Citizens for a Redwood National Park (CRNP)
This organization was established on February 16, 1965 in Arcata, California. The CRNP was for the establishment of a Redwood National Park, but wanted to represent the local voice of the communities that would be directly affected by the establishment of a park. They especially felt that sections of Redwood Creek should be included in the territory for the National Redwood Park.
Redwood Park and Recreation Committee
This committee consisted of owners and investors of the lumber industries in the area. They sought to create a park that had a balance between land for recreational use and land for industrial use. The committee felt that the tracts that should be saved were those that held the most recreational potential (i.e. rafting, hiking, camping, etc.).
Although founded early on, the Save-the-Redwoods League remained a powerful voice throughout the decades for establishing parks to protect the Redwoods. During the 60s they acquired many pieces of land that would eventually become the various state and national Redwood Parks.
The Sierra Club
The Sierra Club has been involved in the establishment of multiple National Parks and has been present in the creation of some important environmentally minded legislation. They too took notice of the fight for the Redwoods and advocated for their own Redwood National Park plan.
