Melissa Groo is a wildlife photographer, writer and conservationist. She believes that photography can be both fine art and a powerful vehicle for storytelling and education, and considers herself a “wildlife biographer” as much as a wildlife photographer. Passionate about ethics in nature photography, Groo is represented by Nat Geo Creative, a contributing editor to Audubon magazine and an Associate Fellow with the International League of Conservation Photographers. She advises the National Audubon Society on ethical photography, and has also counseled National Wildlife magazine and NANPA (North American Nature Photography) on guidelines for ethical wildlife photography. She also serves as a member of NANPA’s Ethics Committee. In 2017, Melissa received the Katie O'Brien Lifetime Achievement Award from Audubon Connecticut, for demonstrating exceptional leadership and commitment to the conservation of birds, other wildlife and their habitats. She also received the NANPA 2017 Vision Award, given to a photographer every two years in recognition of early career excellence, vision and inspiration to others in nature photography, conservation and education.
