Virgin hardwood forest soils of western North Carolina
… virgin soils and associated southern Appalachian hardwood vegetation were studied in western North Carolina. The study sites ranged in elevation from 720 to 1200 m on steep slopes. Overall these soils are quite deep and highly weathered due to high rainfall (>200 cm) and soluble feldspathic parent …

Municipal wastewater effects on nitrogen cycling in a mature hardwood forest
… on the structure and function of an Appalachian hardwood forest in Virginia was investigated. Four irrigation rates (17.5, 35, 70, and 140 em yr⁻¹ ) were applied in this hardwood forest, and their effects on forest nutrient cycling were monitored for two years. Tree growth, seedling reproduction, …

Chinese Tallow Long-Term Impact on Stand Dynamics in a Bottomland Hardwood Forest Following Vegetation Management
… known to have negative impacts on bottomland hardwood forests. Chinese tallow is proficient in reproducing and surviving in bottomland hardwood forests because it is more flood and shade tolerant than most native trees. The long-term effectiveness of Chinese tallow control is an important …

NATURAL REGENERATION DYNAMICS AND SURVIVAL INFLUENCED BY ABIOTIC AND BIOTIC FACTORS IN A BOTTOMLAND HARDWOOD FOREST
… support, and aesthetic value. Bottomland hardwood forests, however, are threatened by invasive species, land loss/conversion, inconsistent or absence of harvesting disturbances, and altered hydrological patterns, leading to reduced success of desired, native species. This research assessed …

Quantifying bottomland hardwood forest and agricultural grassland evapotranspiration in floodplain reaches of a mid Missouri stream
Bottomland hardwood forests (BHF) play an important role in floodplain dynamics, particularly along urban streams where flood mitigation is critical to protecting human life and property. Enhanced evapotranspiration (ET) of riparian floodplain forests could help reduce flooding through drying of …

Impact Of Timber Harvest On Mercury Mobilization In A Mixed Pine And Hardwood Forest And Adjacent Lake In Mississippi
With 65% of land area covered in forest, Mississippi is a leader in the timber industry. Whereas forestry provides numerous benefits for humans and wildlife, forest harvest has been hypothesized to increase mercury (Hg) mobilization to aquatic systems. In a forest, Hg mostly accumulates in the …

Assessing ice storm damage to hardwood forest canopies using the Advanced Solid-State Array Spectroradiometer (ASAS) and Landsat TM imagery
… in January 1998 damaged 17 million acres of forestland in the Northeastern United States and Quebec Province. In July 1998 the airborne multiangle hyperspectral sensor, Advanced Solid-State Array Spectroradiometer (ASAS), acquired imagery for nine ice damaged target areas in the White …

Modeling the Distribution of the Northern Hardwood Forest Type in Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus) Recovery Areas of the Southern Appalachians
The northern hardwood forest type is a critical habitat component for the endangered Carolina northern flying squirrel (CNFS; Glaucomys sabrinus coloratus) for denning sites and corridor habitats between montane conifer patches where the squirrel forages. This study examined terrain data, and …

HERBIVORY IMPACTS ON GROWTH AND SURVIVAL OF SEEDLINGS IN BOTTOMLAND HARDWOOD FOREST RESTORATION SITES IN THE POST OAK SAVANNAH AND BLACKLAND PRAIRIE ECOREGIONS OF TEXAS, USA
<p>Interest in bottomland hardwood forests (BLHW) ecology and restoration has increased over the past 40 years. These communities aid in water quality improvement, streambank stabilization, and urban expansion mitigation. They also provide important habitat for many species of wildlife. Since the …

Estimating above and below ground vegetation biomass and carbon storage across an intra-urban land-use gradient in mid-Missouri
… on vegetative communities can widely vary. Urban forests play a vital role as carbon sinks for atmospheric carbon dioxide. In order to further understanding of the impacts of urbanization on vegetative communities and carbon storage six intra-urban 50m2 plots were surveyed for vegetation …

Assessment of small mammal populations in two Southeastern forests of Big Ridge in Chattanooga, TN
… sites were chosen in old growth and mixed hardwood forest areas. Six day sampling periods consisted of differing densities and setups of Sherman and pitfall traps within 0.16-ha plots. Data was not statistically analyzed due to minimal sample sizes. Comparable 1.28-ha mixed hardwood forest …

A range-wide disturbance history for Quercus alba in the eastern US
Throughout much of the eastern US, forests are undergoing a transition from Quercus to Acer-Fagus dominance. While the pattern has been reported in many site-specific analyses and is often linked to changes in disturbance regimes, a landscape-level analysis of historical establishment and …

Territoriality and habitat selection of feral pigs on Fort Benning, Georgia, USA
… five land cover types (open grassy areas, upland hardwood forest, pine forest, pine-hardwood forest, and hardwood bottomland forest) based on differences in the food and cover resources they provided feral pigs and used Ivlev's index to evaluate habitat use within sounder home ranges. Sounders had …

The Distributional Ecology of Three Uncommon Salamanders in Iowa
… All three species were dependent upon mature hardwood forest and temporary or permanent ponds. "A. texanum" was found primarily in lowland forest. The other two species inhabited both lowland and upland forest. Larval "A. tigrinum" may be a significant predator of "A. texanum" Larvae in Iowa.

Riparian Forest Width and the Avian Community in a Greenbelt Corridor Setting
The forest avian community of the Ray Roberts Greenbelt (Denton Co., Texas) was characterized for two years using point count station sampling, from fall 1998 to summer 2000. Richness data for both breeding seasons were correlated with two-spatial metrics: width of the riparian forest and distance …
