In order to quantify and describe current harvest in northern hardwood forests, a large-scale field assessment was conducted in Michigan in 2010. We anticipated that many harvests would be in line with widely accepted published management guidelines. Specifically, we expected many harvests to follow Arbogast’s 1957 marking guidelines. We further hypothesized that variation would be present among landowner-types, presumably due to varied management objectives. 96 stands recently harvested stands under three different ownership types were sampled. Post-harvest measurements and pre-harvest estimates for each stand were compared to published guidelines. To compare stands to multiple guidelines at once, a system of harvest taxonomy was developed and applied. This original approach facilitated objective comparison of harvesting practices to literature-based metrics. In general, the results of comparisons to individual guidelines and the taxonomical classifications were congruent. Notable results were a lack of difference among the management practices of state, corporate, and NIPF owners. Approximately equal proportions of stands were cut following guidelines, more heavily, and more lightly than recommended.
