Available in PDF, EPUB and Kindle. Book excerpt: Coarse woddy debris (CWD) plays a crucial role in the ecological functioning of many terrestrial and aquatic ecosystems. A prominent feature of forests around the world, CWD represents a considerable storage of nutrients and energy in these systems. Forest management practices have tended to reduce quantitites of CWD in many forests. Despite the acknowledged importance of CWD, little is known about how it influences ecological processes in many ecosystems, or of how forest management affects its role in biogeochemical cycling, especially in forested wetlands. This project examined the effect of forest management and flood frequence on the biomass and decay rate of river red gum (Eucalyptus camaldulensis Dehn.) CWD in the Millewa State Forest on the River Murray floodplain in south-eastern Australia. To determine the effect of forest management on quantities of CWD, surveys of CWD biomass were carried out in old-growth (unmanaged) forest, and in managed, frequently flooded and infrequently flooded forests. The rate of decay of CWD in frequently flooded and infrequently flooded forests was measured by assessing weight loss from logs cut over the last 47 years. Total biomass of CWD in the old-growth, frequently flooded river red gum forest in this study was typical of old-growth forests studied in other countries, although the biomass of fallen CWD was relatively high. Total CWD biomass in the old-growth, frequently flooded forest was significantly greater than in managed, frequently flooded and managed, infrequently flooded forests, which were not significantly different. Wood decay rates (k) were 0.0041 y-1 for frequently flooded samples, and 0.0045 y-1 for infrequently flooded samples. These rates are very low by world standards. Turnover of CWD in old-growth forest was greater than in both managed frequently flooded and managed, infrequently flooded forests. In frequently flooded, managed forest, leaf litter had a greater turnover than CWD. Storage of nitrogen in CWD in both old-growth, frequently flooded and managed, frequently flooded forests was greater than storage in leaf litter. In river red gum forests, CWD may be more important as a storage of nutrients and energy than as a contributor to organic matter turnover. Forest management has substantially reduced quantities of CWD in the Millewa forests, but frequency of flooding has little influence on decay of red gum CWD during the first 47 years after logging.0.
Book Synopsis Coarse Woody Debris in Riparian Corridors of Central Pennsylvania by : Timothy Gould

Available in PDF, EPUB and Kindle. Book excerpt: The wetlands and riparian corridors of North Americas Mid-Atlantic Region (MAR) have been under constant and continuing pressure from anthropogenic settlement since before the arrival of the first Europeans on the continent. Disturbances related to human development have impeded the functioning of these ecosystems and reduced the quantity and quality of services they provide to society. An understanding of the detrimental effects of landscape alteration has grown within the past few decades, and in this relatively short period of time, a wealth of research has been compiled on how to reverse these effects through restoration. Floodplains, often heavily settled and modified, have been of particular interest as they provide valuable services such as flood attenuation, soil enrichment, and water storage. Within the context of floodplains, limited attention has been paid to coarse woody debris (CWD) and its role in the ecosystem. Historically, coarse woody debris has been removed from channels and riparian corridors by people for a number of reasons. It is now understood to be a crucial element of ecosystem architecture, and efforts are being made to characterize how CWD dynamics within the landscape affect functioning and service provisioning. Although a body of work on this subject has been produced in the Pacific Northwest of the U.S., there are still many questions that remain to be answered. This research utilizes data collected during rapid field assessments of habitat quality, in conjunction with intensive surveys of debris, to determine how anthropogenic disturbance influences debris abundances and characteristics in floodplain systems. This study was completed in the central Pennsylvania portion of the MAR, an area that, though heavily forested, has received little attention in debris studies. Results demonstrate that the greatest quantities of debris are associated with sites experiencing the least amount of anthropogenic disturbance, and that the debris found at these sites shows greater diversity in size than debris found elsewhere. A moderately-robust mathematical relationship was also established between debris counts and riparian forest basal areas, indicating that this measurement of habitat quality may be the best predictor of debris concentration. These findings have important implications for both ecological integrity and ecosystem service provisioning, and will hopefully enable land managers in the Mid-Atlantic Region to make informed choices regarding debris installations on their properties.

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 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.
