Sonoran scrub oak grows in semiarid, lower elevation chaparral, pinyon-juniper (Pinus-Juniperus spp.), shrub deserts, oak woodlands, ponderosa pine (P. ponderosa) and riparian communities of the Southwest.

The abundance of tamarisk (Tamarix ramosissima and related species) along the San Pedro and Gila River flood plains varies with differences in stream flow regimes.

Predicting the potential behavior and effects of wildland fire is an essential task in fire management. Mathematical surface fire behavior and fire effects models and prediction systems are driven in part by fuelbed inputs such as load, bulk density, fuel particle size, heat content, and moisture of extinction.

Creosote bush occurs throughout the Mojave, Sonoran, and Chihuahuan deserts.
