Post-1935 changes in forest vegetation of Grand Canyon National Park, Arizona, USA: Part 1 - ponderosa pine forest
The author resampled vegetation study plots originally sampled in Grand Canyon National Park in 1935 to document changes in forest structure and composition.
The author found that eighty percent of the resampled mesic ponderosa pine plots had evidence of surface fire in Grand Canyon National Park; however, they did not find that surface fire related to changes in forest structure and composition from 1935–2004 except for the increase in the smallest diameter classes of white fire in which larger size classes were likely reduced by surface fire.

How do fire behavior, type, and intensity relate to species composition, non-natives, and structure?
