Thinning the 1927 “Graveyard” red pine stands in the Cutfoot Experimental Forest

We provide historical silvicultural data from the “Graveyard” plots 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 thinning red pine. Four plots were established in 1927 with different spacing and were reassessed in 1932, 1937, 1944, 1949, and 1953. Plots included 6x6, 8x8, and 10x10 foot spacing as well as a control plot. Data are provided in three comma-delimited ASCII text files which contain 1) diameter at breast height (DBH), crown class, and height measurements of mainly red (Norway) pine on four different plots (plots 22-25) between 1927 and 1953; 2) DBH and height measurements of all 4 plots in 1973; and 3) abundance of vegetation within the plots in 1932.
The purpose of these data was to study the effects of various degrees of non-commercial thinning on the future growth and yield of red (Norway) pine stands.
