The National Park System is well endowed to commemorate Hispanic contributions to American society. Some 20 national parklands represent America's Hispanic heritage. Some sites remotely display Hispanic contributions to American culture. The National Park System not only preserves the history and contributions of Hispanic Americans, it is also a part of the nation's history. Over the years, the National Park Service has reflected the nation's social history. Among the first Hispanics who influenced the course of the National Parks were:
- George Melendez Wright was born in California in 1904. In 1927, he was hired at Yosemite National Park as assistant park naturalist. Through his studies and insight, the park service moved away from the destruction of predator to the scientific management of park plants, animals and scenery.
