Forest-level appendices to the assessment of the influence of disturbance, management activities, and environmental factors on carbon stocks of U.S. National Forests

This is a supplement for the General Technical Report RMRS-GTR-402 “Assessment of the influence of disturbance, management activities, and environmental factors on carbon stocks of U.S. National Forests" (Birdsey et al. 2019). Included are nine appendices that contain forest-level carbon information, model results, key figures, and interpretation for individual national forests across the nine National Forest System regions in the U.S. This supplement provides information on how carbon stocks in individual national forests have been affected by factors such as timber harvesting, natural disturbances, climate variability, increasing atmospheric carbon dioxide concentrations, and nitrogen deposition. The assessments reported here are based on a detailed disturbance, climate, and atmospheric history of each national forest, and two forest carbon models: the Forest Carbon Management Framework (ForCaMF) model and the Integrated Terrestrial Ecosystem Carbon (InTEC) model. Regional-scale summaries are provided in the main GTR.This information supports national forest units in assessing carbon stocks, quantifying carbon outcomes of broad forest management strategies and planning, and meeting carbon assessment requirements of the 2012 Planning Rule and Forest Service guidance. Results of these assessments provide context for project-level decisions, separated from the effects of factors that are beyond the control of land managers.
