This issue brief reports on the mechanics of and lessons learned from a conservation incentive program focused on the gopher tortoise. Its aim is to inform the successful design and implementation of other candidate programs emerging throughout the southern forests and greater United States. The Switzer Foundation is funding a pilot demonstration project to test the feasibility of the project concept. Read a summary and download the report

Sad tales of our failures in society to be adaptable, remarkable stories of the intricate ways in which natural organisms have survived and thrived for billions of years on an unpredictable planet, and hopeful examples of how all sorts of people, organizations, corporations and bureaucracies have learned to be adaptable.

Several studies have implicated lead poisoning in deaths of the endangered California condor. A study published this year found lead poisoning was the primary cause of death in juvenile and adult condors from 1992 to 2009. A 2010 study analyzed three to four months of lead levels using condor feathers and found much higher and more frequent exposures than blood draws suggested, said Myra Finkelstein, an environmental toxicologist at UC Santa Cruz, who conducted the study. Still other work tied the chemical composition of lead found in poisoned birds with that of ammunition.

The study, "Connecting Natural Landscapes Using a Landscape Permeability Model to Prioritize Conservation Activities in the United States," appears in the journal Conservation Letters. Authors include David Theobald of CSU, Kenyon Fields and Michael Soulé from Wildlands Network and Sarah Reed from the Wildlife Conservation Society. Read the full story

The overall objective of this field study is to quantify cougar ecology in the Greater Yellowstone Ecosystem. Specific goals are to:

“People once had the pleasure of spotting flying squirrels gliding through the forests and visiting their porches at night in the San Jacinto Mountains, but not anymore,” said Shaye Wolf, climate science director at the Center for Biological Diversity. “It’s a tremendous loss. The flying squirrel needs the immediate protections of the Endangered Species Act to ensure that it doesn’t suffer any more declines.”
