The University of Arizona holds a truly unique collection of plants from arid and semi-arid climates around the world. Many campus trees are the largest specimens in Arizona and have been designated as Great Trees of Arizona. There are 5 trees on the National Register of Big Trees. The UA Heritage Trees are stately links to the University's past. Several are unique to the entire Southwest; a few were the first of their kinds to be planted in the Western Hemisphere.
