Mark record


Between September 1957 and August 1962 periodic red pine seed collections were made in a cut-over stand that originally supported a mixture of red and jack pine. A partially cut area and one-chain-wide clear-cut strips, from which all jack pine were cut, were sampled. During the five-year period, 5.5 and 11.2 pounds of seed per acre were dispersed on strip-cut and partial-cut areas, respectively. Maximum dispersal occurred during the autumn, except in 1959 when cool, rainy weather delayed seed dispersal. Seed quality varied directly with size of seed crop and with intensity of seed dispersal.
