Transition Zone
Quick Summary
The Transition Zone, also known as the Central Highlands, is a physiographic region in Arizona, United States. It lies between the Colorado Plateau to the north and the Basin and Range Province to the south. This zone is characterized by a diverse landscape, including separated plateau blocks, rugged peaks, and rolling uplands.1
Climatically, the Transition Zone varies widely over short distances due to its varied relief. It represents an ecological border between the low deserts and the higher, forested elevations, blending elements of both. For instance, desert plants like the Spanish bayonet can be found alongside junipers typical of higher altitudes. Much of Arizona's humid area is located within this zone and the adjacent southern edge of the Colorado Plateau.21
