Growth of Adjacent Red and Jack Pine Plantations in the Lake States
Abstract:In 25 pairs of adjacent plantations, mean annual increment of red pine (Pinus resinosa Ait.) was greater than that of jack pine (P. banksiana Lamb.) for 24 comparisons on a volume basis and for 20 on a weight basis. In no case did jack pine significantly outproduce red pine. Red pine mean annual increment averaged 29 cubic feet per acre greater than that of jack pine irrespective of site index, and this species differential is expected to increase as the stands grow older. The plantations averaged 36 years of age and represented a wide range of site indexes and soils throughout the northern Lake States.
