Defining Sustainability in the Greater Yellowstone Ecosystem

The Greater Yellowstone Ecosystem: challenges for regional ecosystem management.

An adaptive management approach is necessary but not sufficient to address the long-term challenges of the Greater Yellowstone Ecosystem (GYE). Adaptive management, in turn, has its own particular challenges, of which we focus on two: science input, and stakeholder engagement. In order to frame our discussion and subsequent recommendations, we place the current management difficulties into thei...

Interdisciplinary Problem-Solving: Next Steps in the Greater Yellowstone Ecosystem

The Greater Yellowstone Ecosystem, a 7.6-million-hectare region in the Central Rocky Mountains of the United States, is used to illustrate both the challenges and means to improve problem solving in the natural resources arena. The challenges in this world-famous region are contextual (rapid change, growth, pluralism, complexity, state/federal conflicts, and lack of a common perspective), insti...

Temporal, Spatial, and Environmental Influences on the Demographics of Grizzly Bears in the Greater Yellowstone Ecosystem

During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded in range. Understanding temporal, environmental, and spatial variables responsible for this change is useful in evaluating what likely influenced grizzly bear demographics in the GYE and where future management efforts might benefit conservation ...

Ranchland Ownership Change in the Greater Yellowstone Ecosystem, 1990–2001: Implications for Conservation

Most of the public lands protected for conservation in the western United States are surrounded by working landscapes of various types, typically in agro-pastoral ownership and use. How these working landscapes evolve over time and how their inhabitants respond to various conservation goals will in large measure determine the success or failure of efforts to maintain regional biodiversity. This...
