The Navajo Nation Department of Forestry (NDF) manages 596,728 acres of commercial forests and 4,818,815 acres of woodlands located along the Defiance Plateau and Chuska Mountains in northeastern Arizona. In previous years, the NDF managed the forest under an uneven-age forest plan, but today the NDF combines even- and uneven-age silvicultural treatments. Since 1991, there have been no commercial harvests and the amount of timber removed has been reduced from 15.9 million board feet to 4 million board feet. Concurrently, wildfires across the west have been increasing in frequency, severity and size over the last several decades. My research asks how changes in forest management have modified the composition of the forest as well as fire severity and occurrence. To answer this question, I am evaluating data from multiple sources including primary literature, forest inventory, maps and data sets from Monitoring Trends in Burn Severity project and the Navajo Forestry Department. I am comparing the growth/density of the forest over the past twenty years to that during previous management regime, and analyzing the potential impact on species composition, regeneration, mortality and the frequency and severity of fire (adding fuelwood, medicinal plants, food, wildlife, etc). I anticipate the reduced timber harvesting has resulted in increased tree density in the forest stand, changing the forest type from Ponderosa pine to mixed conifer forest and resulting in increased fuels and fire hazard. This project will deepen our understanding of the impacts of forest management decisions in this region, thus aiding the Navajo Nation and setting the groundwork for developing better strategies to sustain its natural resources and livelihood.
