- ... Dry western forests (e.g., ponderosa pine and mixed conifer) were thought to have been historically old and park‐like, maintained by low‐severity fires, and to have become denser and more prone to high‐severity fire. In the Pacific Northwest, early aerial photos (primarily in Washington), showed that dry forests instead had variable‐severity fires and forest structure, but more detail is needed. H ...

- ... Biome transition zones where species co-exist near their geographic limits are expected to be among the most responsive to changes in climate that result in mortality of foundation species. Long-term (.13 years) patterns in dominance and cover of functional types were examined following the annual experimental removal of one of three foundation species at an arid-semiarid biome transition zone.
