“…Regardless, it is an indication of the loss of forage value due to V. dubia invasion. Loss of perennial grasses and replacement with annual grasses that become unpalatable early in the growing season result in a loss of nutrients available to cattle and wildlife (Fryer 2017;McCurdy et al 2017).…”

“…In other words, the mass of crude protein and TDN lost from annual grass biomass removal was replaced by that gained from increases in perennial grasses, but not exceeded. Here it is important to keep in mind that even though V. dubia does have comparable nutrient mass, it is reportedly unpalatable to cattle unless it has been processed by pelletizing (McCurdy et al 2017). Nutrients are not available to cattle or wildlife if they are not ingested.…”

“…Ventenata dubia has little value as a forage species early in the growing season (Pavek et al 2011). Any small value is shortlived, as V. dubia becomes unpalatable once it becomes dry (Fryer 2017; but see work by McCurdy et al [2017] on pelletizing V. dubia). Although this invasive annual grass has been present in North America for nearly 70 yr, it has only recently been documented in the Great Plains, where its impacts on ecosystem goods and services, such as forage production and biodiversity, are still being discovered.…”

Ventenata dubia (Leers) Coss is one of several annual grass invaders of the western US. Ventenata dubia is documented reducing the forage availability for livestock and wildlife as well as lowering biodiversity in the Great Basin. This species has recently spread to the Great Plains, where it could bring these impacts with it. We attempt to answer questions on whether or not conservation practices, in this case removal of V. dubia with herbicide, results in recovery of forage resources and biodiversity. We answer these questions by measuring biomass, cover, and nutrient content one year post treatment at eleven sites in Sheridan County, Wyoming, conducted in two years. Perennial grasses have higher crude protein and total digestible nutrients than V. dubia and removal of V. dubia resulted in a positive perennial grass response both years. Further, the differences in pattern of growth between perennial and annual species, with annual grasses quickly senescing early in the year, make perennial grasses a more dependable forage base with higher available nutrients. Interestingly, total biomass and nutrient mass did not change after V. dubia removal due to equal replacement with perennial grasses. Species richness and diversity were unaffected by removal of V. dubia. Our results suggest that managing invasive annual grasses, particularly V. dubia, in the northern Great Plains can improve forage resources for livestock and wildlife while maintaining species diversity. Therefore, proactive monitoring and management efforts to prevent spread should be prioritized in this region.

“…Consequently, it can be tempting to see the nutrient quality of ventenata as a positive for rangeland forage production ( Hart and Mealor 2021 ), as has been the case with cheatgrass ( Young and Allen 1997 ). However, the growth stage and height of the grass complicate cattle grazing, as does the questionable palatability of ventenata ( McCurdy et al 2017 ;Hart and Mealor 2021 ). This means there may only be a brief window of opportunity for cattle to graze ventenata.…”

“…Reasons for low utilization of ventenata are unclear. Low palatability due to texture and timing of grazing have been hypothesized as reasons for low use ( Wallace et al 2015 ;McCurdy et al 2017 ;Ridder et al 2022 ). Because the phenology of ventenata is earlier than native grasses but later than other invasive annual grasses in the region ( James 2008 ;McKay et al 2017 ), some suggest the timing of grazing could impact its use, as well as potential spread with cattle grazing ( Wallace et al 2015 ;Ridder et al 2022 ).…”

Rangeland wildlife ecology and conservation is strongly influenced by domestic livestock systems. Domestic livestock production on rangelands in North America is dominated by ruminant livestock, with beef cattle being the largest industry. Rangeland ruminant livestock production systems are unique in that land/animal managers develop production systems that attempt to optimize the use of limited-nutrition forage bases. This involves the strategic selection of calving/lambing dates to coincide with forage resources and labor limitations. Likewise, the species, breed, and age of animal is selected to be productive in sometimes suboptimal nutrition and environmental conditions. In addition, the role of this industry in the conservation and enhancement of wildlife diversity and ecosystem services is important now and paramount in future management goals. Grazing systems that are unique to the needs of ecosystems are designed to enhance soils, vegetation, and wildlife diversity. In addition, understanding how wild and domestic animals utilize landscapes of varying topography is an ongoing area of research. Continued investigations into how animals use landscapes, grazing distribution/behavior, botanical composition of diets, and dietary strategies will be important in designing management approaches for all animals that are dependent on rangeland resources. The paradigm of sustainable management of livestock systems needs to view herbivory as a tool to manage vegetation for optimal biological integrity and resiliency. Only by the optimization of biological processes within plant communities on rangelands, will managers create systems that benefit both livestock and wildlife.
