Oregon; basins; landscapes; rangelands; spatial data
Abstract:
... •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. The geographic strategy considers annual and perennial herbaceous cover along with site ...
... •Adaptive management should explicitly involve stakeholders, emphasize multiple iterations of identifying and prioritizing outcomes, and tightly link science-informed monitoring to decision-making benchmarks for effective feedback loops.•Short-term monitoring procedures should be simple, quick, and based on consistent methods that are focused on locations where meaningful change is expected or unc ...
... •A workshop focusing on invasive annual grass management in sagebrush steppe was held on December 14 and 15, 2020•The workshop was attended by 250 participants with over 30 presenters.•This special issue of Rangelands includes papers authored by the presenters on the topics covered in the workshop. ...
agroecosystems; collective action; decision making; rangelands; social change; sustainable agriculture
Abstract:
... • Integrated social-ecological research is crucial for the development and assessment of sustainable agricultural production that supports health and well-being for producers, rural communities, and agroecosystems. • One challenge for integration is that commonly used concepts like ecosystem services do not represent all environmental processes that support or degrade health and well-being. • Soci ...
... •The application of small unmanned aerial systems (sUAS) has expanded to include livestock management, however the effects of sUAS disturbance on domestic horses (Equus calibus) has not been well documented.•We developed an ethogram to classify and record horse behaviors and changes in response to disturbance using a DJI Phantom 4 Pro sUAS by monitoring horse behavior at 5 second intervals from 3 ...

decision making; range management; rangelands; space and time
Abstract:
... •Rangeland management has entered a new era with the accessibility and advancement of satellite-derived maps.•Maps provide a comprehensive view of rangelands in space and time, and challenge us to think critically about natural variability.•Here, we advance the practice of using satellite-derived maps with four guiding principles designed to increase end user confidence and thereby accessibility o ...
... •Monitoring courses, offered at universities and through professional training, are critical to successfully collecting and applying rangeland monitoring data.•Instructors can meet course objectives by carefully considering course content, the target audience, delivery approaches, evaluation mechanisms, and training for new instructors.•Shared principles and practices taught in monitoring courses ...
data collection; land management; landscapes; rangelands
Abstract:
... •Adaptive land management requires monitoring of resource conditions, which requires choices about where and when to monitor a landscape.•Designing a sampling design for a monitoring program can be broken down in to eight steps: identifying questions, defining objectives, selecting reporting units, deciding data collection methods, defining the sample frame, selecting an appropriate design type, d ...

adaptive management; concrete; cost effectiveness; data quality; ecosystems; information management; quality control; rangelands
Abstract:
... •High-quality rangeland data are critical to supporting adaptive management. However, concrete, cost-saving steps to ensure data quality are often poorly defined and understood.•Data quality is more than data management. Ensuring data quality requires 1) clear communication among team members; 2) appropriate sample design; 3) training of data collectors, data managers, and data users; 4) observer ...
data collection; ecological function; rangelands; remote sensing; vegetation
Abstract:
... •Interpreting Indicators of Rangeland Health and other well-designed qualitative assessments are useful for understanding ecological function and can be used to prioritize areas for monitoring, restoration, or management changes. When completed by experienced, trained multidisciplinary teams, qualitative assessments provide reliable information about ecological processes and are repeatable across ...
... •Monitoring supports iterative learning about the effectiveness of management actions, information that can help managers plan future actions, facilitate decision-making, and improve outcomes.•Adaptive monitoring is the evolution of a monitoring program in response to new management questions; new or changing environmental or socioeconomic conditions, improved monitoring methods, models, and tools ...
... •Sustainable beef is a socially responsible, environmentally sound, and economically viable product that prioritizes planet, people, animals, and progress. Beef sustainability requires awareness of the complex relationships among these three pillars.•In practice, sustainability to beef farmers and ranchers is about taking care of the animals, land, and water, while being a good neighbor and commun ...
... •Sustainable ranch management must consider not only impacts of grazing management on range condition (ecological sustainability) but also on cattle production relative to overhead costs (economic sustainability) and on biodiversity (biological sustainability).•Rates of growth and reproduction in herbivore populations are determined by access to sufficient high-quality forage and concomitant optim ...
Artemisia; fire severity; fire spread; fire suppression; fuel moisture index; grasses; rangelands; risk; wildfires
Abstract:
... •Wildfires and incidents of large fires have increased substantially in the past few decades, in part from increases in fine, dry fuels. Fine fuel management is needed, and grazing is likely the only tool applicable at the scale needed to have meaningful effects.•Moderate grazing decreases wildfire probability by decreasing fuel amount, continuity, and height and increasing fuel moisture content. ...
... •Kangaroo rats occur exclusively in arid environments of western North America, where they often function as ecosystem engineers and keystone species.•These rodents can exist on a diet of seeds without drinking free water.•Kangaroo rats evade attacks from their primary predators, owls and snakes, using split-second gymnastic-like maneuvers.•Kangaroo rat activities, such as digging, altering soil s ...
... •Invasive annual grasses on sagebrush rangelands are negatively impacting land uses and values ranging from forage for grazing livestock to native plant diversity, wildlife habitat, and human safety via associated increases in the wildfire footprint.•In December 2020 a diverse group of managers, scientists, and government officials held a symposium to discuss existing and emerging options for amel ...
