Lack of Viable Seeds in the Forest Floor After Clearcutting
The viability of seeds of northern conifers apparently does not persist in the forest floor for more than one year. A set of forest-floor samples collected two years after a heavy seed crop and one year after a seed-crop failure did not produce any conifer germinants, regardless of whether or not the surfaces of the samples were disturbed. A second set of forest-floor samples collected the spring after a good conifer seed crop yielded many conifer germinants. Forest managers should not rely on seed in the forest floor for natural regeneration of northern conifers.
