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 However, the data required to run these models are often patchy, missing, outdated, or untrustworthy.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...
