Christine (Chris) Dragisic

Managing Director, Global Policy – National Audubon Society

As Managing Director for Global Policy at the National Audubon Society (Audubon), Chris is keen to draw on her policy and programmatic experience to advance the efforts of the US National Committee. She has been working at the intersection of conservation and climate change for more than two decades. At the World Bank and at Conservation International, she designed and implemented programs in biodiversity conservation, protected areas management, sustainable agriculture and forestry, climate change, and more. While serving in the climate change office of the US Department of State, Chris developed and advanced policy efforts to combat deforestation, improve land use, set and implement ambitious climate targets, and improve the transparency of reporting. Now at Audubon, she is leading the organization’s engagement on global conservation and climate policy, working with stakeholders from the local level all the way through national institutions.

As a member of the US National Committee (hereafter, USNC) Executive Committee, Chris will bring both her professional qualifications and the expertise of colleagues at Audubon. Audubon (a recently reinstated member of IUCN) brings deep scientific and programmatic expertise, backed by a 120-year history of working with diverse constituencies throughout the US and the hemisphere.

Chris will draw on this experience to bring to the USNC a keen sense of how to increase support for, and the relevancy of, IUCN’s work in these complex times. She also hopes to draw on a diverse network of the types of contacts and partners critical to IUCN’s work, ranging from local level institutions to multinational companies and government leaders. Finally, she brings to this work a true passion for conservation and climate action in the US and beyond.

Jennifer is currently serving on the USNC Executive Committee and is nominated for a third two-year term.
