Managing for Late-Successional/Old-Growth Characteristics in Northern Hardwood-Conifer Forests William S
Forest Ecology and Management 235 (2006) 129–142 www.elsevier.com/locate/foreco Managing for late-successional/old-growth characteristics in northern hardwood-conifer forests William S. Keeton * Rubenstein School of Environment and Natural Resources, University of Vermont, Burlington, VT 05405, United States Received 19 March 2006; received in revised form 2 August 2006; accepted 2 August 2006 Abstract In the northern hardwood region of North America managing for late-successional forest habitats and functions is an important element of ecosystem management. This study tests the hypothesis that uneven-aged practices can be modified to accelerate rates of late-successional forest development. An approach, termed ‘‘structural complexity enhancement’’ (SCE), is compared against conventional uneven-aged systems modified to increase post-harvest structural retention. Experimental treatments, including controls, were applied to 2 ha units and replicated at two multi- aged northern hardwood forests in Vermont, USA. Structural objectives include vertically differentiated canopies, elevated large snag and downed log densities, variable horizontal density (including small gaps), and re-allocation of basal area to larger diameter classes. The latter objective is achieved, in part, by cutting to a rotated sigmoid diameter distribution. This is generated from a basal area (34 m2 haÀ1) and tree size (90 cm dbh) indicative of old-growth structure. Forest structure data have been collected over 2 years pre-treatment and 3 years post-treatment. Fifty-year simulations of stand development were run in NE-TWIGS and FVS comparing treatment and no treatment scenarios. Simulations also tested the sensitivity of large tree development to prescription parameters. Leaf area index retention was spatially variable but significantly (P < 0.001) greater under SCE (91%) compared to conventional treatments (75%). -

Effects of Small Patch Cutting on Sugar Maple Regeneration in New Hampshire Northern Hardwoods
Field Note Effects of Small Patch Cutting on Sugar Maple Regeneration in New Hampshire Northern Hardwoods William B. Leak, USDA Forest Service, Northeastern Research Station, P. 0. Box 640, Durham, NH 03824. ABSTRACT: In many northern hardwood stands in New Hampshire and New England, partial cutting or single-tree selection result,s in understories with a high proportion of beech and other species with low timber values. Patch cutting, using small openings of about 1/4-ac in size or larger coupled with sufficient logging disturbance, has proved to be an effective way to replace understories of beech and other less valuable species with a new stand containing a high proportion of yellow and paper birch in mhture with other deciduous species. Unless present as well-developed advanced regeneration, sugar maple is seldom common in the new stands produced by small patch cutting. However, when these early successional stands reach 40-50 years of age, understories dominated by sugar maple and with lesser proportions of beech frequently develop, possibly due to the rich leajyall, lower proportions of beech litter, and/or changed light conditions. Although small patch cutting may not immediately regenerate abundant sugar maple, it appears as though this technique may help over time to maintain sugar maple as a signiJicant component of northern hardwood forests.

Development of the Selection System in Northern Hardwood Forests of the Lake States: an 80-Year Silviculture Research Legacy
Chapter 9 Development of the Selection System in Northern Hardwood Forests of the Lake States: An 80-Year Silviculture Research Legacy Christel Kern, Gus Erdmann, Laura Kenefic, Brian Palik and Terry Strong Abstract The northern hardwood research program at the Dukes Experimental Forest in Michigan and Argonne Experimental Forest in Wisconsin has been adapt- ing to changing management and social objectives for more than 80 years. In 1926, the first northern hardwood silviculture study was established in old-growth stands at the Dukes Experimental Forest. In response to social demands for more “natural” forestry, the study included then-contemporary practices (e.g., liquidation of old- growth forest) and new approaches (e.g., partial cuttings). By 1953, the partial cut- ting treatments were deemed most sustainable (Eyre and Zillgitt, Partial cuttings in northern hardwoods of the Lake States: twenty-year experimental results. Technical Bulletin LS-1076, 1953), and led to the creation of an uneven-aged stand structural guide that is still widely used today: the famed “Arbogast Guide” (Marking guides for northern hardwoods under the selection system. Station Paper 56, 1957). Charis- matic figures such as Raphael Zon, Windy Eyre, William Zillgitt, and Carl Arbogast Jr. were important to establishing this research and its early application in the Lake States region. Since then, research at the Dukes and Argonne Experimental Forests has expanded to evaluate a range of management alternatives for northern hard- wood forests, including approaches designed to sustain biodiversity, habitat, and timber production. In addition, the long-term studies provide new opportunities for larger-scale applications and research unforeseen at the studies’ establishment. -
Sampling and Measurement Protocols for Long-Term Silvicultural Studies on the Penobscot Experimental Forest
United States Department of Agriculture Sampling and Measurement Protocols for Long-term Silvicultural Studies on the Penobscot Experimental Forest Justin D. Waskiewicz Joshua J. Puhlick Laura S. Kenefic John C. Brissette Nicole S. Rogers Richard J. Dionne Forest Northern General Technical Service Research Station Report NRS-147 April 2015 Abstract The U.S. Forest Service, Northern Research Station has been conducting research on the silviculture of northern conifers on the Penobscot Experimental Forest (PEF) in Maine since 1950. Formal study plans provide guidance and specifications for the experimental treatments, but documentation is also needed to ensure consistency in data collection and sampling protocols. This guide details current sampling and measurement protocols for three of the longest running Forest Service experiments on the PEF: (1) the management intensity demonstration (1950 to present), (2) the compartment management study (1952 to present), and (3) the auxiliary selection cutting study (1953-present). Each of these long-term stand-scale experiments use plot-based measurements of trees taken at periodic intervals. Additional data collected vary and include regeneration, recruitment, and mortality; amount, size, and decay of dead wood; and stand structural characteristics such as heights, crown dimensions, and spatial locations of trees. Descriptions provided here are the basis for data collection in the relevant studies on the PEF, inform interpretation of the published databases, and serve as a model for silvicultural studies elsewhere.

FOREST MANAGEMENT 101 A handbook to forest management in the North Central Region This guide is also available online at: http://ncrs.fs.fed.us/fmg/nfgm A cooperative project of: North Central Research Station Northeastern Area State & Private Forestry Department of Forest Resources, University of Minnesota Silviculture 21 Silviculture Silviculture The key to effective forest management planning is determining a silvicultural system. A silvicultural system is the collection of treatments to be applied over the life of a stand. These systems are typically described by the method of harvest and regeneration employed. In general these systems are: Clearcutting - The entire stand is cut at one time and naturally or artificially regenerate. Clearcutting Seed-tree - Like clearcutting, but with some larger or mature trees left to provide seed for establishing a new stand. Seed trees may be removed at a later date. Seed-tree 22 Silviculture Shelterwood - Partial harvesting that allows new stems to grow up under an overstory of maturing trees. The shelterwood may be removed at a later date (e.g., 5 to 10 years). Shelterwood Selection - Individual or groups of trees are harvested to make space for natural regeneration. Single tree selection 23 Silviculture Group tree selection Clearcutting, seed-tree, and shelterwood systems produce forests of primarily one age class (assuming seed trees and shelterwood trees are eventually removed) and are commonly referred to as even-aged management. Selection systems produce forests of several to many age classes and are commonly referred to as uneven-aged management. However, in reality, the entire silvicultural system may be more complicated and involve a number of silvicultural treatments such as site preparation, weeding and cleaning, pre-commercial thinning, commercial thinning, pruning, etc. -
