Cutfoot Experimental Forest 1934 cutting experiment in mature red and jack pine, plots 106 - 110

We provide historical silvicultural data from plots 106, 107, 108, 109, and 110 located on the Cutfoot Experimental Forest, which is in north-central Minnesota within the Chippewa National Forest (known as the Minnesota National Forest at the time of plot establishment). The data included in this publication document the results of different thinning treatments on mature red (Norway) and jack pine. Five plots were established in 1934 with different spacing and were reassessed in 1939, 1944, 1946, 1950, and 1953. Plots were differentiated by the type of harvest treatment. These included: group selection, light selection, heavy selection, and commercial, as well as a control plot. Data are provided in two comma-delimited ASCII text files which contain 1) diameter at breast height (DBH), crown class, and height measurements of mainly red (Norway) pine on five different plots (plots 106 - 110) between 1934 and 1953; and 2) sleet damage measurements from 1940.
The purpose of these data was to determine a satisfactory method of cutting mature red (Norway) pine so as to provide for a second cut and to secure satisifactory reproduction at the end of the rotation.
