Desert Botanical Laboratory, Tumamoc Hill, Tucson, Pima County, AZ

Significance: The Desert Botanical Laboratory is important as the first center for the study of desert plant ecology, and for the outstanding scientists who paved the way for further development in the study of plants and ecology. The site itself is important also because of the numerous ancient Indian sites and artifacts still intact on the hill and in the surrounding area. The Desert Botanical Laboratory was designated a National Historic Landmark in 1965, and was registered in 1975, and is listed in the National Register of Historic Places. In 1981 the complex was designated as a State Natural Area by the Arizona State Parks Board.
