Download or read book Quality Index Tables for Some Eastern Hardwood Species written by Joseph J. Mendel and published by . This book was released on 1970 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Ever since the quality-index (Q.I.) concept was introduced by A.M. Herrick in 1946, its importance as a measure of timber value has grown: and it has been used, not only in other research efforts, but also as a tool to be used by foresters and timber operators (Herrick 1946). We have recently employed the Q.I. concept in our rate-of-value-increase studies on nine tree species in the Northeast and recognized that, as a byproduct of this study, the log-quality indexes would be useful to timber operators. This paper briefly reviews the quality-index concept, presents log-quality index tables for a selected group of eastern hardwood tree species, and explains how timber operators can use Q.I. for evaluating the lumber that can be sawed from logs and trees. The Q.I. tables are based on two different lumber price reporting services and cover different geographic regions. Those species that occur in more than one region have a different Q.I. in each region. S3.

Download or read book Method for Applying Group Selection in Central Appalachian Hardwoods written by Gary W. Miller and published by . This book was released on 1995 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public concern over the adverse visual impact of clearcutting has heightened interest in developing and testing alternative regeneration practices for central Appalachian hardwoods. When applied properly, group selection, which entails making small openings within a timber stand at regular intervals, can meet aesthetic goals while providing suitable light conditions to reproduce shade-intolerant species. Volume control and residual stand density are used to regulate periodic cuts, which include volume removed to create openings plus volume removed between openings to improve the quality and distribution of the residual stand. In central Appalachian hardwoods, openings must have a minimum size of 0.4 acre; all stems 1.0 inch d.b.h. and larger are cut to reproduce desirable shade-intolerant species. Maximum opening size is based on aesthetic requirements or other management constraints. Where reproduction of shade-intolerant species is acceptable, openings can be as small as a space occupied by a few trees. Openings should be located using the worst first approach to give the growing space occupied by mature trees or risky trees to faster growing, desirable regeneration. The residual stand between openings should be improved by cutting poor quality or high-risk trees. The recommended residual basal area in sawtimber-size trees (11.0 inches d.b.h. and larger) is related to northern red oak site index (SI): 70 to 85 ft2/acre for SI 80.55 to 70 ft2/acre for SI 70, and 40 to 55 ft2/acre for SI 80. These field-tested methods can help forest managers initiate group selection in second-growth Appalachian hardwoods. Guidelines are presented for computing the cut, determining size, location, and number of openings, and marking the stand.

Download or read book Appalachian hardwood stump sprouts are potential sawlog crop trees written by Neil I. Lamson and published by . This book was released on 1976 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of 8- and 12-year-old hardwood stump sprouts was made in north-central West Virginia. Species surveyed were yellow-poplar, black cherry, red oak, red maple, and basswood. Of the stumps cut 12 years ago, 66 percent produced at least one dominant or codominant sprout that originated at groundline and was free from forks in the lower 25 feet of the bole. The abundance and quality of these stump sprouts indicated that many of them can be considered as potential sawlog crop trees.

Download or read book Estimating Northern Red Oak Site-index Class from Total Height and Diameter of Dominant and Codominant Trees in Central Appalachian Hardwood Stands written by Neil I. Lamson and published by . This book was released on 1987 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Northern red oak site-index (SI) class is estimated using height and diameter of dominant and codominant trees for five Appalachian hardwood species. Methods for predicting total height as a function of diameter are presented. Because the total height of 4- and 6-inch trees varies less than 5 feet for the three northern red oak SI classes, use trees that are at least 8 inches in d.b.h. when estimating site class.S3.

Available in PDF, EPUB and Kindle. Book excerpt: S2Tree quality is an important factor in determining the market value of hardwood timber stands, but many forest inventories do not include estimates of tree quality. Butt-log grade distributions were developed for northern red oak, black oak, white oak, chestnut oak, and yellow-poplar using USDA Forest Service log grades on more than 4,700 trees in West Virginia. Butt-log grade distributions indicate the probabilities associated with each grade for each species and d.b.h. class. These estimates are useful for predicting the value of timber stands for which stand tables are available.S3.
