Effects of tree leaf litter, deer fecal pellets, and soil properties on growth of an introduced earthworm (Lumbricus terrestris): Implications for invasion dynamics

Invasive earthworm communities are expanding into previously earthworm-free forests of North America, producing profound ecosystem changes. Lumbricus terrestris is an invasive anecic earthworm that consumes a large portion of the detritus on the soil surface, eliminating forest floor organic horizons and reducing soil organic matter. Two mesocosm...

Impacts of drought on tree mortality and growth in a mixed hardwood forest

The tree and shrub species on a 16-ha watershed in the Coweeta Basin were sampled in 1984 and again in 1991 to determine the effects of drought on tree species composition and basal area growth. Mortality and radial growth were determined for tree species within three community types that represent a moisture gradient from moist to dry: covhardwoods > mixed-oak...

Forest tree growth response to hydroclimate variability in the southern Appalachians

Climate change will affect tree species growth and distribution; however, under the same climatic conditions species may differ in their response according to site conditions. We evaluated the climate-driven patterns of growth for six dominant deciduous tree species in the southern Appalachians. We categorized species into two functional groups based on their stomatal...

A comparison of three approaches for simulating fine-scale surface winds in support of wildland fire management. Part II. An exploratory study of the effect of simulated winds on fire growth simulations

The effect of fine-resolution wind simulations on fire growth simulations is explored. The wind models are (1) a wind field consisting of constant speed and direction applied everywhere over the area of interest; (2) a tool based on the solution of the conservation of mass only (termed mass-conserving model) and (3) a tool based on a solution of conservation of mass...

Growth of eastern white pine (Pinus strobus L.) related to forest floor consumption by prescribed fire in the Southern Appalachians

Chainsaw felling, burning, and planting of eastern white pine (Pinus strobus L.) have been prescribed on degraded pine/hardwood stands in the Southern Appalachians to improve overstory composition and productivity. The desired future condition of the overstory is a productive pine/hardwood mixture, with white pine, which is resistant to southern pine...

Effects of competition from young northern hardwoods on red pine seedling growth, nutrient use efficiency, and leaf morphology

The effects of competition from three northern hardwood tree species on red pine (Pinus resinosa Ait.) seedlings were examined on two clear-cut sites in western Maine. We examined how planted red pine seedlings altered their nutrient use efficiency and shoot morphology under changing environmental conditions and how these changes related to their...

Tree and understory responses to variable-density thinning in western Washington.

The Olympic Habitat Development Study was initiated in 1994 to evaluate whether active management in 35- to 70-year-old stands could accelerate development of stand structures and plant and animal communities associated with late-successional forests. The study used a variable-density thinning prescription as the main tool to alter stand structure; the prescription...

Predicting the effects of hardwood competition on red pine seedling growth

Pin cherry (Prunus pensylvanica L.f.) and striped maple (Acer pensylvanicum L.) are potentially important competitors of red pine (Pinus resinosa Ait) planted on recently clear-cut hardwood sites. By experimentally manipulating initial competitor densities on 2.0-m² plots, we were able to...

Forest dynamics following eastern hemlock mortality in the southern Appalachians

Understanding changes in community composition caused by invasive species is critical for predicting effects on ecosystem function, particularly when the invasive threatens a foundation species. Here we focus on dynamics of forest structure, composition and microclimate, and how these interact in southern Appalachian riparian forests following invasion by hemlock...

Lack of forest tree seedling recruitment and enhanced tree and shrub growth characterizes post-Tsuga canadensis mortality forests in the southern Appalachians

The loss of Tsuga Canadensis from invasion by hemlock woolly adelgid (Adelges tsugae, HWA) has altered ecosystem structure and funcition in forests across the eastern United States. In southern Appalachian forests, T. Canadensis co-occurred with hardwood species and an evergreen ...

Site preparation burning to improve southern Appalachian pine-hardwood stands: photosynthesis, water relations, and growth of planted Pinus strobus during establishment

Fire is now prescribed as a silvicultural treatment to restore low-diversity, low-productivity sites in southern Appalachian forests.Eastern white pine (Pinus strobus L.) is then planted on many of these sites to provide a mixed pine-oak forest type (see Swift et al. 1993).Fire reduces sprout vigor, which delays growth of Kalmia latifolia L., a common understory shrub...

Pine regeneration following wildland fire (P-53)

Pine regeneration following wildland fire continues to be a serious problem across the western and southeastern U.S. Frequency of large wildfires has increased over the last several decades and restoration of these burned areas is a major problem confronting land managers. Prescribed fires are used primarily to reduce heavy fuel loads and secondarily to reduce...
