From that commitment sprang an effort to savethe great Redwoods of California and the Petrified Forest of Arizona, the great bird rocks of the Aleutian Islands and the Tongass of Alaska.
Privately-funded efforts to save this regal bird from extinction had been underway for some time at that point, and the federal government began its own efforts in 1966 with the passage of the Endangered Species Preservation Act, the precursor to the more comprehensive Endangered Species Act (ESA) of 1973.
