  • Abstract:

    Old-growth forest is uncommon across the northeastern United States, as most areas have been historically cleared for agriculture or harvested for timber. This study provides rare direct insight into the overstory and midstory dynamics across a semi-contiguous old-growth landscape in New England. Pisgah State Park in southwestern New Hampshire comprises 5300 ha of Hardwoods-Hemlock-White Pine forest, all but 300 ha of which was cutover by the 1880s. To protect a high-quality, old-growth stand from harvest, Harvard Forest purchased a 10 ha tract (the Harvard Tract) in 1927. In 1929 and 1930, Branch, Daley, and Lotti located and sampled all of the known remaining old-growth stands in the Pisgah area. This included 74 0.04 ha old-growth stands, 14 of which were located the Harvard Tract. They also surveyed 27 0.04 ha stands that had been cut just prior to the study (stump plots), where stumps as well as the remaining overstory trees were recorded. Note that only 61 old-growth plots and 23 stump plots have valid measurements. Species, diameter class, and position (overstory or midstory) were recorded for each tree; cover type, elevation, and location was described for each plot. Dead and downed trees were also recorded.

  • Methods:

    Stands were located within the Pisgah Forest in which no signs of human disturbance such as cutting or culling were evident. In each suitable stand, a sample plot of 0.1 acre was laid out with a staff compass and steel tape. The upper story, middle story, and advance growth were recorded.

    The upper story included all the dominant and codominant trees, which were tallied by species and by diameter and height classes. Diameter classes for the overstory were as follows: 0-10, 10-15, 15-20, 20-25, 25-30, 30-35, and 35 inches or greater. For this dataset, values that were recorded in classes are listed as the lower limit (i.e. if the tree fell in the 20-25 in class, it would be recorded as 20). The species forming this story were the basis for classification of the various stands into types.

    The middle story consisted of all of the intermediate and suppressed trees down to a height of 15 feet, which were also tallied by species, and diameter and height classes. The breaks for the midstory are: 0-4, 4-6, 6-10, 10-15, and 15 inches or greater. Trees in the upper and middle story are differentiated by the binary category “overstory,” which equals 1 if the tree is in the overstory and 0 if it is in the middle story.
