Specifications include, but are not limited to: Thin stands 1/3 +/- of the BA present where red pine is featured, with emphasis on retaining and releasing the healthiest, most vigorous trees present. Mark for operability and reduce damage to residual trees. Mark for removal red pine, hardwood [except oak], aspen and spruce/fir species by the following: 1. Provide a four-sided crown release to healthy white pine, hemlock, cedar and oak by marking the removal species listed above of any size. 2. Favor the retention of red pine trees > 13” DBH, and provide a four-sided crown release by marking the removal species mentioned above that are < 13” DBH. Do not allow this step to constrict the intent of thinning stand. It is good to have variable density, but ensure the logging can occur. 3. Areas containing aspen, spruce and balsam remove all to regenerate aspen this will increase species and structural diversity within the stand. 4. If basal area is still above desired, focus on the relative spacing and crown touching, and provide about 10-15 foot spacing ; Tree retention: • Red and white pine should be considered the featured tree species, so efforts to remove red & white pine trees with obvious disease issues must be a priority. • Mark other species as appropriate but preserve healthy examples of all species present. • Generally retain hemlock, cedar and oak; consider releasing them wherever it is convenient. • If cherry or paper birch are marked to cut, provide adequate space to encourage sprouting to maintain these species in the stands. • Where aspen is encountered, it may be left in place or cut and regenerated depending on condition and age. • Retention pockets ranging from ½ to 2 acres may be left undisturbed where age class diversity is evident and areas that feature a high percentage of reserved species. Also, retain patches of timber where the majority of the trees would yield one merchantable stick.
