Treesearch

Existing regional growth-and-yield information for most of the northern forest types is summarized by species. Present research is concentrated on growth-simulation models, constructed by either aggregating available information or through individual tree growth studies. A uniformity of more refined measurements is needed so that future growth models can be tried for other species and forest types.

A report on the symposium held in July 1976 at the University of Maine, Orono, containing 35 papers presented at the meeting.

The non-Federal forest lands, which comprise three-fourths of the Nation's forest lands, are the key to meeting projected future needs for all forest products and uses. At the same time, the Federal role in State and Private forestry cooperative programs is being critically questioned. Public attitudes toward Federal expenditures, and the possibility of sunset legislation, may change the nature of Forest Service cooperative programs. One possible approach would be for each State to develop a comprehensive forestry plan suited to both State and national needs, perhaps related to a national...

The organizers of this symposium assigned me the task of the devil's advocate. My job is to convince you that we either do not need to increase wood yield or cannot it. Clearly they did not have much faith in my oratorical abilities because they have scheduled no less than 32 speakers to follow me, each dealing with a specific aspect of how to get on with intensive management. It is unlikely indeed that I would succeed in having the symposium cancelled as unnecessary and my title is admittedly facetious. However, I do have a deadly serious point to make. Simply stated my point is that as a...

The applicability of even-aged silviculture in the management of forest stands in the Northeast is examined through consideration of the forest stand, stand development, intermediate cuttings, and regeneration methods. It is concluded that even-aged silviculture is quite applicable in the management of forest stands in the Northeast.

For the proper application and practice of uneven-age management, one must consider residual stocking, maximum tree-size objective, and diameter distribution. All three components are described, and it is shown how they fit into a practical package for application in a timber tract.

Uneven-aged Management, to me, indicates some form of partial cutting, perhaps selective cutting or diameter limit control in the harvesting cut, which, in most cases, removes the larger diameter, more mature trees and leaves a residual stand composed of healthy, fast-growing, well-spaced second growth timber, with a good number of trees in the 6"-12" diameter class.

Established concepts of successful natural regeneration are not necessarily practiced on small ownerships of ten to 500 acres. Unevenage management will be the primary management system on small ownerships and natural regeneration is the most practical method of providing for continuous forest production. We can obtain satisfactory natural regeneration by good planning and proper supervision of the on site application of necessary techniques.

Intensive timber management can and is practiced on National Forest lands in the Northeast. There are, however many constraints and limitations which are placed upon the public lands manager. The key issue here is that the National Forests are PUBLIC lands which must be managed for the public.
