Book Description
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 Description
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 Description
Volume 5 of "If Rails Could Talk¿.Ravensford and Smokemont" is the fifth of a planned eight volume series about the railroad logging along the Blue Ridge and adjoining Smoky Mountains. At 236 pages, volume 5 is the largest book thus far in the series. The decision was made to combine the stories of Ravensford and Smokemont into one book. Volume 5 begins with the story of the 33,000 acre Ravensford timberland, the Appalachian Railway, and the West Virginia company named Parsons Pulp & Lumber that first owned all of it. By 1918, the Champion Fibre Company became the largest landowner in the Great Smokies. Champion's nearly 93,000 acres adjoined the Ravensford lands. Champion Fibre built a fascinating network of standard and narrow gauge railroads to harvest their timber, beginning with their Ocona Lufty Railroad. The book contains many photographs. It also contains beautifully colored track maps of all of the railroad grades, those built and those that were planned but never built. Ron Sullivan and his wife Marilyn hiked most of the abandoned railroad grades out of Ravensford and Smokemont. Co-author Gerald Ledford joined them on many of the hikes as well. Ron mapped all of the grades using a GPS device and drew most of the maps included in the book. The book also contains sections of historical maps long buried in archives that most readers will appreciate. Gerald Ledford had previously interviewed a few of the veterans of both logging operations several decades ago. He also had 2 great uncles who worked in the sawmill at Ravensford. Also featured are the stories of the court battles between Champion Fibre and Ravensford Lumber with the park commissions of Tennessee and North Carolina over the value of their 125,000 acres of land. It is common knowledge that these lands eventually became included in the Great Smoky Mountains National Park. However, many readers will be unfamiliar with the stories included in the book of the messy and at times contentious process to arrive at a settlement.
