This model uses a population submodel to represent the trees in a forest stand. A simple, single-compartment model is used to simulate the growth of each tree, and this is summed outside the submodel to give the total volume of the stand of trees. The model also sets the initial number of trees in the population, the rate at which new trees are created, and the rule for killing off trees when they reach a certain size.
The graphs show the growth of each tree, from birth to death, and the volume of the whole stand. The custom “lollipop diagram” represents the stand structure during the simulation, using the tree’s (x,y) coordinates to position the trees.
