Spatial dynamics of ecosystem service flows: a comprehensive approach to quantifying actual services Spatial dynamics of ecosystem service flows: a comprehensive approach to quantifying actual services
Recent ecosystem services research has highlighted the importance of spatial connectivity between ecosystems and their beneficiaries. Despite this need, a systematic approach to ecosystem service flow quantification has not yet emerged. In this article, we present such an approach, which we formalize as a class of agent-based models termed “Service Path Attribution Networks” (SPANs)...

Tourism values for Mexican free-tailed bat (Tadarida brasiliensis mexicana) viewing Tourism values for Mexican free-tailed bat (Tadarida brasiliensis mexicana) viewing
Migratory species provide diverse ecosystem services to people, but these values have seldom been estimated rangewide for a single species. In this article, we summarize visitation and consumer surplus for recreational visitors to viewing sites for the Mexican free-tailed bat (Tadarida brasiliensis mexicana) throughout the Southwestern United States. Public bat viewing opportunities are...

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...

Modelling ecosystem service flows under uncertainty with stochiastic SPAN Modelling ecosystem service flows under uncertainty with stochiastic SPAN
Ecosystem service models are increasingly in demand for decision making. However, the data required to run these models are often patchy, missing, outdated, or untrustworthy. Further, communication of data and model uncertainty to decision makers is often either absent or unintuitive. In this work, we introduce a systematic approach to addressing both the data gap and the difficulty 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...
Effects of stream flow intermittency on riparian vegetation of a semiarid region river (San Pedro River, Arizona) Effects of stream flow intermittency on riparian vegetation of a semiarid region river (San Pedro River, Arizona)
The San Pedro River in the southwestern United States retains a natural flood regime and has several reaches with perennial stream flow and shallow ground water. However, much of the river flows intermittently. Urbanization-linked declines in regional ground-water levels have raised concerns over the future status of the riverine ecosystem in some parts of the river, while restoration...
