Ecosystem services valuation to support decisionmaking on public lands—A case study of the San Pedro River watershed, Arizona Ecosystem services valuation to support decisionmaking on public lands—A case study of the San Pedro River watershed, Arizona
This report details the findings of the Bureau of Land Management–U.S. Geological Survey Ecosystem Services Valuation Pilot Study. This project evaluated alternative methods and tools that quantify and value ecosystem services, and it assessed the tools’ readiness for use in the Bureau of Land Management decisionmaking process. We tested these tools on the San Pedro River watershed in...

The Colorado Plateau V: research, environmental planning, and management for collaborative conservation The Colorado Plateau V: research, environmental planning, and management for collaborative conservation
Roughly centered on the Four Corners region of the southwestern United States, the Colorado Plateau covers some 130,000 square miles of sparsely vegetated plateaus, mesas, canyons, arches, and cliffs in Arizona, Utah, Colorado, and New Mexico. With elevations ranging from 3,000 to 14,000 feet, the natural systems found within the plateau are dramatically varied, from desert to alpine...
Social values for ecosystem services (SolVES): Documentation and user manual, version 2.0 Social values for ecosystem services (SolVES): Documentation and user manual, version 2.0
In response to the need for incorporating quantified and spatially explicit measures of social values into ecosystem services assessments, the Rocky Mountain Geographic Science Center (RMGSC), in collaboration with Colorado State University, developed a geographic information system (GIS) application, Social Values for Ecosystem Services (SolVES). With version 2.0 (SolVES 2.0), RMGSC has...

KINEROS2/AGWA: Model use, calibration and validation KINEROS2/AGWA: Model use, calibration and validation
KINEROS (KINematic runoff and EROSion) originated in the 1960s as a distributed event-based model that conceptualizes a watershed as a cascade of overland flow model elements that flow into trapezoidal channel model elements. KINEROS was one of the first widely available watershed models that interactively coupled a finite difference approximation of the kinematic overland flow equations...

A GIS application for assessing, mapping, and quantifying the social values of ecosystem services A GIS application for assessing, mapping, and quantifying the social values of ecosystem services
As human pressures on ecosystems continue to increase, research involving the effective incorporation of social values information into the context of comprehensive ecosystem services assessments is becoming more important. Including quantified, spatially explicit social value metrics in such assessments will improve the analysis of relative tradeoffs among ecosystem services. This paper...

Accounting for the ecosystem services of migratory species: Quantifying migration support and spatial subsidies Accounting for the ecosystem services of migratory species: Quantifying migration support and spatial subsidies
Migratory species support ecosystem process and function in multiple areas, establishing ecological linkages between their different habitats. As they travel, migratory species also provide ecosystem services to people in many different locations. Previous research suggests there may be spatial mismatches between locations where humans use services and the ecosystems that produce them...

The use of scenario analysis to assess water ecosystem services in response to future land use change in the Willamette River Basin, Oregon The use of scenario analysis to assess water ecosystem services in response to future land use change in the Willamette River Basin, Oregon
Human pressures on the natural resources of the United States have resulted in many unintended changes in our ecosystems, e.g., loss of biodiversity, habitat degradation, increases in the number of endangered species, and increases in contamination and water pollution. Environmental managers are concerned about broad-scale changes in land use and landscape pattern and their cumulative...

Assessment of goods and valuation of ecosystem services (AGAVES) San Pedro River Basin, United States and Mexico Assessment of goods and valuation of ecosystem services (AGAVES) San Pedro River Basin, United States and Mexico
A consortium of federal, academic, and nongovernment organization (NGO) partners have established a collaborative research enterprise in the San Pedro River Basin to develop methods, standards, and tools to assess and value ecosystem goods and services. The central premise of ecosystem services research is that human condition is intrinsically linked to the environment. Human health and...

Flood hazard awareness and hydrologic modelling at Ambos Nogales, United States–Mexico border Flood hazard awareness and hydrologic modelling at Ambos Nogales, United States–Mexico border
Appropriate land‐use, watershed‐management, and flood‐attenuation plans are critical in the cross‐border urban environment known collectively as Ambos Nogales. This paper summarizes methodologies for predicting the watershed response associated with land‐use change within a spatial and temporal context through the use of a hydrological model in a cross‐border setting. The KINEROS2 model...

Planning for an uncertain future - Monitoring, integration, and adaptation Planning for an uncertain future - Monitoring, integration, and adaptation
The 6.7 billion human inhabitants of the earth have the ability to drastically alter ecosystems and the populations of species that have taken eons to evolve. By better understanding how our actions affect the environment, we stand a better chance of designing successful strategies to manage ecosystems sustainably. Toward this end, the Third Interagency Conference on Research in the...
Using a coupled groundwater/surface-water model to predict climate-change impacts to lakes in the Trout Lake Watershed, northern Wisconsin Using a coupled groundwater/surface-water model to predict climate-change impacts to lakes in the Trout Lake Watershed, northern Wisconsin
A major focus of the U.S. Geological Survey’s Trout Lake Water, Energy, and Biogeochemical Budgets (WEBB) project is the development of a watershed model to allow predictions of hydrologic response to future conditions including land-use and climate change. The coupled groundwater/surface-water model GSFLOW was chosen for this purpose because it could easily incorporate an existing...
