Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1995 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviews the potential impacts of alternative silvicultural systems in Ontario boreal mixedwood forests on individual species and groups of wildlife. Begins with an overview of the ecology of boreal mixedwoods and a discussion of some of the concepts relevant to the later sections of the report, such as biodiversity. Alternative silvicultural systems are then reviewed, including modified clear-cut systems and the shelterwood system. The next four chapters cover habitat affiliations and the stand-level and large-scale effects of those silvicultural systems on the following categories of wildlife: birds, small mammals such as rabbits and squirrels, ungulates (moose, caribou), and furbearers with small, intermediate, and large home ranges.

Book excerpt: Summarises the potential use of alternative silvicultural (harvesting) systems on the productivity of boreal mixedwood forests. Begins with an overview of the ecology of boreal mixedwoods, including physical environment, stand dynamics, and landscape ecology; then provides detailed reviews of modified clear-cutting systems (including strip cutting, patch cutting, and seed-tree cutting), shelterwood systems, and selection systems (including group selection and individual tree selection). Also briefly discusses the environmental considerations that are associated with these systems (effects on soil, water resources, wildlife, and aesthetics). Concludes with a discussion of areas of uncertainty in the application of alternative systems and the perceived problems that have limited their use in boreal mixedwoods.

Marie, Ont.] : Great Lakes Forestry Centre. This book was released on 1997 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports on the short-term impacts of conventional (clear-cutting) and alternative (partial cutting) harvesting practices on the abundance and biodiversity of elements of forest soil fauna. Two groups of fauna were studied: ground-dwelling carabid beetles, and soil-dwelling springtails, mites, and Diptera larvae. The study area was in the Black Sturgeon Forest about 120 kilometres north-east of Thunder Bay, Ontario. Results presented include the effects of various harvesting treatments on species diversity and on individual species; effects of drought observed by comparing 1994 and 1995 samples; and impacts of logging trails on soil springtails and mites. Management implications for boreal mixedwood forests are discussed.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-scale clear-cut logging in the boreal forest may contribute to the loss of insect biodiversity through reductions in the amount of older, undisturbed forest and through stand-level decreases in structural heterogeneity. To investigate the long-term effects of clear-cutting on insect communities, hymenopteran and dipteran communities were surveyed with Malaise traps during the summer of 1998 in 12 mature (30-50 year old) post-logged and 12 unlogged boreal mixedwood stands in northeastern Ontario. Unlogged stands yielded a significantly higher abundance of Dolichopodidae (long-legged Ries), several Syrphidae (hoverflies) species, and the Syrphidae larval wood-inhabiting guild. These differences were predominantly due to the older ages of the unlogged stands which supported different habitat features, though some evidence of a logging effect per se was found. These results demonstrate the need for maintaining features characteristic of older forests in post-logged stands, and suggest a potential loss of insect species characteristic of older forests, particularly species dependent on downed woody debris, in the face of continued clear-cut logging activities.

This book was released on 1996 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents proceedings of a workshop held to summarise the current state of knowledge about the ecology of boreal mixedwood forests, to discuss management philosophies for these cover types, and to present information on new research relevant to the future management of boreal mixedwoods. Topics of individual presentations include boreal forests in Ontario, the role of forest disturbance, forest management, industrial use of boreal mixedwoods, forest data bases, forest vertebrate communities, habitat quality indicators, forest microclimate, organic and nutrient removals associated with harvesting, climate change impacts, prescribed fire, silvicultural operations, harvesting methods, vegetation control, ecosystem response to disturbance, site preparation, and effects of harvesting on forest fauna.
Download or read book Response to Disturbance in Boreal Mixedwood Ecosystems written by John B. Scarratt and published by . This book was released on 1996 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest management and harvesting strategies in the northern Ontario boreal mixedwood zone have traditionally focused on clear-cutting or selective harvesting followed by attempted conversion to conifers. Changing public expectations about forest management and demands for protection of non-timber values in the boreal zone have led to a need for integrated management of the boreal forest. This in turn has created the need to develop ecologically and operationally sound alternatives for managing those forests. Such a need is being addressed through the Black Sturgeon research project reviewed in this paper. The project focuses on long-term, stand-level ecosystem response to disturbance and silvicultural manipulation, and evaluates feasibility and impacts of adopting alternative forest management approaches that avoid clear-cutting. The emphasis is on understanding ecological processes and interrelationships. The research reviewed includes a fire ecology component, a site preparation component, and a harvesting component.

Book excerpt: Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

Download or read book Ecological Silviculture written by Brian J. Palik and published by Waveland Press. This book was released on 2020-05-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical silviculture has often emphasized timber models, fundamentally based in production agriculture. This books presents silvicultural methods based in natural forest models—models that emulate natural disturbances and development processes, sustain biological legacies, and allow time to take its course in shaping stands. These methods, dubbed “ecological forestry,” have been successfully implemented by foresters for decades managing a wide variety of forestlands. Ecological silvicultural strategies protect threatened and rare species, sustain biological diversity, and provide habitat for game and non-game species, all while providing timber in profitable ways.
