Alongside nearly 1.9 million members and supporters, NPCA has been fighting to protect America's national parks for over a century. NPCA is an independent, nonpartisan voice working to protect and strengthen America’s favorite places Since 1919, the National Parks Conservation Association has been the independent, nonpartisan voice working to strengthen and protect America's favorite places. With more than a 1.6 million members and supporters beside us, we work to protect and preserve our nation's most iconic and inspirational places for present and future generations. We celebrate the parks— and work tirelessly to defend them — whether on the ground, in the courtroom or on Capitol Hill. From our national headquarters in Washington, D.C., and 27 locations nationwide, we call on our program and policy experts, committed volunteers, staff lobbyists, community organizers and communications specialists to inform and inspire the public and to influence decision makers to ensure that our national parks are well protected.
