Download or read book Improvement in Butt log Grade with Increase in Tree Size for Six Hardwood Species written by George R. Trimble (Jr.) and published by . This book was released on 1965 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Work carried out by the Northeastern Forest Experiment Station in West Virginia in the past 12 years provides useful information about the relationships between tree d.b.h. and butt-log grade. The upper logs are not included in the relationships. Being smaller and containing more knots, these upper logs are generally of lower grade than the butt logs. Thus the average grade of all material in the sawlog portion of the tree is generally lower than the average grade of the butt log. In the West Virginia data, species differences in d.b.h.-grade relationship are readily apparent. This inherent tendency for species to have different proportions of the various grades in logs of the same size is a familiar phenomenon to grade-conscious foresters who work with hardwoods. The results in this paper provide a quantitative evaluation of this tendency for six of the local species.S3.

Download or read book Natural Disturbances and Historic Range of Variation written by Cathryn H. Greenberg and published by Springer. This book was released on 2015-10-26 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.

Download or read book Oak Forest Ecosystems written by William J. McShea and published by JHU Press. This book was released on 2003-06-04 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oak Forest Ecosystems focuses on the relationship between an oak forest's acorn yield and species of wildlife that depend on it. It begins by treating factors such as oak distribution, forest fires, tree diseases and pests, dynamics of acorn production, and acorn dispersal by birds and mammals. Special consideration is given to the phenomenon of masting—whereby oaks in a given area will produce huge crops of acorns at irregular intervals—a key component for wildlife researchers and managers in understanding patterns of scarcity and abundance in the creatures that feed on this crop. Relationships between oaks and animals such as mice, squirrels, turkeys, deer, and bear are discussed, as are the differences between eastern, southern Appalachian, southwestern, and California oak forests.
