Forest Carbon Stocks and Fluxes After Disturbance, Southeastern USA, 1990-2010

Overview

Description

This dataset provides estimates of forest carbon stocks and fluxes in the form of aboveground woody biomass (AGB) and net ecosystem productivity (NEP), as a function of the number of years since the most recent disturbance (i.e., stand age) for forests in the southeastern USA at a 30 m resolution for the benchmark years 1990, 2000, and 2010. The study area includes: Virginia, North Carolina, South Carolina, Georgia, and Florida. Estimates were derived from an inventory-constrained version of the Carnegie-Ames-Stanford Approach (CASA) carbon cycle process model that accounts for disturbance processes as a function of years since disturbance for each combination of forest type, site productivity, and pre-disturbance biomass. Also provided are the core CASA model data inputs including: the year of the most recent disturbance according to the North American Forest Dynamics (NAFD), the Aerial Detection Survey (ADS), and the Monitoring Trends in Burn Severity (MTBS) data products; the type of disturbance; biomass estimates from the year 2000 according to the National Biomass and Carbon Dataset (NBCD); forest type group; a site productivity classification; and the number of years since stand-replacing disturbance, which is akin to forest stand age.
