Constant radial growth

Parameters for these behaviors

Parameter nameDescription
Adult Constant Radial Growth in mm/yrThe constant value by which to increase a tree's radius at breast height.

How it works

The amount of diameter increase is calculated from the constant radial increment. The increase is calculated as follows:

Y = (g4 / 10) * 2 * T


  • Y is the amount of diameter growth, in cm, to add to the tree
  • g4 is the Adult Constant Radial Growth in mm/yr parameter
  • T is the number of years per timestep

Note that the increment parameter specifies radial growth; the behavior makes all necessary conversions to diameter growth.

How to apply it

This behavior can be applied to seedlings, saplings, and adults of any species. Any tree species/type combination to which it is applied must also have a light behavior applied. You can use either the diam with auto height or diam only version.
