Two major factors affecting wilderness fire regimes and their management are climate variability and surrounding land use. Patterns in climate and housing densities are expected to change dramatically in the next several decades (IPCC 2007; Theobald and Romme 2007) with important implications for fire management and policy (Dombeck et al. 2004). Successful protection and stewardship of wilderness means anticipating how these trends will affect fire regimes in the future.
