Interannual climatic variation mediates elevated CO₂ and O₃ effects on forest growth

We analyzed growth data from model aspen (Populus tremuloides Michx.) forest ecosystems grown in elevated atmospheric carbon dioxide ([CO₂]; 518?LL^-1) and ozone concentrations ([O₃]; 1.5 x background of 30-40 nL L^-1 during daylight hours) for 7 years using...

Comparison of an empirical forest growth and yield simulator and a forest gap simulator using actual 30-year growth from two even-aged forests in Kentucky

Two individual-tree growth simulators are used to predict the growth and mortality on a 30-year-old forest site and an 80-year-old forest site in eastern Kentucky. The empirical growth and yield model (NE-TWIGS) was developed to simulate short-term (

Comparison of yellow poplar growth models on the basis of derived growth analysis variables

Quadratic and cubic polynomials, and Gompertz and Richards asymptotic models were fitted to yellow poplar growth data. These data included height, leaf area, leaf weight and new shoot height for 23 weeks. Seven growth analysis variables were estimated from each function. The Gompertz and Richards models fitted the data best and provided the most accurate derived...

Climate, canopy disturbance, and radial growth averaging in a second-growth mixed-oak forest in West Virginia, USA

This study evaluated the use of radial growth averaging as a technique of identifying canopy disturbances in a thinned 55-year-old mixed-oak stand in West Virginia. We used analysis of variance to determine the time interval (averaging period) and lag period (time between thinning and growth increase) that best captured the growth increase associated with different...

Formulating a stand-growth model for mathematical programming problems in Appalachian forests

Some growth and yield simulators applicable to central hardwood forests can be formulated for use in mathematical programming models that are designed to optimize multi-stand, multi-resource management problems. Once in the required format, growth equations serve as model constraints, defining the dynamics of stand development brought about by harvesting decisions. In...

Diameter-growth model across shortleaf pine range using regression tree analysis

Diameter growth of a tree in most gap-phase models is limited by light, nutrients, moisture, and temperature. Growing-season temperature is represented by growing degree days (gdd), which is the sum of the average daily temperatures above a baseline temperature. Gap-phase models determine the north-south range of a species by the gdd limits at the north and south...

Changes in Eastern Hardwood Sawtimber Growth and Harvest

This article examines increases in eastern hardwood sawtimber volume by species group and species, the utilization of sawtimber by species groups and important eastern species, the utilization of sawtimber by species group by subregion, and discusses issues that could impede future growth of the hardwood timber resource. Eastern hardwood sawtimber volume has nearly...

Stand dynamics in 60-year-old Allegheny hardwoods after thinning

Stand dynamics and tree growth in even-aged hardwood stands can be influenced by manipulating relative stand density, species composition, and stand structure. Land managers need quantitative information on the effect of vegetation manipulation to prescribe stand treatments that are appropriate for specific management objectives. Sixty-year-old stands composed of black...

Coopers Rock Crop Tree Demonstration Area—20-year results

During the 1988/1989 dormant season, the Coopers Rock Crop Tree Demonstration Area was established in a 55-year-old central Appalachian hardwood forest in north-central West Virginia. After treatment, 89 northern red oak (Quercus rubra L.) and 147 yellow-poplar (Liriodentron tulipifera L.) crop trees were monitored for 20 years....

Effect of crown growing space and age on the growth of northern red oak

Cultural practices can be applied in even-age stands to reallocate site resources to selected crop trees. Precornrnercial thinning in sapling stands can increase diameter growth and improve species composition of trees in the main canopy. Commercial thinning in sawtimber stands also increases diameter growth of crop trees, improves residual stand quality, and removes...

Growth and development of planted northern red oak on bulldozed skidroads after clearcutting in Appalachian hardwoods

Artificial regeneration of northern red oak in Appalachian clearcuts on mesic sites is hindered by accessibility and competition from developing vegetation. The use of skidroads as a planting medium was evaluated on two clearcuts with contrasting aspects in north central West Virginia. Stratified acorns were planted in tree shelters at three positions (cut, middle,...

Merchantable sawlog and bole-length equations for the Northeastern United States

A modified Richards growth model is used to develop species-specific coefficients for equations estimating the merchantable sawlog and bole lengths of trees from 25 species groups common to the Northeastern United States. These regression coefficients have been incorporated into the growth-and-yield simulation software, NE-TWIGS.

Effect of stand density and structure on the abundance of northern red oak advance reproduction

Regenerating northern red oak (Quercus rubra L.) on high-quality growing sites is a continuing problem in the central Appalachian region. Competing species usually exhibit faster height growth after regeneration harvests compared to oak reproduction. The probability of advance oak reproduction becoming codominant in the new stand is positively...

Artificial regeneration of northern red oak in the Lake States with a light shelterwood: a departure from tradition

Artificial regeneration of northern red oak is difficult to achieve in the Lake States. A replicated study was established in northern Wisconsin in 1990 to determine the effect of overstory density and understory competition on the performance of bareroot and containerized northern red oak seedlings on a dry-mesic site. The relationship between seedling performance and...

Establishment and characterization of American elm cell suspension cultures

Cell suspension cultures of Dutch elm disease (DED)-tolerant and DED-susceptible American elms clones have been established and characterized as prerequisites for contrasts of cellular responses to pathogen-derived elicitors. Characteristics of cultured elm cell growth were monitored by A700 and media conductivity. Combined cell growth data for all experiments within a...

An evaluation of three growth and yield simulators for even-aged hardwood forests of the mid-Appalachian region

Data from even-aged hardwood stands in four ecoregions across the mid-Appalachian region were used to test projection accuracy for three available growth and yield software systems: SILVAH, the Forest Vegetation Simulator, and the Stand Damage Model. Average root mean squared error (RMSE) ranged from 20 to 140 percent of actual trees per acre while RMSE ranged from 2...

Increment contracts: southern experience and potential use in the Appalachians

Increment contracts are long-term timber management contracts in which landowners receive regular payments based on the average annual growth of wood their land is capable of producing. Increment contracts have been used on nearly 500,000 acres of private forests in the South. Southern experience suggests that several changes in the contract would improve its utility:...
