Fire and Rangelands
Long-term frequent fire and cattle grazing alter dry forest understory vegetation
Year of Publication
2024
Publication Type
Understanding fire and large herbivore interactions in interior western forests is critical, owing to the extensive and widespread co-occurrence of these two disturbance types and multiple present and future implications for forest resilience, conservation and restoration.
Managing Medusahead Using Dormant Season Grazing in the Northern Great Basin
Year of Publication
2023
Publication Type
The invasive annual grass, medusahead, infests rangelands throughout the West, from the Columbia Plateau to the California Annual Grasslands and the Great Basin.
Grasshopper abundance and offtake increase after prescribed fire in semi-arid grassland
Year of Publication
2023
Publication Type
Background
Fire modulates herbivore dynamics in open ecosystems.
Fire needs annual grasses more than annual grasses need fire
Year of Publication
2023
Publication Type
Sagebrush ecosystems of western North America are experiencing widespread loss and degradation by invasive annual grasses. Positive feedbacks between fire and annual grasses are often invoked to explain the rapid pace of these changes, yet annual grasses also appear capable of achieving dominance among vegetation communities that have not burned for many decades.
A Case for Adaptive Management of Rangelands’ Wicked Problems
Year of Publication
2023
Publication Type
Sagebrush-steppe restoration has long been seen as a wicked problem—each case has multifaceted problems with no universal solutions—and thus managers have had to adopt adaptive management techniques to meet ever-changing landscape demands.
The impacts of wildfires of different burn severities on vegetation structure across the western United States rangelands
Year of Publication
2022
Publication Type
Large wildfires have increased in western US rangelands over the last three decades. There is limited information on the impacts of wildfires with different severities on the vegetation in these rangelands.
Ventenata ( Ventenata dubia ) Response to Grazing and Prescribed Fire on the Pacific Northwest Bunchgrass Prairie
Year of Publication
2022
Publication Type
The exotic annual grass ventenata ( Ventenata dubia L.) is raising concern as it rapidly invades multiple ecosystem types within the United States, including sagebrush steppe, ponderosa pine forests, woodlands, and much of the Palouse and Pacific Northwest Bunchgrass Prairie (PNB).
A geographic strategy for cross-jurisdictional, proactive management of invasive annual grasses in Oregon
Year of Publication
2022
Publication Type
On the Ground: Invasive annual grasses pose a widespread threat to western rangelands, and a strategic and proactive approach is needed to tackle this problem. Oregon partners used new spatial data to develop a geographic strategy for management of invasive annual grasses at landscape scales across jurisdictional boundaries.
Repeated fire altered succession and increased fire behavior in basin big sagebrush–native perennial grasslands
Year of Publication
2020
Publication Type
The structure and composition of sagebrush-dominated ecosystems have been altered by changes in fire regimes, land use, invasive species, and climate change. This often decreases resilience to disturbance and degrades critical habitat for species of conservation concern. Basin big sagebrush (Artemisia tridentata ssp.
