The U.S. Forest Service National Forest System (NFS) manages approximately one fifth of the country’s forestlands. NFS has been directed to more closely monitor the influence of forest management on forest carbon sequestration so that greenhouse gas mitigation may be incorporated into the forest planning process. While significant advances have occurred in the field of terrestrial carbon cycle modeling, many current approaches are insufficient for NFS’s needs because they: 1) may not extend beyond the ecosystem to capture cross-sector dynamics such as management-related fossil fuel emissions and storage of carbon in forest products; 2) may not support assessment at the sub-regional and local scales where most forest planning occurs; and 3) may not offer robust tracking of uncertainty. A system addressing these needs, called the Forest Carbon Management Framework (ForCaMF), has been developed through a partnership between the Forest Service and NASA, and has been piloted in a county in Montana. Landsat imagery is critical to how ForCaMF visualizes the distribution of both forest carbon stocks and stock-resetting disturbances (e.g., harvests and fires) across individual planning units. Landsat-based change maps also contribute to the measurement of management-related emissions by quantifying forest road construction activity and pinpointing how far harvested timber must be hauled to move it from the forest to the mill. ForCaMF integrates monitoring of both ecological and non-ecological forest carbon dynamics under a probabilistic estimation framework, allowing annual assessment of carbon stocks and fluxes as they respond to particular harvest strategies and natural disturbance trends. This proposal details a plan to install ForCaMF across 10 million hectares in the Northern Rockies as a template for broader integration into the NFS planning process. ForCaMF has the capacity to substitute user-generated hypothetical disturbance scenarios for remotely sensed histories of harvest and natural events. The resulting ability to compare the carbon effects of alternative scenarios is critical for establishing the net carbon benefit of one management approach over another. NFS recognizes ForCaMF’s potential to transparently document likely carbon outcomes and uncertainties related to particular management strategies, and the Forest Service would pay more than 50% of the costs associated with this project. The proposed activities will not only likely lead to fundamental new insight into the relationship between forest management and forest ecology, but they will also improve the ability of the nation’s largest forest manager to incorporate greenhouse gas mitigation into forest management planning.
