Compiled plot-level characterization data included stand age, disturbance history, tree density, tree biophysical measurements for calculation of the aboveground (ag) and belowground (bg) biomass/carbon pools, pre-fire and residual post-fire soil organic layer (SOL) depths, and estimates of combustion of tree structural classes. Also included were the measured slope and aspect for each site and an assigned moisture class based on topography. Data from 1,019 burned and 152 unburned sites are included. From the estimates of combusted ag and bg carbon pools and SOL losses, the total carbon combusted, proportion of pre-fire carbon combusted, and proportion of total carbon combusted was calculated for each plot. FWI system components were obtained for each plot from existing data sources based on the plot location, year of burn, and a dynamic start-up date (day of burn, DOB) from the global fire weather database including moisture and drought codes and indices of fire danger.

The outwash soils have low fertility, poor nutrient retention and are restricted from whole-tree harvesting (WTH) in some states, whereas the glacial till has medium nutrient retention and fertility, and is unrestricted from WTH. To assess the long-term sustainability of harvesting, a nutrient budget was constructed from field measurements, the National Cooperative Soil Survey (NCSS) database, and literature values for stem-only harvesting (SOH) and WTH at a 45-year rotation length and 11 rotations were simulated. The budgets showed that SOH and WTH recovery years, or the time necessary for the inputs to match outputs through leaching and one harvest, exceeded common rotation lengths for both soil types under all weathering scenarios, and the average WTH reduced the total available rotations by one harvest. The large variation in soil nutrient pools and harve...
