Paper birch trees are generally considered prolific seeders that produce at least some seed every year and very large crops of seed periodically. Seed dispersal is widely assumed to begin in early fall and to continue through the winter months. Germinative capacity has been assumed to be fairly low.

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.
