Biogeochemical Investigations in Old Growth and Disturbed Forest Sites at Mount Kilimanjaro
… clearings had higher sand contents, the water holding capacity of these sites was lower than in the mature forest. With the exception of NO3-N in the forests, all nutrients in rainfall were increased upon passage through the forest canopy, but nutrient fluxes in rainfall as well as throughfall …

Regeneration Dynamics in Old -Growth and Second-Growth Southern Appalachian Cove Forests
Regeneration dynamics in an old-growth and a second-growth cove forest in the Great Smoky Mountains of eastern Tennessee were studied over the course of four contiguous growing seasons. Woody shrub and herbaceous species in the regeneration layer were also investigated. The effects of disturbance …

Vegetation Dynamics of an Old-growth Mixed Mesophytic Forest in Southeastern Ohio, USA
… the second sampling effort at Dysart Woods, an old-growth, mixed-mesophytic remnant tract in southeastern Ohio. In 2011, trees, saplings, shrubs, herbs, and soils were sampled in permanent plots established in 1996, allowing a direct fifteen–year comparison. Mortality and recruitment rates …

Carbon Storage in Old-Growth Western Larch (Larix occidentalis) Forests of Western Montana
… 30 years, the structural development of western old-growth ecosystems has been of great interest in ecological research. As the loss of historical forested acreage in western Montana became more widely recognized, the preservation of frequent-fire old-growth stands became a focus of forest …

The status and distribution of terrestrial amphibians in old-growth forests and managed stands
… the abundance of terrestrial amphibians in old-growth forests and young and mature post-harvest stands. I also examine the habitat features with which they are strongly associated, and contrast these between old growth and second growth to gain insight on the specific effects of logging …

LiDAR-Assisted Extraction of Old Growth Baldcypress Stands Along The Black River of North Carolina
… which are estimated to be more than 1,000 years old, LiDAR remote sensing and geospatial analysis techniques can be employed. Promising results have been discovered correlating LiDAR-derived metrics and known stands of old growth baldcypress. A number of percentile height metrics and other …

Implicit Environmental Value of Old Growth on the United States National Forests in Western Washington
… 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 1976 …

Applications of ecological modeling in managing Central Appalachian upland oak stands for old-growth characteristics
Old-growth forests provide important habitat for wildlife, support the maintenance of biodiversity and serve as control areas for scientific research. Expanding current old-growth stand area by utilizing neighboring younger, managed stands allows private landowners to meet management needs and …

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 …

The Development Of Old-Growth Structural Characteristics In Second-Growth Forests Of The Cumberland Plateau, Kentucky, U.s.a.
… state 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 …

Age, forest structure, and disturbance history of five potential old-growth forests in eastern Kentucky's Cumberland Plateau
… of global importance, yet its extent of old- growth forest (OG) is not well known. Due to its rarity and importance, understanding what OG remains is needed to deduce the region's health. This study described five potential OG forests in eastern Kentucky. Sites possessing >5 trees/ha …

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 …

Growth release of trees following fine-scale canopy disturbances in old-growth forests of coastal British Columbia, Canada
Growth release of trees following canopy disturbances is of interest to ecological scientists and forest managers. Using dendroecological techniques, I examined growth release of canopy and subcanopy trees following the formation of natural, fine-scale canopy gaps in old-growth, western red …

Seeing the city for the forest : the transformation and preservation of New York City's old growth urban forest
… the five boroughs, including several examples of old growth forests. These natural areas are at risk--from their vulnerability to climate impacts, to development pressures, to a lack of support for and information about managing urban forests. Urban forests will only become more crucial to quality …

Forest structure in unharvested old-growth: understanding the influence of soils on variability of long-term tree dynamics and fire history
… (CFLRP) provides guidelines for community stakeholders and private advocacy groups to engage with federal, state, and local agency stewards to develop monitoring and assessment goals for forest restoration projects. The Uncompahgre Plateau (UP) was identified as one of ten initial CFLRP locations …

Natural Environmental Gradients Predict The Microhabitat Use, Fine-Scale Distribution, And Abundance Of Three Woodland Salamanders In An Old-Growth Forest
… at forty 0.08‐ha sample plots within a ca. 42 ha old‐growth forest in the Cumberland Plateau region of southeastern Kentucky. This study finds that patterns of microhabitat use, occupancy, and abundance of P. richmondi and kentucki reflected physiological restraints associated with desiccation …

Heterogeneity of Stand Structure, Fuels, and Wildfire Hazard in Dry and Moist Old-Growth Ponderosa Pine Forests: Case Studies from Western Montana
… and remediate catastrophic wildfire hazards in old-growth ponderosa pine stands throughout the western United States. However, stand heterogeneity has been inadequately addressed in restoration and fuel treatment planning. In response, we analyzed two old-growth ponderosa pine forest restoration …
