The Development Of Old-Growth Structural Characteristics In Second-Growth Forests Of The Cumberland Plateau, Kentucky, U.s.a.
… meeting one or more of the definitions of old-growth forest in use today. However, many recovering, mature forests currently exist that might be redeveloping old-growth structure and function. To assess the development of old-growth forest characteristics in second-growth forests, 70 - 90 year …

Bat Species Diversity in Old-Growth vs. Second Growth Forests in Lilley Cornett Woods, Letcher County, Kentucky
<p>Bat activity in old-growth forests (+150 years) is a subject that is poorly understood. The majority of old-growth forests are located in the northwestern portion of the United States, and with current silviculture practices, many forests are being cut. There have been no published studies that …

Deadwood Dynamics: A Case Study at Prince William Forest Park, Virginia
… to rapidly estimate deadwood of long unmanaged second growth forests to help inform future management decisions. Management agencies within this region, such as the National Park Service, may benefit from a greater understanding of the potential factors that influence deadwood accumulation, …

Implicit Environmental Value of Old Growth on the United States National Forests in Western Washington
… for the value of total non-timber services in second growth forests, and public managers have considered the significant role of old growth to its environment and ecosystem. The result of structural change test, however, illustrates that the introduction of the National Forest Management Act of …

Coarse Woody Debris in Industrially Managed Pinus taeda Plantations of the Southeastern United States
… Most CWD research has been conducted in old-growth and unmanaged, second-growth forests. However, less is understood about CWD in intensively managed ecosystems, such as industrialized southern pine plantations. The objectives of this study were to determine the climatic and ecological …

Local and landscape scale effects of fragmentation on aerial insectivorous bats in the Amazon
… diversity exhibited degradation in the secondary forest matrix around the smallest fragments compared to continuous forest. This negative effect became less pronounced as fragment size increased and in contrast, forest edges generally contained higher diversity. We only found subtle …

Stand dynamics and disturbance history of five oak -dominated old -growth stands in the unglaciated Appalachian Plateau
… histories of five eastern, oak-dominated old-growth stands were investigated using ecological field sampling techniques, dendrochronologogical methods, and a review of historical resources of original forest composition and patterns of human and natural disturbance. Witness tree tallies from …

Land snail species diversity and composition between different forest disturbance regimes in central and eastern Kentucky Forests
… and habitat fragmentation. Because of this, old-growth forests have the potential for being premiere habitat for these organisms, and snails have the potential to be good indicators of old-growth habitats. This study compared land snail species diversity and community composition in old-growth …
