This book was released on 1966 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Available in PDF, EPUB and Kindle. Book excerpt: S2Two even-age management systems, progressive strip cutting and block clearcutting, have been studied since 1970 on small watersheds at the Hubbard Brook Experimental Forest, New Hampshire. In the strip cutting, all merchantable trees were harvested in a series of three strips over 4 years (1970-74). In the block clearcutting, all trees were harvested in a single operation in 1970. This paper contrasts progressive strip cutting and block clearcutting for the 10-year period after initiation of harvest in terms of hydrologic response, erosion losses, stream water ions, nutrient leaching, nutrient removals in harvested products, and natural regeneration of vegetation.S3.
