Petrified Forest was set aside as a national monument in 1906 to preserve and protect the petrified wood for its scientific value. It is recognized today for having so much more, including a broad representation of the Late Triassic paleo-ecosystem, significant human history, clear night skies, fragile grasslands ecosystem, and unspoiled scenic vistas.
Scientific studies are on-going at the park. Paleontologists find new fossils, including new species of plants and animals, each year. Biologists study living plants and animals, including vegetation surveys and reptile, amphibian, and mammal projects. Archeological site monitoring is on-going. Air quality, weather, and seismic monitoring stations constantly generate new data.
