“Our national park system is a dear expression of the idealism of the American people.” -Harry S Truman, during his address at the dedication of Everglades National Park, 1947
Today is the 110th birthday of the National Park Service! On August 25, 1916, President Woodrow Wilson signed legislation creating the National Park Service to "preserve unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations." Over the hundred plus years, we've grown into more than 400 national park sites and many programs that reach communities around the country—and even the world!
Harry Truman understood the importance of National Parks, the conservation of natural resources, and the preservation of historic sites. He helped create National Parks, National Monuments, Historical Parks, and National Memorials; including:
Everglades National Park, Theodore Roosevelt National Memorial Park (now Theodore Roosevelt National Park), consolidated and expanded Grand Teton National Park, Hovenweep National Monument, Effigy Mounds National Monument, Adam’s National Historical Park, Independence National Historical Park, Fort Sumter National Monument, and De Soto National Memorial.
