The magnificent stands of old-growth trees that characterize the forests of western North America depend on periodic fires for their creation or survival. Deprived of that essential disturbance process eventually they die, leaving an overcrowded grow
Shaped by fire for thousands of years, the forests of the western United States are as adapted to periodic fires as they are to the region's soils and climate. Our widespread practice of ignoring the vital role of fire is costly in both ecological an

Culturally modified trees (CMTs) are trees with scars that reflect human utilization of forested ecosystems. Some CMTs can reveal unique knowledge of native cultures and insight to peoples' subsistence and land use in the past, and are mostly to be f

Isolated wilderness ecosystems with a history of frequent, low-severity fires have been altered due to many decades of fire exclusion and, as a result, are difficult to restore for philosophical and logistical reasons. In this paper, we describe the

In the northern Rocky Mountains, whitebark pine (Pinus albicaulis) is rapidly declining as a result of previous fire exclusion policies, mountain pine beetle (Dendroctonus ponderosae) outbreaks, and white pine blister rust (Cronartium ribicola). Blis
