Tb186: Assessing Silviculture Research Priorities For Maine Using Wood Supply Analysis, Robert G. Wagner, Ernest H. Bowling, Robert S. Seymour
Technical Bulletins
To identify the highest priorities for silviculture research in Maine, the authors of this report quantified the absolute and relative influence of future silvicultural investments (tree planting, herbicide application, and PCT) and commercial thinning on projected harvest levels and future wood supplies in Maine. They also quantified the absolute and relative importance of the growth and yield assumptions (via sensitivity analysis) used in estimating the influence of these silvicultural treatments on projected harvest levels and future wood supplies in Maine; and based on the absolute and relative importance of the growth and yield assumptions and on the influence of differing …
Tb149: Wood Property-Age Relationships Of Natural And Plantation-Grown Red Pine, Robert K. Shepard, James E. Shottafer
Tb149: Wood Property-Age Relationships Of Natural And Plantation-Grown Red Pine, Robert K. Shepard, James E. Shottafer
Technical Bulletins
This study examined changes in specific gravity, modulus of rupture, and modulus of elasticity with age for a natural stand and two plantations. It also examined differences in wood properties between the three stands and the effects of important variables on, and their interactions with, wood properties. Wood property data were obtained from microbending specimens selected at breast height from five trees in each stand.
Tb131: Tree Improvement In The Northeast: Interim Summary And Recommendations For Selected Species, K. K. Carter, D. H. Dehayes, M. E. Demeritt Jr., R. T. Eckert
Tb131: Tree Improvement In The Northeast: Interim Summary And Recommendations For Selected Species, K. K. Carter, D. H. Dehayes, M. E. Demeritt Jr., R. T. Eckert
Technical Bulletins
This publication of the regional research project NE-27, Genetics and Improvement of Northeastern Trees, is intended to provide an overview of current knowledge regarding genetic variation and tree improvement practices for eleven common tree species in the Northeast. The authors have attempted to summarize the information that will be most useful to forest managers, administrators, and field foresters in this region. Our intent is to be informative, not exhaustive.
Tb25: The Effect Of Stand Factors On The Productivity Of Wheeled Skidders In Eastern Maine, Ernest B. Harvey Iii, Thomas J. Corcoran
Tb25: The Effect Of Stand Factors On The Productivity Of Wheeled Skidders In Eastern Maine, Ernest B. Harvey Iii, Thomas J. Corcoran
Technical Bulletins
The objective of this study was to determine what forest stand factors, as they constitute a set of operating conditions, affect skidder and skidder crew productivity and the degree of their effect.
Tb15: The Standardization Of Symbols In Forest Mensuration, International Union Of Forestry Research Organizations
Tb15: The Standardization Of Symbols In Forest Mensuration, International Union Of Forestry Research Organizations
Technical Bulletins
This technical bulletin reprints the recommendations on the standardization of symbols in forest mensuration, originally published in 1959. The recommendations were made by a small working group in Section 25 of the International Union of Forestry Research Organizations, which was appointed at the Congress of the Union held in Rome in 1953. Members of the group were asked to enquire into the possibility of standarizing the use of symbols (and the systems of measurement) in forest mensuration and to make recommendations.
