What We Do

International Wildlife Conservation is the international program of the National Wildlife Federation. With over 30 years of experience, the International Wildlife Conservation program combines expertise in the fields of natural resource economics, remote sensing and GIS, international law, and tropical ecology to advance market-based solutions and public policy to eliminate the loss of tropical forests around the world.

We promote “zero deforestation” agriculture production in the tropics, focusing on the commodities that have the greatest impacts on forests and wildlife, such as beef, leather, soy, palm oil, and biomaterials. Our work also focuses on advancing strong and comprehensive international agreements that protect forests and our climate.

Who We Are

Barbara Bramble

She serves on the International Board of the Forest Stewardship Council and is the immediate past Chair of the Roundtable on Sustainable Biomaterials, the global multi-stakeholder initiative which set voluntary standards for biofuels and other biomaterials that meet robust voluntary standards for social and environmental safeguards.
