Down deadwood (DDW) is a carbon component important in the function and structure of forest ecosystems, but estimating DDW is problematic because these data are not widely available in forest inventory databases. However, DDW data were collected on USDA Forest Service Forest Inventory and Analysis (FIA) plots during Maine's 1995 inventory. This study(More)
The forest floor is an important part of carbon storage, biodiversity, nutrient cycling, and fire fuel hazard. This paper reports on a study of litter and duff layers of the forest floor for eastern U.S. forests. The U. S. Department of Agriculture (USDA) Forest Service, Forest Inventory Analysis (FIA) program currently measures variables related to duff(More)
—Methodology is lacking to easily map Forest Inventory and Analysis (FIA) inventory statistics for all attribute variables without having to develop separate models and methods for each variable. We developed a mapping method that can directly transfer tabular data to a map on which pixels can be added any way desired to estimate carbon (or any other(More)
1. Estimate forest floor down woody material (DWM) mass for the western United States by extending modeling methodology being developed for the eastern United States from FIA data. The models link FIA's phase 3 (P3) DWM data to phase 2 (P2) plot data for greater inference. 2. Publish model results in a journal. There is an opportunity to extend work from a(More)
PROJECT OBJECTIVES: (1) Develop bulk density (specific gravity) auxiliary parameters for the eastern U.S. from Forest Inventory and Analysis (FIA) phase 3 (P3) soils data. (2) Use these parameters to estimate duff and litter fuel loading from P3 down woody material data to combine with phase 2 (P2) plot data to produce county-level duff and litter estimates(More)
