The recommendations presented in the report are based on Defenders’ analysis of the opportunities and constraints for renewable energy development in the southern San Joaquin

Conservation Hotspots at Risk on the Arizona Border

The 2,000-mile u.s.-mexico border passes through several conservation hotspots, including two in Arizona, the Sonoran Desert and the Sky Islands. These are areas important to endangered and threatened species and other wildlife and in which the United States and Mexico have significant investments in conservation lands and collaborative projects.

Conservation Hotspots at Risk in the Texas Borderlands

The 2,000-mile u.s.-mexico border passes through several conservation hotspots where the United States and Mexico have significant investments in conservation lands and collaborative projects to protect endangered and threatened species and other wildlife. Texas has two hotspots: the Big Bend area along the Rio Grande to the west and the Lower Rio Grande Valley on the Gulf Coast in the east.

Conservation Lands and Collaborations at Risk in the California Borderlands

The 2,000-mile u.s.-mexico border passes through several conservation hotspots, including the coastal area of southern California and northern Baja California, Mexico, known as the Californias. Seventy-two percent of the border here is already blocked by fencing. Adding even more would have devastating consequences for wildlife, people and binational conservation efforts and investments.

Buoying Washington State's Response to Abandoned and Derelict Vessels

The Puget Sound is home to a diverse marine ecosystem and several endangered species, including southern resident orcas and their primary prey, chinook salmon. The sound is also home to an active boating community, which comes with an unfortunate downside: abandoned and derelict vessels. Owners who have either lost interest or can no longer afford to operate and maintain their vessels often leave them to sit and deteriorate. Over time, decay and storms set many abandoned vessels adrift. These derelict vessels wash ashore or sink and are a major source of pollution harmful to orcas, salmon and other marine wildlife.

Connecting the Dots: Orcas, Salmon and Toxic Chemicals in the Salish Sea

After decades of studying southern resident orcas, we now know much about their behavior, culture—the learned behaviors unique to this population—and what they need to survive. We also have answers to some of the most pressing questions about the population’s decline, including the impact of toxic chemicals found in the orcas’ food supply.

Bringing El Tigre Home: Jaguar Recovery in the U.S. Southwest

Defenders has been working to conserve jaguars in Mexico and the United States for more than a decade. In Mexico, we played a major role in creating, supporting and guiding the Northern Jaguar Project, which works to sustain the most northern known breeding population of jaguars in the Americas.

Section 4(D) Rules: The Peril and the Promise

This white paper evaluates every section 4(d) rule issued under the Endangered Species Act through May 2016. It also describes Defenders' position on the use of those rules and recommendations for better ways to implement the rules.
