Progress Report on a Set of Spruce Thinning Plots Established in 1906 in Corbin Park, N. H.
Plots established in an old-field spruce stand in 1906 by the Forest Service, thinned in 1906, 1915, and 1935, and remeasured at periodic intervals, has yielded data of particular interest to owners of stands of this character. Analysis of the data indicates that thinning of old-field spruce stands is beneficial in several respects; by increasing the net annual increment; by providing for a cash income to the owner above the cost of thinning; by decreasing mortality; and by providing conditions conducive to the establishment of abnndant coniferous reproduction.
