Chinese Tallow Long-Term Impact on Stand Dynamics in a Bottomland Hardwood Forest Following Vegetation Management
… examined Chinese tallow and native tree stand structure. Each native and Chinese tallow plot included three sets of nested subplots. The nested subplots include one overstory, one sapling, and four seedling subplots. R (v4.3.3) software was used to run repeated measures analysis of …

Past precipitation, watershed characteristics, and drought: interactive effects on watersheds of Northern California.
… soil type, vegetation composition, and stand age, are known to impact runoff through differences in evapotranspiration and storage. Drought may further change the hydrological function, or precipitation-runoff relationship of a watershed. In this study, I investigated how watershed …

Sensitivity Analysis of the Forest Vegetation Simulator Southern Variant (FVS-Sn)for Southern Appalachian Hardwoods
… and untested model. These limitations notwithstanding, FVS-Sn once tested and validated could meet the critical need of a comprehensive growth and yield model for the mixed hardwood forests of the southern Appalachian region. In this study, sensitivity analyses were performed on the FVS-Sn …

Modeling maximum size-density relationships of loblolly pine (Pinus taeda L.) plantations
… quantifies the reduction in tree numbers due to density-dependent mortality. Maximum size-density relationships (MSDRs) are a component of self-thinning that describe the maximum tree density per unit area obtainable for a given average tree size, often quadratic mean diameter (D). An MSDR …

Stand Density Management for Optimal Volume Production
The relationship between volume production and stand density, often termed the 'growth-density relationship', has been studied since the beginnings of forestry and yet no conclusive evidence about a general pattern has been established. Throughout the literature claims and counterclaims concerning …
