The Association of Partners for Public Lands (APPL) was known for its first 20 years as the Conference of National Park Cooperating Associations (CNPCA), an organization that worked to advance the common purposes of its national park-affiliated members. In November 1997, CNPCA’s members voted to expand their umbrella to include not-for-profit organizations that serve all public land management agencies.

Incorporated in California in 1977, APPL recently celebrated 35 years of serving the public lands community.
