Estimating forest floor fuels in eastern U.S. forests
Abstract
The Forest Inventory Analysis (FIA) program (U.S. Department of Agriculture, Forest Service) systematically samples the nation's forests and currently measures variable related to down woody material (DWM) on a subsample of its plots in the third phase of a 3-phase sampling design. This paper focuses on: (1) compiling estimates of DWM within limitations of existing FIA measurements; (2) modeling available data for spatial application of the DWM to FIA's large sample of phase-2 plots across the eastern U.S.; and (3) discussing potential improvements to FIA measurements that would enhance estimates of DWM across the region.
