Book Description
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
"Seed germination and seedling establishment of paper birch (Betula papyrifera Marsh.) and yellow birch (Betula alleghaniensis Britton) are most satisfactory where there is abundant soil moisture and freedom from excessively high soil temperature. In a cutover forest, these conditions occur most frequently in areas shaded from direct sunlight and on scarified seedbeds that contain exposed mineral soil (1.4). Attempts to encourage birch regeneration, then, could logically take two forms: use of cutting methods that provide the optimum degree of shade, and/or seedbed preparation. The study reported here deals with the first possibility.S3.
