Deriving a tree growth model from any existing stand growth model

A tree-growth model to optimize silviculture

In this paper, we present the description of a simplified model of the dynamic of a mono-specific even-aged forest. The model studied is a tree-growth model based on a system of two ordinary differential equations concerning the tree basal area and the number of trees. The analytical study of this model permits us to predict the behavior of the system solutions. We are trying to highlight the i...

A Tree-Like Model for Brain Growth and Structure

The Flory-Stockmayer theory for the polycondensation of branched polymers, modified for finite systems beyond the gel point, is applied to the connection (synapses) of neurons, which can be considered highly branched "monomeric" units. Initially, the process is a linear growth and tree-like branching between dendrites and axons of nonself-neurons. After the gel point and at the maximum "tree" s...

A New Model for Size-Dependent Tree Growth in Forests.

Tree growth, especially diameter growth of tree stems, is an important issue for understanding the productivity and dynamics of forest stands. Metabolic scaling theory predicted that the 2/3 power of stem diameter at a certain time is a linear function of the 2/3 power of the initial diameter and that the diameter growth rate scales to the 1/3 power of the initial diameter. We tested these pred...

A robust growth model for smallholder tree plantations

Information is a prerequisite for wise forest management decisions, but is inadequate in many situations, especially in the context of small non-industrial forest growers. This paper presents a series of robust functions able be calibrated with sparse data, and integrated into a simple spreadsheet-based growth model designed to assist silvicultural decisions in smallholder plantations. A case s...
