Mp754: A Literature Review Of The Effects Of Intensive Forestry On Forest Structure And Plant Community Composition At The Stand And Landscape Levels, Erika L. Rowland, Alan S. White, William H. Livingston

Miscellaneous Publications

The effects of intensive forest management on forest structure and plant community composition are not well documented, particularly with respect to the forests in the Northeast. This review presents a six-part synthesis of the literature. The first section considers the effects of intensive forestry practices within the context of naturally regenerated stands. The second section reviews the changes associated with the planting of conifers in softwood sites, as well as those previously occupied by hardwood and mixed-wood stands. The third examines the impacts of intensive management specifically on bryophytes and lichens. The fourth section discusses changes in dead organic matter …

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 …

Forest Stand Dynamics, Update Edition, Chadwick Dearing Oliver, Bruce A. Larson

Yale School of the Environment Other Publications

This book describes the various growth patterns of forests from a mechanistic point of view. Its purpose is to help silviculturists, forest managers, and ecologists understand and anticipate how forests grow and respond to intentional manipulations and natural disturbances. Demands on the forest have been increasing for timber production, wildlife habitat, water protection, recreation, and protection from fires, insects, and diseases. These demands have created an emphasis on prescribing site-specific treatments for individual stands of trees, rather than treating broad areas uniformly

Mp716: New Forestry In Eastern Spruce-Fir Forests: Principles And Applications To Maine, Robert S. Seymour, Malcolm L. Hunter Jr.

Miscellaneous Publications

Eastern North America's spruce-fir forests have a unique ecological and human history which is reflected in their current vegetation, ownership patterns, and forest management practices. Furthermore, there are important differences within the region between the true boreal forest and the sub-boreal Acadian forest; this paper emphasizes the Acadian forest. Applying New Forestry to this region will require a modified approach which we outline by describing three basic principles. First, to provide the landscape context for New Forestry, we propose a triad of forest land allocation in which reserves and plantations would co-exist, surrounded by and embedded within a landscape managed …

B758: A Biomass Study Of The Thinning Potential And Productivity Of Immature Forest Stands In Maine, Harold E. Young, John H. Ribe, Donald C. Hoppe

Bulletins

The purpose of this study is to establish the degree of reliability that can be placed in biomass as a means of assessing thinning potential and site productivity of immature forest stands in Maine. The above ground biomass on 205 plots representing a variety of age classes in immature hardwood and softwood stands on meso, wet, and dry sites was cut and weighed including the standing dead trees on softwood sites. In addition, 45 point sample biomass plots were located and measured in mature all aged stands. Graphical analysis was used to relate stand characteristics to age by site and …

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.
