Sempervirens Fund
Sempervirens Fund, originally established in 1900 as Sempervirens Club, is California's oldest land conservation organization. Founder Andrew P. Hill's goal was to preserve the old-growth forest that became Big Basin Redwoods State Park, the first California state park in 1902. Dedicated to preserving the forest ecology of the majestic coast redwoods, Sequoia sempervirens, all of the Fund's resources are focused on a single "bio-region"; the Santa Cruz Mountains, immediately adjacent to the San Francisco Bay Area population centers.
The Sempervirens Fund strategy is to buy up land and then transfer it to state or local parks departments to create parks or expand existing parks and ensure permanent public access. The group has also worked to establish conservation easements and trail linkages between parks and coastal marine preserves. They have saved more than 24,000 acres (85 km²) in the creation and expansion of redwood parklands.
