Impact of timber production and transport costs on stand management by
Chris B LeDoux(
)
4 editions published in 1988 in English and held by 410 WorldCat member libraries worldwide
S2Decisions to manage immature eastern hardwood stands on steep terrain must be based on an understanding of the impact of timber production costs on optimal rotation length and present net worth. Planners and managers can make improved decisions by knowing how the interaction of timber production and transportation costs affect individual stand management. Simulations with a complete systems model indicate that managers and planners must consider cable logging technology, transportation network standards, and transport vehicles.S3

Comparison of glue-line quality between gang edging and straight-line ripping by
Charles J Gatchell(
)
4 editions published in 1986 in English and held by 405 WorldCat member libraries worldwide
S2Gang edging with a dip-chain fed gang ripsaw produces gluing surfaces equal to those from a straight-line ripsaw in yellow-poplar (Liriodendron tulipifera) and red oak (Quercus rubra). Special care in gluing red oak was needed to get shear strengths equal to solid wood values. However, the strength comparisons between sawing methods showed no differences between gang edging and straight-line ripping regardless of gluing procedures.S3

Merchantable sawlog and bole-length equations for the Northeastern United States by
Daniel A Yaussy(
)
3 editions published in 1991 in English and held by 402 WorldCat member libraries worldwide
S2Describes development of merchantable-height equations in terms of sawlog and bole length for important tree species of the Northeastern United States. A modified Richards growth model is used to develop species-specific coefficients for 25 common species or species groups. Variability in merchantable sawlogs or bole length is accounted for by species, d.b.h., and site index. Predicted merchantable height when used in conjunction with published cubic-foot-volume or board-foot-volume equations provide realistic estimates of stand volume for average stand conditions in the Northeastern United States. Regression coefficients for merchantable bole length and sawlogs have been incorporated into NE-TWIGS.S3

Applying a crop-tree release in small-sawtimber white oak stands by
Jeffrey W Stringer(
)
4 editions published in 1988 in English and held by 402 WorldCat member libraries worldwide
S2Small-sawtimber white oak crop trees in Kentucky were released by a crown-touching technique. In two cutting treatments, 20 and 34 crop trees were released per acre at a total cost of $35 and $42, respectively. Both treatments yielded commercial volumes of cut material. Total mean merchantable volume (>5.0 inches d.b.h.) in cut trees was 693 cubic feet/acre, with approximately 2,400 board feet/acre in sawtimber (2 11.0 inches d.b.h.). On the basis of early crop-tree stem response, the released trees are growing 0.16 inch/year compared with 0.13 inch/year for the unreleased trees.S3

Pallet use in grocery distribution affects forest resource consumption location : a spatial model of grocery pallet use by
R. Bruce Anderson(
)
3 editions published in 1991 in English and held by 401 WorldCat member libraries worldwide
S2To assess the impact of grocery pallet production on future hardwood resources, better information is needed on the current use of reusable pallets by the grocery and related products industry. A spatial model of pallet use in the grocery distribution system that identifies the locational aspects of grocery pallet production and distribution, determines how these aspects influence the demand and supply of grocery pallets, and assesses the overall impact of grocery pallet consumption on the forest resource is described. Also presented is a method for estimating the overall quantity of new grocery pallet consumption by grocery distribution centers. This method is useful in assessing the effect of changes in grocery pallet consumption on the hardwood resource in a particular region.S3

Age and stem origin of Appalachian hardwood reproduction following a clearcut and herbicide treatment by
George R Trimble(
)
4 editions published in 1986 in English and held by 398 WorldCat member libraries worldwide
S2Seven years after a clearcut and herbicide treatment in a West Virginia stand of Appalachian hardwoods, root and stem ages were determined for sugar maple, black cherry, and white ash. Age was used to verify origin and origin was used to evaluate reproduction stem development 7 years after clearcutting. Sugar maple stems originated from advanced reproduction; black cherry originated primarily from seedlings that germinated during or after treatment; and white ash stems were a mixture of seedlings, advanced reproduction, and stump sprouts.S3

The determinants of hardwood lumber price by
William G Luppold(
)
4 editions published in 1985 in English and held by 397 WorldCat member libraries worldwide
S2Increased export activity in the hardwood and oak lumber markets coincided with rising prices of these commodities, which also coincided with an increase in the overall price level of all commodities. To determine the effect that exports have on the prices of hardwood and oak lumber, relative price models for these commodities were developed. Relative, rather than actual or nominal, price models were used to remove the effects of inflation. The models indicated that exports to Europe have had and will have an influence on hardwood lumber prices. Oak price seems to be more sensitive to changes in exports than overall hardwood lumber price. However, the main determinants of hardwood lumber and oak lumber prices were found to be domestic demand and millstock levels.S3

Hardwood trade trends : U.S. exports by
William G Luppold(
)
4 editions published in 1988 in English and held by 393 WorldCat member libraries worldwide
S2Between 1970 and 1986, hardwood log exports increased by 102 percent, hardwood lumber exports by 329 percent, hardwood veneer exports by 442 percent, and hardwood plywood exports by 61 1 percent. Much of this increase has been for white and red oak products in the European and Asian markets. The factors influencing these increases include increased cost of tropical and European hardwood products, rapid growth in European and Asian economies, and an emerging furniture industry in Taiwan. Given the ample supplies of temperate hardwood timber in the United States relative to the rest of the world, continued demand for U.S. hardwood products seems likely. However, the increase in this demand will be contingent on the value of the dollar against European and Asian currencies, growth in foreign economies, furniture production technology, and foreign consumer acceptance of substitute materials.S3

Revegetation after strip cutting and block clearcutting in northern hardwoods : a 10-year history by
C. Wayne Martin(
)
4 editions published in 1989 in English and held by 388 WorldCat member libraries worldwide
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

Low-cost opportunity for small-scale manufacture of hardwood blanks by
Bruce G Hansen(
)
4 editions published in 1985 in English and held by 388 WorldCat member libraries worldwide
S2We analyzed the manufacture of standard-size hardwood blanks from lumber on a relatively small scale by conventional processing. Requiring an investment of just over $200,000, the conventional mill can process 500 M bf (thousand board feet) of kiln-dried lumber annually. The study focused on the economics associated with manufacture of blanks from four speciesnorthern red oak, black cherry, hard maple, and yellow-poplar. Assuming a tax rate of 46 percent, returns ranged from 31 percent for hard maple to 38 percent for yellow-poplar. Plots were developed relating raw material input cost to blank prices necessary to achieve specified levels of return. The blanks investment seems suited to someone wishing to enter the wood business on a small scale, to sawmill operators wishing to upgrade and expand their product offering, and to small furniture and cabinet manufacturers wanting more control of their raw material situation.S3

Fuel supply structure of wood-fired power plants in the Northeast : loggers' perspective by
Neil K Huyler(
)
4 editions published in 1989 in English and held by 387 WorldCat member libraries worldwide
S2This study gauges loggers' perceptions of the impact of large biomass demand centers (electrical power generation) on the forest resource base in the Northeast. The loggers who supply these demand centers are business people with large capital investments in highly mechanized harvesting systems. Most of the loggers surveyed strongly believed that the post-harvest stand has improved as a result of fuelwood chipping; however, the impact of chip harvesting on the forest resource base was not clear.S3

Stand basal-area and tree-diameter growth in red spruce-fir forests in Maine, 1960-80 by
Stanley J Zarnoch(
)
5 editions published in 1990 in English and held by 384 WorldCat member libraries worldwide
S2Stand basal area change and individual surviving red spruce d.b.h. growth from 1960 to 1980 were analyzed for red spruce-fir stands in Maine. Regression modeling was used to relate these measures of growth to stand and tree conditions and to compare growth throughout the period. Results indicate a decline in growth. The regression models helped identify trends and relationships but were not useful for predicting growth due to the tremendous amount of variability in the growth of red spruce-fir stands.S3
