Diameter/basal area increment equations for loblolly pine trees in cutover, site-prepared plantations
… objective of this study was to develop diameter/basal area increment equations for loblolly pine trees in thinned and unthinned plantations on cutover, site-prepared areas. Results indicated that one set of coefficients was sufficient to estimate individual tree growth (for the three year period …

Sensitivity Analysis of the Forest Vegetation Simulator Southern Variant (FVS-Sn)for Southern Appalachian Hardwoods
… FVS-Sn model parameters and predicted 10-year basal area increment. Model sensitivities were calculated for five different test scenarios for both uncorrelated and correlated FVS-Sn input parameters and sub-models. Predicted 10-year basal area increment was most sensitive to parameters and …

Assessing the impact of greentree reservoir water management on red oak growth and anatomy in the lower Mississippi Alluvial Valley
… core samples were crossdated and converted to basal area increment to analyze tree growth. During years of recorded spring flooding, tree growth was not negatively affected. Basal area increment was used to place individual trees into vigor classes, trees in the lowest elevations of the GTRs …

Growth of advanced European beech trees in the transformation phase in the southern Black Forest
… covered the three main tree growth attributes; basal area, height and crown width, and their importance to gap closure simulation. <br> <br>Although some of the specifics of the analyses are lost when generalizations are made, taken all together, the results suggest the following broad …

Impact of Gap Size on Environmental Conditions, Survival, and Early Growth of 5 Pacific Northwest Species
… understory vegetation led to reductions in basal area increment in western redcedar (Thuja plicata), western hemlock (Tsuga heterophylla), Douglas-fir (Pseudotsuga menziesii), and grand fir (Abies grandis). Western hemlock and western redcedar saw increased growth as vegetation cover …

Growth and nutrient relations in black cottonwood in South-Coastal British Columbia
… DRIS norms had the following 3 year responses - basal area increment increased by 65%, and height growth increment by 15% at the Squamish 23 site; basal area increment increased by 65% and height growth increment increased by 30% at the Strawberry site; and basal area increment increased by 27% …

Growth release of trees following fine-scale canopy disturbances in old-growth forests of coastal British Columbia, Canada
… releases using radial-growth averaging. Basal area increment was also the most appropriate growth index for detecting releases. Establishing these empirically-based criteria was important for quantifying the magnitude and duration of releases. Tree diameter and growth rate prior to …

Competitive status of red spruce (Picea rubens) and Fraser fir (Abies fraseri) at ecotonal transitions in southern Appalachian sky islands
… test effects of aspect, cover type, and year on basal area growth measurements of red spruce, Fraser fir, and hardwoods to assess effects of competition. Growth rates were significantly affected by species, aspect, cover type, and year, and generally increased over time. Red spruce growth rates …

Acid deposition effects on soil chemistry and forest growth on the Monongahela National Forest
… FIA sites on the MNF periodic mean annual volume increment (PMAVI) ranged from -9.5 m³ha⁻¹yr¹ to 11.8 m³ha⁻¹yr¹, suggesting lower-than-expected growth on two-thirds of the sites. Growth was compared to soil indicators of acidity on 30 FIA sites. In the surface horizon, effective base saturation …

Stand structure, growth, and mortality in southern Appalachian spruce-fir
… and distributions, stand level foliage surface area (LAI) estimations, and mortality and growth patterns were determined using consistent sampling methodology for a network of 142 (20 m x 20 m) permanent plots at three southern Appalachian spruce-fir sites (Mt. Rogers National Recreation Area …
