland, Matthew
Abstract:: Arbuscular mycorrhizal fungi (AMF) may exert profound influences on ecosystem resilience and invasion resistance in western North American sagebrush steppe and other arid rangeland plant communities. Maintenance of plant community structure through ecological feedbacks such as facilitation of nutrient cycling and uptake by host plants, physical and chemical contributions to...

Field study of competition between medusahead (Taeniatherum caput-medusae ssp. asperum (Simk.) Melderis) and squirreltail (Elymus elymoides (Raf.) Swezey)

Creator:: Clausnitzer, David
Abstract:: Medusahead (Taeniatherum caput-medusae ssp. asperum (Simk.) Melderis) is a Eurasian annual grass that infests large areas of U.S. rangelands, dominating former bunchgrass/shrub sites. Squirreltail (Elymus elymoides (Raf.) Swezey) is a native perennial grass that has demonstrated the ability to establish in stands of medusahead. A study conducted on two sites...

Medusahead (Taeniatherum asperum Nevski) : a review and annotated bibliography

Creator:: Hilken, Thomas O. and Miller, Richard F.
Abstract:: Medusahead (Taeniatherum asperum Nevski), a winter annual native to the Mediterranean region of Eurasia, has infested several million acres of rangeland in the northwestern United States. It has been estimated carrying capacity for domestic livestock on infested ranges has been reduced 75 percent. The review is a condensed summarization of...

Relationship of nitrogen level to medusahead, Taeniatherum asperum (Sim.), competition with wheatgrass and silica content

Creator:: Brown, Dean Allen
Abstract:: Studies were conducted to determine the competitive ability of medusahead, Taeniatherum asperum (Sim.), for nitrogen when grown in association with perennial range grass species. The method used to determine this competitive ability was to compare the dry weight, percent nitrogen, and total nitrogen of medusahead and perennial wheatgrass species growing...

Vegetation changes of communities containing medusahead (Taeniatherum asperum (Sim.) Nevski) following herbicide, grazing, and mowing treatments

Creator:: Turner, Robert Bruce
Abstract:: Studies were conducted from 1962 to 1966 to investigate the effectiveness of several practices in manipulating medusahead (Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated ecosystems by releasing competition in favor of perennial grasses. Several herbicide treatments were evaluated for selective control of medusahead and cheatgrass (Bromus tectorum L. )...

Establishment of subterranean clover (Trifolium subterraneum L.) on medusahead, (Taeniatherum asperum (sim.) Nevski) infested ranges in western Oregon

Creator:: Vigil, Frederick Rudolph
Abstract:: An experiment was conducted to determine the best method to establish subterranean clover on medusahead infested ranges in Western Oregon. Secondary objectives of this study were to determind the effects of management treatments on (a) subterranean clover density, (b) density of medusahead and other vegetation, and (c) yield of subterranean...
