Abstract: Forest management to restore fire-adapted ponderosa pine ecosystems is a central priority of the Southwestern Region of the USDA Forest Service. Appropriately-scaled businesses are apt to play a key role in achieving this goal by harvesting, processing and selling wood products, thereby reducing treatment costs and providing economic opportunities. The manner in which treatments occur across northern Arizona, with its multiple jurisdictions and land management areas, is of vital concern to a diversity of stakeholder groups. To identify a level of forest thinning treatments and potential wood supply from restoration byproducts, a 20-member working group representing environmental non-governmental organizations (NGOs), private forest industries, local government, the Ecological Restoration Institute at Northern Arizona University (NAU), and state and federal land and resource management agencies was assembled. A series of seven workshops supported by Forest Ecosystem Restoration Analysis (ForestERA; NAU) staff were designed to consolidate geographic data and other spatial information and to synthesize potential treatment scenarios for a 2.4 million acre analysis area south of the Grand Canyon and across the Mogollon Plateau. A total of 94% of the analysis area is on National Forest lands. ForestERA developed up-to-date remote sensing-based forest structure data layers to inform the development of treatment scenarios, and to estimate wood volume in three tree diameter classes of <5”, 5-16”, and >16” diameter at breast height (dbh, 4.5’ above base). For the purposes of this report, the group selected a 16” dbh threshold due to its common use within the analysis landscape as a break point differentiating “small” and “large” diameter trees in the ponderosa pine forest type. The focus of this study was on small–diameter trees, although wood supply estimates include some trees > 16” dbh where their removal was required to meet desired post-treatment conditions.4 There was no concurrence within the group that trees over 16” dbh should be cut and removed from areas outside community protection management areas (CPMAs)...
