Megaherbivores and small burrowing mammals commonly coexist play important functional roles in grassland ecosystems worldwide. The interactive effects of these two groups herbivores shaping the structure function are poorly understood. In North America's central grasslands, domestic cattle (Bos taurus) have supplanted bison (Bison bison), now with prairie dogs (Cynomys spp.), a keystone rodent. Understanding ecological relationships between their independent is essential to understanding...
Abstract Kentucky bluegrass, a nonnative species, has invaded rangelands in the United States and is currently present most across Northern Great Plains. Despite its accelerated expansion, consequences of bluegrass on diversity native plant species ecosystem services remain largely unknown. We synthesized available data related to how it affects services. found that invasion may bring negative services, such as pollination, habitat for wildlife alteration nutrient hydrologic cycles, among...
Ecosystem-services scholarship has largely focused on monetary valuation and the material contributions of ecosystems to human well-being. Increasingly, research is calling for a deeper understanding how less tangible, nonmaterial values shape management stakeholder decisions. We propose framework that characterizes suite sociocultural phenomena rooted in key social science disciplines are currently underrepresented ecosystem-services literature. The results from three example studies...
Farmers and ranchers depend on annual forage production for grassland livestock enterprises. Many regression machine learning (ML) prediction models have been developed to understand the seasonal variability in grass production, improve management practices, adjust stocking rates. Moreover, decision support tools help farmers compare practices develop forecast scenarios. Although numerous individual studies growth, modeling, prediction, economics, related are available, these technologies...
Wind erosion is a major resource concern for rangeland managers because it can impact soil health, ecosystem structure and function, hydrologic processes, agricultural production, air quality. Despite its significance, little known about which landscapes are eroding, by how much, when. The National Erosion Research Network was established in 2014 to develop tools monitoring assessing wind dust emissions across the United States. Network, currently consisting of 13 sites, creates...
Abstract Measurements of aeolian sediment transport support our understanding mineral dust impacts on Earth and human systems assessments process sensitivities to global environmental change. However, sample design principles are often overlooked in research. Here we use high‐density field measurements mass flux across land cover types examine size power effects detecting change transport. Temporal variances were 1.6 10.1 times the magnitude spatial for six study sites. Differences...
For nearly a century, invasive annual grasses have increasingly impacted terrestrial ecosystems across the western United States. Weather variability associated with climate change and increased atmospheric carbon dioxide (CO<sub>2</sub>) are making even more difficult challenges of managing grasses. As part special issue on impacts soil water conservation, topic is being addressed by scientists at USDA Agricultural Research Service to emphasize need for additional research future studies...
Predicting forage biomass yield is critical in managing livestock since it impacts stocking rates, hay procurement, and marketing strategies. Only a few prediction studies on pasture rangeland exist despite the need. Therefore, this study focused developing methodology through remote sensing satellite imagery (multispectral bands) climate data, employing open-source software technologies. Biomass ground truth data were obtained from local pastures, where Kentucky bluegrass predominant...
Abstract Transect‐based monitoring has long been a valuable tool in ecosystem to measure multiple attributes. The line‐point intercept (LPI), vegetation height, and canopy gap methods comprise set of core methods, which provide indicators condition. However, users often struggle design sampling strategy that optimizes the ability detect ecological change using transect‐based methods. We assessed sensitivity each these transect length, number, interval 1‐ha plots determine: (1) minimum...
Spatial disparities in rangeland conditions across Kazakhstan complicate field-based assessments of livestock-carrying capacity (LCC), a critical metric for the country’s food security and economic planning. This study developed geospatial (GLCC) modeling framework to quantify LCC spatio-temporal dynamics at Oblast level, by integrating satellite-derived data on vegetation, water resources, terrain with situ measurements. By providing ground-truth observations contextual detail, measurements...

ABSTRACT The current reality of population growth, resource scarcity, and climate change requires resilient agroecosystems to sustain food production protect the environment. This manuscript reflects a combined effort speakers at 2017 C6 Forage Grazinglands Division Symposium, which was titled “Resiliency in Grazinglands.” symposium brought together representing diverse cross‐section forage systems across United States. Each speaker discussed resilience‐related topics from their specific...
To achieve agroecosystem conservation strategies while balancing the needs of people who live and work across rural landscapes, it is critical to understand what need improve sustain their quality life well-being. Research that designed connect social-ecological dynamics, landscape change, human impacts well-being ecosystem health well-suited inform land management decision-making for agricultural production policies. We asked livestock producers, public resource managers, recreation users,...
The Long-Term Agroecosystem Research Network launched the LTAR Agricultural Performance Indicator Framework to evaluate how agricultural innovations perform relative sustainable intensification goals in five domains: Environment, Productivity, Economic, Human Condition, and Social. Here we describe our progress plans for measuring performance of on rangelands. We present a method outcomes management against site-specific benchmarks, which can be applied grazinglands worldwide. typically...
Aeolian processes are fundamental to arid and semi-arid ecosystems, but modeling approaches poorly developed for assessing impacts of management environmental change on sediment transport rates over meaningful spatial temporal scales. For model estimates provide value, flux that encapsulate intra- inter-annual variability needed. Further, it is important quantify communicate transparent uncertainty users. Here, we present a wind erosion dust emission parameterized rangelands using...
