ancient redwoods. Land purchased by the League is generally donated to California State Parks, which the organization helped found, or to the National Park Service for permanent protection of the redwoods, as well as public enjoyment and education. The League also provides gifts to establish and grow regional preserves and parks, many of which are open to the public. For example, the League established the Purisima Creek Redwoods Open Space Preserve which is part of the Midpeninsula Regional Open Space District (Midpen) in the San Francisco Bay Area. Forest restoration With less than five percent of the ancient redwood forest remaining, the League is leading efforts to restore old-forest characteristics to young redwood forest stands. In a partnership with the National Park Service and California State Parks called Redwoods Rising, the League is working to restore tens of thousands of acres in Redwood National and State Parks, including in the heavily-logged Mill Creek watershed in Jedediah Smith Redwoods State Park. Approximately one-third of giant sequoia groves were partially or heavily logged. Restoration of these forests, helping them to achieve more old-growth characteristics, is an important component of their conservation. Educational programs The League provides numerous educational programs and resources to help K-12 students learn about redwoods forests in the classroom and on field trips. These programs give students the opportunity to learn STEM subjects from real-world examples, to be inspired to protect the forests, and to discover career opportunities in scientific research, park interpretation, and forest management. The League provides many educational resources and curriculum materials directly to teachers and partners with other organizations to extend their reach, such as by providing educational grants. Memorial Groves In 1921, Boone and Crockett Club member Dr. John C. Phillips donated $32,000 to purchase land and create the Raynal Bolling Memorial Grove in the Humboldt Redwoods State Park. That same year, the Stephen T. Mather – William Kent Grove was also established in the same park. Since 1921, the League has established over 1000 redwood memorial groves, in more than thirty of California's redwood parks. One grove is named after Newton B. Drury, who served as executive director of the league as well as serving as the fourth director of the National Park Service. He served in the league's leadership during most of the period from 1919 to 1978. Another grove is named after Drury and his brother Aubrey. The League continues to
