In the 1944, the League acquired 4,280 acres for Jedediah Smith Redwoods State Park. In 1945, the League and the Garden Club of America raised money to create the 5,000-acre National Tribute Grove in that same park honoring World War II service members. In 1948, dawn redwoods ("Metasequoia glyptostroboides"), thought to be extinct were discovered in China and the League funded scientist Ralph Chaney's trip to investigate.
