The incidence and intensity of unintended wildfires in Arizona increases annually as a result of increasing temperatures, decreasing precipitation and snow, and woody plant invasion. Although prescribed fires can often have positive ecological effects , wildfires tend to have devastating effects of native plants and animals and water resources, as well as human life and property. Choosing species with low resin content, high moisture content (e.g. cacti, succulents, and deciduous shrubs), and a higher likelihood to drop leaves (e.g. deciduous shrubs and trees) can provide fire resistance to vulnerable systems .
