Download or read book Revegetation After Strip Cutting and Block Clearcutting in Northern Hardwoods written by C. Wayne Martin and published by . This book was released on 1989 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Revegetation was studied during the first 10 years after clearcutting two sites in the northern hardwood forest of New Hampshire. One site was a 12-ha block clearcut; the other was a 36-ha progressive strip cut harvested in three phases. Permanent plots on each site were measured at 140 4-year intervals. Changes in the density and biomass of trees, shrubs, and herbs are presented with emphasis on the major commercial species and their primary noncommercial competitors. S3.

Book excerpt: Like ecology, environmental science is multi- and interdisciplinary. The three major subdisciplines of environmental science are : Population, Resources, Environment. Of the above three major subdisciplines with environmental science, this book is more concerned with the third - the ecological effects of stressors, with particular reference to those associated with the activities of humans. A chapter deals with the use and abuse of biological resources and the emerging field of ecological economics. Some sections deal with environmental impact assessment; ecological monitoring; and the responsibilities of ecologists in environmental issues, environmental education, and the design of sustainable economic systems.

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.

Book excerpt: S2Three system 6 mill-size alternatives were designed and evaluated to determine their overall economic potential for producing standard-size hardwood blanks. The study focused on developing standard discounted cash flow measures. Internal rates of return ranged from about 15 to 35 percent after taxes. Secondary effort was directed at providing accounting cost summaries to facilitate cost comparison of standard-size blanks with rough-dimension stock. Cost per square foot of blanks ranged from about $0.88 to $1.19, depending on mill size and the amount of new investment required.S3.
