Habitat use by wintering passerines in fire-managed forests along the U.S. Gulf Coast
… as a wintering area, and some depend on habitats managed by fire. To provide information for land managers, I studied the winter bird community at Naval Live Oaks in Gulf Islands National Seashore with two primary objectives: (1) to describe the distribution, abundance, and diversity of the …

Amphibian and Reptile Community Responses to Forest and Riparian Disturbance
… buffers; SMZs) are commonly implemented within managed forests to protect water quality, but may also provide habitat for riparian-associated wildlife. Yet, little research has rigorously addressed the value of SMZs for wildlife, particularly cryptic species such as amphibians and reptiles. …

Exploring the Interaction of Forest Management and Climate in the Community Land Model
Forests perform many important ecological functions and provide numerous environmental services to humanity. Currently forests are under ever increasing pressures from humans through deforestation, changes in land use, and anthropogenic climate change. Managed forests play an important role in …

Population Dynamics of Ouachita Dusky Salamanders (Desmognathus brimleyorum) in a Managed Forest Landscape
… alteration of landscapes increasing world-wide, managed forests are increasingly important as providers of ecosystem services including habitat for numerous wildlife species. It is crucial to maintain a balance between timber production and conservation of biodiversity on managed landscapes. …

Interactive effects of wildfire and disturbance history on amphibians and their parasites
… for future conservation efforts, especially on managed forests. Using data from several wildfires that burned between 1988 and 2003 in and next to Glacier National Park, Montana, I examined how fire affected the distribution, abundance, and infection status of 3 native amphibians. In Chapter 1, …

Environmental and economic assessment of alternative transportation fuels
… Woody biomass harvested from old-growth forests produces a large carbon debt when used as a feedstock for transportation fuel. Managed forests are an attractive alternative for inexpensive biomass production with the potential to reduce this carbon debt. We study the effect of forest …

A comparison of floristic diversity in old-growth versus mid-successional secondary-growth hardwood forests of the White Mountain National Forest, New Hampshire, United States
<p>There is currently debate over whether managed forests will ever regain the species diversity of old-growth stands. While succession and response to disturbance of tree species has been extensively researched, little similar effort has focused on understory herbaceous communities. This study …

Forest Stewardship Council certification of public forests: five case studies
… impact of FSC certification of Colorado's public forests. This issue is especially pertinent to Colorado green builders who are attempting to acquire structural lumber from sustainably managed forests within a 500 mile (805 km) area of the construction site, as prescribed by US Green Build …

Influence of Varying Inorganic Nutrients Supply on Ergosterol and Glucosamine Concentrations and Biomass Nutrient Stoichiometry in Ectomycorrhizal Fungi
… potential to act as carbon sinks in properly managed forests.</p>

The effect of native forest dynamics upon the arrangements of species in oak forests-analysis of heterogeneity effects at the example of epigeal arthropods
… spiders was studied in a natural forest and in a managed forest. Additionally the effects of small-scale microhabitat heterogeneity of managed and unmanaged forests were determined by analysing the spider assemblages of three different microhabitat structures (i. vegetation, ii. dead wood. iii. …

Ecology of Upland Snake Communities in Managed Montane Longleaf Pine Habitats of Georgia
… and species level ecology of snakes in these managed forests. Data for snakes in the montane (mountain) longleaf pine habitats remains unclear since management practice implementation. Currently, intensive restoration of montane longleaf pine habitats is taking place within two Wildlife …

Potential of above- and below-ground coarse woody debris as a carbon sink in managed and unmanaged forests
… is of important public and political interest. Forests represent important terrestrial C sinks. Their management can have direct and indirect influence on forest characteristics, including to some extent C sequestration. One direct effect of forest management is an increase in the stock of …

Quantification and Physiology of Carbon Dynamics in Intensively Managed Loblolly Pine (Pinus taeda L.)
… an understanding of C sequestration capacity in managed forests. Objectives of the first study included (1) investigating environmental, soil C, root, and stand influences on soil CO2 efflux on the South Carolina coastal plain and (2) quantifying soil CO2 efflux over a rotation in loblolly pine …

Loblolly Pine and Soil-Site Responses to Harvesting Disturbance and Site Preparation at Stand Closure
Intensively managed forests of the Southern United States are among the most important sources of wood fiber and timber in this country. There is a great deal of concern that disturbances associated with trafficking by heavy machinery might diminish long-term soil-site productivity. However, …

The Management of National Forests of Eastern United States for Non-Timber Forest Products
Many products are harvested from the forests of the United States in addition to timber. These non-timber forest products (NTFPs) are plants, parts of plants, or fungi that are harvested from within and on the edges of natural, disturbed or managed forests. Often, NTFPs are harvested from public …

The Short-term Effects of Fertilization on Total Soil CO2 Efflux, Heterotrophic, and Autotrophic Respiration of Loblolly Pine (Pinus taeda L.)
… for increasing forest productivity within managed forests of the southeastern United States. However, little is known about how fertilization affects the below-ground processes that drive soil CO2 efflux in loblolly pine (Pinus taeda L.). A thorough understanding of below-ground carbon …

Bats and trees in a managed forest
Many North American bat species rely heavily on forests for roosting and foraging habitat. Especially in the face of drastic population declines, understanding how forests can be managed to support local bat assemblages is crucial for bat conservation. We worked in two managed hardwood state …

Soil Carbon Dioxide Efflux in Response to Fertilization and Mulching Treatments in a Two-Year-Old Loblolly Pine (Pinus taeda L.) Plantation in the Virginia Piedmont
… practices on the carbon dynamics of intensely managed forest ecosystems. Soil carbon dioxide efflux resulting from soil microbial activity and root respiration is one of the major components of the total carbon flux in forested ecosystems. In an effort to examine the response of soil carbon …
