Fire history and stand structure of two ponderosa pine-mixed conifer sites: San Francisco Peaks, Arizona, USA

Thomas A. Heinlein, Margaret M. Moore, Peter Z. Fulé, W. Wallace Covington


Summary - what did the authors do and why?

The authors reconstructed the contemporary and historical fire regime of a ponderosa pine forest and a mixed-conifer forest to determine how fire exclusion may have affected the forests’ structure and composition on the San Francisco Peaks in Northern Arizona.


Publication findings:

The author found that historically, the San Francisco Peaks of northern Arizona were dominated by ponderosa pine with an understory of scattered individuals of Douglas-fir, limber pine, and white fire. Currently, however, the species composition has shifted due to fire suppression to dense stands of less fire-tolerant Douglas-fir and white fir.
