Total and merchantable tree height estimation equations were developed for Lake States species. Equations were developed from site index tree and merchantable tree height data from the USDA Forest Service Forest Survey project plots across Minnesota, Wisconsin and Michigan. The equations are intended for usage in forest survey inventory compilations for tree product yield and for projections with the STEMS growth projection model developed by the North Central Forest Experiment Station. Basic data sets plus model forms and model fitting considerations are described. Model coefficients for 25 Lake States species are given along with fit statistics and suggested implementation procedure.
