Cacti & Succulents of the Sonoran Desert
The Sonoran Desert is synonymous with cacti, and a wide diversity of species can be seen here.
Flora of Upland Arizona
Various forms of pine-oak woodland cover the slopes of many of Arizona's mountain ranges. The precise range of species varies with location, elevation and aspect. In south-eastern Arizona, in a a similar way to the region's fauna, various Mexican plant species of the Sierra Madre reach their northern limit, whilst an equal number of Rocky Mountain species reach their southern limit on cool north-facing mountain slopes.
Herbaceous Flora of the Sonoran Desert
The Sonoran Desert occupies the central and south-western third of Arizona. It is lower in elevation than the Chihuahuan & Mojave deserts and hence has a milder climate, although snow can fall in extreme winters.
Trees & Shrubs of the Sonoran Desert
The Sonoran Desert is best known for cacti and its spring wildflowers but also has some emblematic trees and shrubs, from the Creosotebush to the Ironwood, Mesquites and Ocotillo.
