Apply group and individual selection cuts to maintain an uneven-aged system to promote three or more age classes and release crop trees. The creation of varying gap sizes allows for regeneration of shade tolerant and intolerant species and further promotes multiple age classes. With harvests occurring on cycles between ten and twenty years, one third of the stand basal area should be removed with each cutting cycle.
Individual trees selected for harvest are marked based on risk, defect, vigor, crown competition with dominant crop trees, or release of advanced regeneration. Areas selected for group harvest are chosen based on forest inventory data and were designed to leave 20 merchantable trees per acre. Best management practices are to be followed by retaining snags, slash, and residual trees. Leaving coarse woody debris and residual trees not only increases the structural diversity of the stand, it also provides wildlife habitat and protects water resources that could be affected by harvest operations.
Basal area should be primarily removed from red maple and sugar maple in order to decrease the abundance of these species in the stand. Black ash, paper birch, basswood, and northern red oak must also be reduced in basal area, but at a smaller magnitude than red maple and sugar maple.
The paper birch and red oak present are quality but represent a limited portion of the stand. In addition, advanced red oak regeneration is present. Therefore, group selection harvests should be used to maintain northern red oak and paper birch throughout the stand.
