49 Creosote bush shrubland Creosote bush (Larrea tridentata) dominates scrublands in the Mojave, Sonoran, and Chihuahuan deserts throughout the Southwest. Each desert community has a unique shrub and herbaceous component that accompanies creosote bush, and many have a cactus component as well. Historically, these desert communities burned very infrequently due to low fuel presence. Due to fire exclusion and heavy grazing, they are now invading surrounding grasslands or are being invaded by nonnative grasses that change the fire regime. This is a regional fuelbed that spans all 3 desert types. 310,320,330,340 6 166,224 2,3 4 2
