Individual Tree-Based Diameter Growth Model of Slash Pine in Florida Using Nonlinear Mixed Modeling

An Annual Tree Survival and Diameter Growth Model for Loblolly and Slash Pine Plantations in East Texas

An annual growth model that predicts individual tree survival and diameter growth was developed for loblolly pine (Pinus taeda) and slash pine (Pinus elliottii) trees in East Texas as a function of individual-tree diameter, plantation age, basal area per acre, dominant height, quadratic mean diameter, and presence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme)....

Nonlinear mixed modeling of basal area growth for shortleaf pine

Mixed model estimation methods were used to fit individual-tree basal area growth models to tree and stand-level measurements available from permanent plots established in naturally regenerated shortleaf pine (Pinus echinata Mill.) even-aged stands in western Arkansas and eastern Oklahoma in the USA. As a part of the development of a comprehensive distance-independent individual-tree shortleaf ...

Individual Tree Diameter, Height, and Volume Functions for Longleaf Pine

Currently, little information is available to estimate individual tree attributes for longleaf pine (Pinus palustris Mill.), an important tree species of the southeastern United States. The majority of available models are local, relying on stem diameter outside bark at breast height (dbh, cm) and not including stand-level parameters. We developed a set of individual tree equations to predict t...

Intensive Cultural Practices Increase Growth of Juvenile Slash Pine in Florida Sandhills

Genetic Diversity between Two South Florida Slash Pine Populations

South Florida slash pines provide an important microhabitat for some native Florida species, however, less than 1% of the original slash pine forest remains due to deforestation and hurricanes (DERM, 1995). This population decline makes it essential to study the genetic diversity of the remaining pine forest. Therefore, in this study we tested the hypothesis that geographic isolation has led to...
