Progress Report on a Set of Spruce Thinning Plots Established in 1906 in Corbin Park, N. H

Puntos clave

Thinning operations improved net annual increment, supporting healthier forest growth over the years.
The cash income generated from thinning exceeded the associated costs, benefiting landowners financially.
Decreasing mortality rates of trees were observed, contributing to the overall health of the spruce stands.
Conditions for establishing abundant coniferous reproduction were created through effective thinning practices.

Resumen

Abstract 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.
