Arizona boasts a diverse forest resource, from the high plateaus in the north to the “sky islands” in the south. Ponderosa pine, mixed-conifer, and pinyon-juniper forests surround the Grand Canyon, which is visited by millions of tourists from all over the world. Near Tucson, one can take a 27-mile drive from valley to mountain top that crosses vegetation zones equivalent to those found driving from Mexico to Canada. Arizona’s forests include some areas, such as the “cypress thicket” that are unique to the state. Because Arizona forests have high scenic, habitat, watershed and timber values, it is important to track their condition.

Inventory and monitoring efforts conducted by RMRS Forest Inventory and Analysis present a systematic compilation of forest statistics of the state. A report titled Arizona's Forest Resources, 2001-2014, presents a summary of the most recent inventory data available for Arizona's forest lands. Beginning in 2001, Annual Inventories began in the state using a new sampling design called the mapped plot design.
