Middle and high elevation coniferous forest communities of the North Rim region of Grand Canyon National Park, Arizona, USA

M. A. White, John L. Vankat


Summary - what did the authors do and why?

The authors examined the structure and composition of forest stands along environmental gradients in Grand Canyon National Park to classify forest communities and determine what potential changes to structure and composition occurred in these stands following Euro-American settlement.

Publication findings:

The authors found that fire suppression policies in the early 20th century have resulted in increasingly homogenous species composition in mixed-conifer forests with greater horizontal and vertical fuel continuity. These changes make these stands more susceptible to high-severity fires.
