Climate Change in Grasslands, Shrublands, and Deserts of the Interior American West: A Review and Needs Assessment
Year of Publication
2012
Publication Type
Recent research and species distribution modeling predict large changes in the distributions of species and vegetation types in the western interior of the United States in response to climate change.
Is Proactive Adaptation to Climate Change Necessary in Grazed Rangelands?
Year of Publication
2012
Publication Type
In this article we test the notion that adaptation to climate change in grazed rangelands requires little more effort than current approaches to risk management because the inherent climate variability that characterizes rangelands provides a management environment that is preadapted to climate change.
Ecological restoration using EBIPM
Year of Publication
2012
Publication Type
When managing rangeland impacted by weeds, land managers often encounter plant communities where remnant desired vegetation is very scarce. When rangeland is this degraded, simply controlling weeds with the expectation that desired plants will be released from competition and return to dominate the site over time might not be adequate.
Preemergent Control of Medusahead on California Annual Rangelands with Aminopyralid
Year of Publication
2012
Publication Type
Medusahead (Taeniatherum caput-medusae [L.] Nevski), the most problematic invasive grass on many California rangelands, is difficult to control selectively in grasslands. Prescribed burning, grazing, and herbicides have been tested with some success but are not practical in all situations.
Predicting the Occurrence of Downy Brome (Bromus tectorum) in Central Oregon
Year of Publication
2012
Publication Type
Where the nonnative annual grass downy brome proliferates, it has changed ecosystem processes, such as nutrient, energy, and water cycles; successional pathways; and fire regimes. The objective of this study was to develop a model that predicts the presence of downy brome in Central Oregon and to test whether high presence correlates with greater cover. Understory data from the U.S.
Temporal variability in California grasslands: Soil type and species functional traits mediate response to precipitation
Year of Publication
2012
Publication Type
Plant communities on infertile soils may be relatively resistant to climatic variation if species in these communities have "stress-tolerant" functional traits that limit their ability to respond to climate.
Effects of Ungulate Herbivory on Aspen, Cottonwood, and Willow Development Under Forest Fuels Treatment Regimes
Year of Publication
2012
Publication Type
Herbivory by domestic and wild ungulates can dramatically affect vegetation structure, composition and dynamics in nearly every terrestrial ecosystem of the world.
Trajectories of change in sagebrush steppe vegetation communities in relation to multiple wildfires
Year of Publication
2012
Publication Type
Repeated perturbations, both biotic and abiotic, can lead to fundamental changes in the nature of ecosystems, including changes in state. Sagebrush steppe communities provide important habitat for wildlife and grazing for livestock. Fire is an integral part of these systems, but there is concern that increased ignition frequencies and invasive species are fundamentally altering them.
Grassland Response to Herbicides and Seeding of Native Grasses 6 Years Posttreatment
Year of Publication
2012
Publication Type
Herbicides are the primary method used to control exotic, invasive plants. This study evaluated restoration efforts applied to grasslands dominated by an invasive plant, sulfur cinquefoil, 6 yr after treatments. Of the five herbicides we evaluated, picloram continued to provide the best control of sulfur cinquefoil over 6 yr.
