Model performance and output variables for phenological events across land cover types in the Northwestern Plains, 1989-2014 Model performance and output variables for phenological events across land cover types in the Northwestern Plains, 1989-2014
Many aspects of recurring plant developmental events – vegetation phenology – are measured by remote sensing. By consistently measuring the timing and magnitude of the growing season, it is possible to study the complex relationships among drivers of the seasonal cycle of vegetation, including legacy conditions. We studied the role of current and legacy climate, and contextual factors on...
UAV based vegetation classification results and input NDVI, vegetation height, and texture datasets for two Montana rangeland sites in 2018 UAV based vegetation classification results and input NDVI, vegetation height, and texture datasets for two Montana rangeland sites in 2018
Unpiloted aerial system (UAS) flight campaigns were conducted at two rangeland sites in Southwestern Montana during the 2018 growing season to classify vegetation and landcover types. A total of nine flights were conducted at the Argenta site and seven at the Virginia City site. To align images in space and time, we used four-dimensional structure from motion (4D SfM) and continued with...
A Multiscale Index of Landscape Intactness for the Western U.S. A Multiscale Index of Landscape Intactness for the Western U.S.
Landscape intactness has been defined as a quantifiable estimate of naturalness measured on a gradient of anthropogenic influence. We developed a multiscale index of landscape intactness for the Bureau of Land Managements (BLM) landscape approach, which requires multiple scales of information to quantify the cumulative effects of land use. The multiscale index of landscape intactness...

Structured science syntheses to inform decision making on Federal public lands Structured science syntheses to inform decision making on Federal public lands
The U.S. Geological Survey, Bureau of Land Management, and U.S. Fish and Wildlife Service partnered to develop a new type of science product: the structured science synthesis. Structured science syntheses are peer-reviewed reports that synthesize science information about a priority resource management issue on public lands. Structured science syntheses are developed explicitly to...

Synthesis of climate and ecological science to support grassland management priorities in the North Central Region Synthesis of climate and ecological science to support grassland management priorities in the North Central Region
Grasslands in the Great Plains are of ecological, economic, and cultural importance in the United States. In response to a need to understand how climate change and variability will impact grassland ecosystems and their management in the 21st century, the U.S. Geological Survey North Central Climate Adaptation Science Center led a synthesis of peer-reviewed climate and ecology literature...

Antecedent climatic conditions spanning several years influence multiple land-surface phenology events in semi-arid environments Antecedent climatic conditions spanning several years influence multiple land-surface phenology events in semi-arid environments
Ecological processes are complex, often exhibiting non-linear, interactive, or hierarchical relationships. Furthermore, models identifying drivers of phenology are constrained by uncertainty regarding predictors, interactions across scales, and legacy impacts of prior climate conditions. Nonetheless, measuring and modeling ecosystem processes such as phenology remains critical for...

Multiple UAV flights across the growing season can characterize fine scale phenological heterogeneity within and among vegetation functional groups Multiple UAV flights across the growing season can characterize fine scale phenological heterogeneity within and among vegetation functional groups
Grasslands and shrublands exhibit pronounced spatial and temporal variability in structure and function with differences in phenology that can be difficult to observe. Unpiloted aerial vehicles (UAVs) can measure vegetation spectral patterns relatively cheaply and repeatably at fine spatial resolution. We tested the ability of UAVs to measure phenological variability within vegetation...

Is the grass always greener? Land surface phenology reveals differences in peak and season-long vegetation productivity responses to climate and management Is the grass always greener? Land surface phenology reveals differences in peak and season-long vegetation productivity responses to climate and management
Vegetation phenology—the seasonal timing and duration of vegetative phases—is controlled by spatiotemporally variable contributions of climatic and environmental factors plus additional potential influence from human management. We used land surface phenology derived from the Advanced Very High Resolution Radiometer and climate data to examine variability in vegetation productivity and...

Towards an urgent yet deliberate conservation strategy: Sustaining social-ecological systems in rangelands of the Northern Great Plains, Montana Towards an urgent yet deliberate conservation strategy: Sustaining social-ecological systems in rangelands of the Northern Great Plains, Montana
Urgency and deliberateness are often at odds when executing conservation projects, especially as the scale and complexity of objectives increases. The pace of environmental degradation supports immediate and measurable action. However, best practices for adaptive governance and building resilient social-ecological systems call for more deliberate efforts and participatory processes...

Quantifying ecological integrity of terrestrial systems to inform management of multiple-use public lands in the United States Quantifying ecological integrity of terrestrial systems to inform management of multiple-use public lands in the United States
The concept of ecological integrity has been applied widely to management of aquatic systems, but still is considered by many to be too vague and difficult to quantify to be useful for managing terrestrial systems, particularly across broad areas. Extensive public lands in the western United States are managed for diverse uses such as timber harvest, livestock grazing, energy development...

Toward a social-ecological theory of forest macrosystems for improved ecosystem management Toward a social-ecological theory of forest macrosystems for improved ecosystem management
The implications of cumulative land-use decisions and shifting climate on forests, require us to integrate our understanding of ecosystems, markets, policy, and resource management into a social-ecological system. Humans play a central role in macrosystem dynamics, which complicates ecological theories that do not explicitly include human interactions. These dynamics also impact...
