Book Description
Excerpt from The Variability of Paper Birch Seed Production, Dispersal, and Germination There appears to be no relationship between time of dispersal and size of seed crop; and in both the Maine and New Hampshire stands the bulk of the seed was dispersed every year before the ground was snow-covered. There is an advantage in this: seed dispersed on prepared seedbeds before snow falls will be held in place; seed falling on snow-covered seedbeds might be blown off.
