Book Synopsis The Impact of Historic Logging on Woody Debris Distribution and Stream Morphology in the Great Smoky Mountains National Park, North Carolina-Tennessee by :
Download or read book The Impact of Historic Logging on Woody Debris Distribution and Stream Morphology in the Great Smoky Mountains National Park, North Carolina-Tennessee written by and published by . This book was released on 2008 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1900s, large sections of the Great Smoky Mountains were in- tensively logged. Since then, most locations have been allowed to naturally become forest-covered again, resulting in areas of secondary growth and old growth forest. To determine whether dierences in large woody debris (LWD) loading and channel morphology persist today, I measured LWD, channel widths and depths, and channel bed sediments of streams in old and secondary growth forest in the Great Smoky Mountains National Park. LWD pieces in streams in old growth had larger mean diameters and lengths compared to LWD in streams in secondary growth forest. Streams in old growth had 5.6 times more LWD volume than those in secondary growth. More LWD pieces were in debris dams in old growth than in secondary growth forest. Channel bed sediment size did not dier signicantly between streams in old and secondary growth forest. Channel widths and depths were signicantly larger in streams in old growth forest. LWD pieces aected channel depth primarily by creating pools and causing deposition of sediment. LWD aected width by directing stream ow toward banks and by protecting banks from erosion. I observed that the orientation of LWD was important in determining its geomorphic role. Although I found no relationship between LWD loading and watershed area, I found a relationship between watershed area and the importance of LWD in impacting channel morphology. Despite dierences in LWD frequency and total volume, streams in old and secondary growth forest diered little in width and depth in the largest watersheds in this study. However, in smaller watersheds, streams in old growth were not as narrow or as shallow as streams in secondary growth. LWD loading can vary substantially between streams, even those with similar surrounding forest types, climate, and disturbance histories; therefore, caution should be exercised when using LWD loading rates from other studies in environmental management. Despite nearly 80 years of forest regrowth, LWD loading and channel morphologies of streams still show the impacts of logging.

Book Synopsis Ecological Bulletins, Ecology of Woody Debris in Boreal Forests by : Bengt Gunnar Jonsson
Download or read book Ecological Bulletins, Ecology of Woody Debris in Boreal Forests written by Bengt Gunnar Jonsson and published by Wiley-Blackwell. This book was released on 2001-12-21 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today dead trees are not only viewed upon as waste and as potential sources of pest species. Instead they have gained an increased attention as key factors for biodiversity in many ecosystems. This change in focus and concern has sparked intense research activities directed to explore the ecological role of dead trees in forest ecosystems. Focus is directed into three main areas: 1) to understand the patterns of woody debris availability in relation to forest stand dynamics and effects of forestry, 2) the role of woody debris in nutrient and particularly carbon dynamics in forest ecosystems, and 3) the pattern and biology of the utilization of woody debris for a large number of wood-dependent species. This volume summarises the present knowledge and presents a set of case studies on the role of dead wood in boreal forests. The focus is on Fennoscandian boreal forests. However, the results presented have a wide applicability and thus the volume may serve as a general introduction to the importance of woody debris in forest ecosystems.

This book was released on 2014 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest ecosystems are an important sink in the global carbon cycle. Coarse woody debris (CWD, tree remains greater than or equal to 20cm in diameter), which makes up 20% of the aboveground forest biomass, can be an important indicator of historical forest disturbance events and is an important variable for establishing carbon storage baselines. Eighty plots (0.04 ha) located in old-growth temperate deciduous forest within Lilley Cornett Woods Ecological Research Station (LCW), southeastern KY, USA, were used to assess spatial and temporal dynamics in CWD. These plots were sampled for CWD three times (1989, 1999, and 2012) using identical methods and all samples were identified to species, assigned to a decomposition class, and measured in length and width to estimate volume and sample biomass. We found an increasing trend in CWD biomass that was both evenly-distributed across species and exhibited a distinct spatial pattern. The increasing deposition and spatial relationship were explained by recent disturbance events, as well as environmental variables. Because less than 1% of northeastern forests are old growth and climate change alters forest carbon balance, this study satisfies a current need for ongoing documentation of old-growth forests.

Book excerpt: As our understanding of the importance of large woody debris (LWD) evolves, planning for its production in riparian forest management is becoming more widely recognized. This report details the development of a model (CWD, version 1.4) that predicts LWD inputs, including descriptions of the field sampling used to parameterize parts of the model, the theoretical and practical underpinnings of the model's structure, and a case study of CWD's application to a stream in Wyoming's Bridger-Teton National Forest.
Book Synopsis An Analysis of the Ecology and Public Perception of Coarse Woody Debris in Virginia by : Nicholas E. Fuhrman
Download or read book An Analysis of the Ecology and Public Perception of Coarse Woody Debris in Virginia written by Nicholas E. Fuhrman and published by . This book was released on 2004 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coarse woody debris (CWD) is an important habitat component for wildlife, fish, and plants and is important in nutrient cycling and soil formation. Knowledge of the volume, distribution, and use of CWD across Virginia would be useful to forest managers modeling nutrient budgets in southeastern forests and is important to wildlife management efforts. Knowledge of the effectiveness of informational brochures and cooperative learning activities/presentations at influencing public perception of CWD is important to program design and evaluation efforts in teaching and extension. The objectives of this study were to quantify the relationship between forest cover type and CWD volume, correlate CWD volume with small mammal and bird activity, distribute information on the advantages and disadvantages of CWD using informational brochures and cooperative learning activities/presentations, and compare the effectiveness of such teaching techniques at influencing public perception of CWD. The volume and wildlife use of CWD was assessed within 12 mature second-growth stands in Virginia. Volume of CWD was measured using fixed-area plots. Use of CWD by small mammals and birds was assessed by noting bodily, foraging, or movement evidence. Pre- and post-survey instruments were used to evaluate how perceptions were altered in first year college students who either reviewed an informational brochure or participated in a cooperative learning activity/presentation. Results suggested that the management of CWD for wildlife was most needed in southeastern Virginia where CWD volumes were lowest and that the value of CWD for wildlife was best conveyed through cooperative learning activities/presentations and may be important to landowner education efforts. Results suggested that management efforts to increase CWD volumes in Virginia should focus on coniferous dominated stands where CWD volumes were lowest. Such a finding, combined with the knowledge that the value of CWD was best conveyed through presentations, suggests that landowners of coniferous woodlots could be effectively educated with presentations. Given that brochures were more effective for females than males, brochures addressing natural resource issues might be the most appropriate, cost effective method of education at events that target female audiences. Knowledge gained from this study that CWD management for wildlife would be most appropriate in western Virginia where CWD was most used by wildlife for travel and that presentations were most effective at reaching suburban participants may be important to outreach program design efforts. Regardless of academic major, presentations were more effective at generating positive attitudes toward CWD. The results of this study suggest that the choice between informational brochures and presentations for influencing public perceptions of CWD will likely be influenced by the demographics of the target audience and the relevance of the topic locally.
