What is Cheatgrass? Cheatgrass (Bromus tectorum), is an invasive annual species. This species poses a significant ecological threat to the Southern Great Plains of Texas, particularly in the Rolling Plains Region. Cheatgrass will displace native grasses such as sideoats grama (Bouteloua curtipendula), blue grama (Bouteloua gracilis) and little bluestem (Schizachyrium scoparium). These dominant, perennial, native grasses are key to maintaining soil stability, biodiversity, and forage quality (D’Antonio & Vitousek, 1992; Chambers et al., 2014).
70 Questions Important for Grassland Conservation
Did you know that Grasslands are crucial to global food security, rangeland economies, carbon storage, and a variety of ecosystem services? Did you know that 31-43% of global lands are grasslands?
A Management Priorities Working Group (MPWG) comprised of 11 individuals was tasked with identifying and reviewing the management related documents in order to:
1) Synthesize grassland management goals and challenges.
2) Identify questions and information needed to allow grassland managers to meet their goals within the context of climate change.

Patch Burn Grazing: An Economic Analysis of Pyric Herbivory Rangeland Management by Cow-Calf Producers
Patch-burn grazing is a practice that requires an understanding of the interaction of fire and grazing (pyric herbivory) (for more information check out www.theprairieproject.org). It divides a pasture into pieces/patches, with one burn rotationally each year. It helps control woody plant encroachment and provides high-quality forages. Despite these known benefits, the adoption of this practice by ranchers has been slow and limited. This study focused on the benefits of patch-burn grazing by estimating the costs and long-term economic benefits. Additionally, researchers compared patch-burning to traditional applications of prescribed fire burning fenceline to fenceline or an entire pasture at once with a 3-year fire return interval.
Stability of C3 and C4 Grass Patches in Woody Encroached Rangeland after Fire and Simulated Grazing
In the western portion of the southern Great Plains, grasslands are defined as “southern mixed”, with warm season or C4 mid-grasses being dominant and cool season or C3 short-grasses in less frequent densities. As woody plant encroachment increasingly dominates, the productive warm season C4 grasses begin to decline with less abundance on the landscape and even less productivity. Woody plant dominance also reduces plant diversity eroding heterogeneity in the mixed-grass prairie. Recently, researchers measured the effects of various combinations of spring clipping (mimicked cattle grazing) and prescribed fire treatments over an 8 year period on Texas wintergrass and buffalograss with the overall objective of reducing Texas wintergrass abundance and increasing warm season C4 mid-grass species and diversity.
North American Grasslands Conservation Council – Upcoming Bill
Did you know that grasslands provide vital habitat for a multitude of species which represent the lifeblood of local and regional economies?? That the maintenance of health populations of grasslands species and working lands are critical for rural economies? That grassland and rangeland ecosystems provide essential and significant habitat for mammals, pollinators, reptiles, and other wildlife? Roughly 358,000,000 acres or 85% of the United States is privately owned and serves as an important habitat for 29 grassland bird species!

What is the Value of Native Vegetation Restoration on Oil & Gas Rights-of-Way?
Did you know that there are more than 500,000 miles of oil and gas rights-of-ways in Texas alone? There has been limited information available to evaluate the difference in restoring disturbed lands to native states versus the more traditional use of non-native seeds. Being able to understand the difference along with the ecosystem impacts and the social benefits could create a positive case for vegetation restoration by the oil and gas industry.

CO2 Flux over Burned Honey Mesquite Savanna Rangeland
Prescribed fire is a management practice used to reduce woody plant encroachment on rangeland and maintain native perennial grass diversity and productivity. Prescribed fire effects on CO2 fluxes and their contribution to atmospheric CO2 is not well known. The study below discusses the effect of fire on net ecosystem CO2 flux above Prosopis glandulosa Torr. (honey mesquite) using the Bowen ratio/energy balance method (BREB), and to compare these fluxes to fluxes determined by an empirical model.

Extreme Prescribed Fire during Drought Reduces Survival and Density of Woody Resprouters
Researchers looked at extreme fire conditions during drought in humid subtropical and semi-arid ecoregions that require innovative management strategies that go beyond the traditional restoration and conservation practices. These practices have either been historically ineffective or economically cost-prohibitive at restoring grass-dominated ecosystems following conversion to resprouting shrublands.
