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 …

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 …

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 …

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 …

Recovery and Resilience of Appalachian Herbs
The herbaceous layer of rich cove forests in the Southern Appalachians represent one of the highest biodiversity habitats in North America. These forests, however, have undergone large-scale logging disturbance that has altered 99% of the original forested landscape, leaving few old growth forests. …

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 …

Long-Term Effects of Forest Harvesting on Habitat Use By Insectivorous Bats
… and eventually disappear with natural forest regrowth. Long-term effects of forest harvesting could thus differ from short-term effects on forest-dwelling bat species. To evaluate changes in habitat use by an insectivorous bat community in response to forest harvesting over time, I repeated a …

Seeing the city for the forest : the transformation and preservation of New York City's old growth urban forest
… trees. The city contains over 10,000 acres of forests within 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 …

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 …

Reestablishing Diversity in Our Hardwood Forests: A Transplant Study of Five Spring-Flowering Herbs
… In the eastern United States, most hardwood forests are growing on land once entirely cleared or used for some form of agriculture. Although some of these forests are nearly 150 years old, they still have depauperate native herbaceous communities when compared to remaining old-growth forests. …

Application of a New Tree-Ring Based Drought Reconstruction Method at Multiple Forest Sites Across Indiana, U.S.A.
… model compared to a single species (SS) in four old-growth forests in Indiana: Pioneer Mothers Memorial Forest (PM), Donaldson Woods (DW), Hoot Woods (HW), and Lilly Dickey Woods (LD). The objectives of this study were to [1] evaluate the climate response of all chronologies (<em>n</em> = 19; 7 …

Earth as Equity Partner: A Revolutionary Approach to Ecological Conservation through Housing Development
… at a time when watersheds, national parks, and old-growth forests are faced with the greatest threat to global ecology. Duddington Farm is used as a retrospective case, but the broader goal is to create a regenerative framework for conservation-based development across critical watershed regions.

Mapping Ancient Baldcypress Forests for Conservation at Black River, North Carolina
<p>A few ancient baldcypress-bottomland hardwood forests survive across the southeastern United States in a mosaic of remnant old-growth stands left untouched by extensive logging during the early 20th century. Uncut stands in the Southeast that survived centuries of disturbance following European …

LiDAR-Assisted Extraction of Old Growth Baldcypress Stands Along The Black River of North Carolina
<p>The remnants of ancient baldcypress forests continue to grow across the Southeastern United States. These long lived trees are invaluable for biodiversity along riverine ecosystems, provide habitat to a myriad of animal species, and augment the proxy climate record for North America. While …

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 …

Evaluating social welfare implications of forestry policies when economic and environmental values matter in a British Columbia context
… timber supply could be managed alongside old growth if only profit and biodiversity matter or in the case where there is a downward-sloping demand for old growth forests.

Flood Processes, Forest Dynamics, and Disturbance In the Congaree River Floodplain, South Carolina
… with the following disturbance history: unlogged old-growth forests, selectively logged forests, and clear cut forests. Forest succession in old-growth environments exhibited a gradual transition from obligate wetland species to facultative species. In contrast, recovery patterns in clear-cut …

Resource selection and abundance estimation of moose: Implications for caribou recovery in a human altered landscape
… and their shared predators. The conversion of old-growth forests to young seral stands is hypothesized to increase the abundance of moose (Alces alces), the dominant prey for wolves (Canis lupus), resulting in apparent competition. We first examined habitat selection of moose in 2 regions with …
