Leigh leads policy efforts related to wildlife conservation. Since joining the WWF family in 2001, Leigh’s work has focused heavily on wildlife crime, marine species conservation, and spearheading WWF’s engagement in CITES (Convention on International Trade in Endangered Species) and the International Whaling Commission. She has played a key role in our efforts to combat illegal tiger trade and to ensure the survival of wild tigers through improved international and U.S. policies, and is currently leading the WWF network’s efforts to phase out tiger farms. She was a core member of the WWF network’s Stop Wildlife Crime campaign, which helped to secure unprecedented global and U.S. leadership to end poaching and wildlife crime, as well as WWF’s campaign to save Mexico’s critically endangered vaquita porpoise. Leigh remains committed to ending the threat posed by bycatch and entanglement in fishing gear to the world’s whales, dolphins and porpoises – the same threat that has driven the vaquita to the brink of extinction.
