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.
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.
This bi-annual newsletter is prepared by the co-chairs of the Species Survival Network Shark Working group, Alejandra Goyenechea (Defenders of Wildlife) and Rebecca Regnery (Humane Society International). The newsletter provides a summary of the latest international and regional shark news, and an analysis of the latest actions and regulations regarding sharks.
North American species feeling the effects of climate change
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.
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.
Defenders provides you with our co-sponsored newly-published book on Freshwater rays (Potamotrygonidae), where you will find exquisite details of the latest research from Carlos Lasso (Humboldt Institute from Colombia) on these magnificent and forgotten species in the mega-diverse countries of South America. Freshwater rays have been a topic of discussion in CITES since 2004 and, in 2016, Colombia and Brazil listed some species of the Family in Appendix III.
Defenders of Wildlife’s Predator-Resistant Enclosure Program works with rural residents and small livestock owners in southwest Florida to build predator-resistant pens or to retrofit existing enclosures. Diligent use of a predator-resistant enclosure is an effective way to keep domestic animals safe from predators.
