Hiking the Sky Islands and the Arizona Trail

Terri Gay is a long-time Tucson hiker, rock climber and lover of desert backcountry.

Terri will share photos and adventures from this trek in the sky islands and across the state.

Guy McPherson
Threats to Biological Diversity in the Sky Islands:
Can an Informed Citizenry Overcome Society?
Guy McPherson
February 15, 2006
Development of a just, sustainable human enterprise requires us to acknowledge and account for the explicit links between environmental protection, social justice, and the human economy. This will require contributions from virtually every segment of society, and, while striving for global ideals, we must start with local actions. McPherson describes historical and contemporary "drivers" behind relatively coarse-scale ecosystems in the Sky Islands of the American Southwest. Cursory inspection of factors such as fire, livestock grazing, urbanization, biological invasions, and regional climate change indicate the important role played by the current generation of decision-makers in creating a just, sustainable future. McPherson provides a general template and some specific examples that may facilitate the transition to sustainability.

The Sky Island Legacy: An Introduction to the Region and Its Major Conservation Issues
Peter Warshall

With an academic background in biology and anthropology, Warshall works globally with highly diverse people and ecosystems. His expertise includes natural history, natural resource management (especially watersheds, wastewater, and wildlife), conservation biology, biodiversity assessments, environmental impact analysis, and conflict resolution and consensus building between divergent economic and cultural special interest groups. He has worked in Africa for various organizations and in Arizona for several Native American tribes and as an adjunct research scientist with the Office of Arid Lands Studies (University of Arizona). Warshall has a special interest in producers of commodities (loggers, farmers, ranchers, fishermen, miners) as they are the link between the materials flows of our economy and the natural world.
In addition to his role as Editor-At-Large with Whole Earth, he is Sky Island Alliance's newest board member and is the founder of Peter Warshall and Associates, a consulting firm specializing in complex economic/ecological systems, especially those that impact water resources and wildlife populations. He has written two major articles on Sky Island ecology and biogeography and is an expert on the Mt. Graham Red Squirrel. He is also the current Research Director on Pinaleno Inventory.
