Abstract

State and transition models are being utilized in forest management analysis processes to evaluate assumptions about disturbances and succession. These models assume valid information about seral class successional pathways and timing. The Forest Vegetation Simulator (FVS) was used to evaluate seral class succession assumptions for the Hiawatha National Forest in Michigan’s Upper Peninsula. Forest Inventory and Analysis (FIA) plots located on the Hiawatha were stratified by Ecological Land Type and major forest type. A set of algorithms was developed for FVS to grow and evaluate the size class of the plot at each time step of the simulation. Results were evaluated to determine the amount of time vegetation spends in each state before it succeeds. This information was used as basic input for both the Vegetation Dynamics Development Tool and the Spectrum forest planning model used by the Hiawatha for its 2006 forest plan revision.
