Brian Mealor, Associate Professor and Director of the Sheridan Research and Extension Center, UW, discusses strategic opportunities where land managers can intervene to move the needle on cheatgrass. It describes the level of invasion and management strategies applicable to each. Then, Mike Pellant, Ecologist, Retired BLM, discusses post-fire opportunities, cheatgrass die-off areas, and the myths and realities of dormant season targeted grazing.

Reducing cheatgrass has been a primary research topic and goal of ecological restoration for over 50 years. Our work examined published studies between 1946 and 2012 to identify how a broad range of control methods influence cheatgrass and perennial grass abundance. Based on this assessment, we identify obstacles encountered in achieving desired restoration and clarify what research is needed to develop improved mechanistic control strategies. Jeremy Maestas, Ecologist, USDA-NRCS, and Tom Monaco, Ecologist, USDA-ARS and USU, present.

Conversion of native rangelands to cheatgrass, and subsequent impacts on wildfire regimes, are one of the most challenging threats to sagebrush ecosystems today. The widespread and complex nature of the problem and lack of clarity on effective management actions are often barriers to implementing meaningful treatments and practices to reduce risks. Although there is no silver bullet, combining cheatgrass reduction treatments with promotion or restoration of perennial vegetation in an integrated, adaptive management framework can move the needle toward maintenance and recovery of functioning ecosystems. This webinar series will provide information on integrated management approaches using specific strategies and proven tools.

There are two key takeaways from the research: 1) conifer removal is an effective tool for increasing sage grouse populations, and 2) sage grouse populations may take several years to respond to management actions because they are long lived and have lower reproductive output compared to other game birds.
View brief.
Study findings include:
- From 2011-2017, the extent of conifer cover in sagebrush country decreased by 1.6%. Human management efforts are responsible for 2/3 of the total reduction; the other 1/3 is due to wildfires.
- Previous estimates suggest that conifer cover in sagebrush country is growing by 0.4%-1.5% annually, which means that our efforts are keeping pace with conifer encroachment but that more needs to be done.
- Public/private partnerships are successfully reducing conifers in highly targeted priority watersheds, such as in northwest Utah.
- The maps also show that woodlands are still expanding into many sagebrush landscapes. Continued partnership efforts are needed to strategically conserve priority shrublands.
