Join Federation President & CEO Collin O’Mara as he reflects on this year’s conservation accomplishments and the science, policies, and strategies guiding us into our 90th year. From our defense of public lands to our focus on reconnecting people with nature, the National Wildlife Federation is dedicated to transforming common interests into action benefiting wildlife, habitat, and people.
A former Ranger Rick kid, Collin O’Mara serves as President and CEO of the National Wildlife Federation, America’s largest conservation organization, representing 52 state and territorial affiliates and over seven million members. Under his leadership, the Federation drives bold, inclusive efforts to recover America’s wildlife, while conserving and restoring our lands and waters, confronting the climate crisis, advancing environmental justice, and connecting children with nature. A respected voice in Congress, he was an architect of the bipartisan coalition that passed the Great American Outdoors Act, securing permanent funding for the Land and Water Conservation Fund.
Collin is a leading proponent of “big tent” collaborative conservation that unites Sovereign Tribal Nations, hunters and anglers, labor unions, and environmental justice advocates to drive durable, landscape-scale conservation. He has replicated this model repeatedly to secure historic investments in natural resources and climate and most recently to defeat an ill-advised effort to sell public lands.
Collin’s conservation work runs deep, from serving as a Clean Tech Strategist for the City of San José, California to the Federation's work protecting monarch butterflies, reconnecting wildlife corridors, and supporting conservation ballot initiatives. Previously, as Delaware's Secretary of Natural Resources, he led trailblazing community-driven restoration and resilience projects. He was a Marshall Scholar at Oxford, a University Fellow at the Maxwell School, and a Presidential Scholar at Dartmouth. When not working, he can be found loving every minute in nature with his three young daughters and wife Krish.
