The costs of wildland fire in the United States are enormous, not only in terms of the financial impacts of fire suppression and post-fire rehabilitation of property and ecosystems, but also in terms of loss of lives, impacts on physical health of nearby communities, effects on local and regional economies from losses of revenue, and the impacts of cascading events such as landslides and flooding. Wildland fire management has become even more difficult because of increasingly dry conditions in some areas of the country and the expansion of the urban-wildland interface, among other factors. Within the federal government, for example, more than 50% of the Forest Service's annual budget was dedicated to wildland fire in 2015, up from 16% in 1995.
