NCI infection effects


Infection effect

Parameters

Infection Effect "a"The "a" parameter for the infection effect.
Infection Effect "b"The "b" parameter for the infection effect.

How it works

Infection Effect is calculated as:

Infection Effect = a * ln(T) + b

where:

Time infested comes from either the Density Dependent Infestation or Insect Infestation behaviors. Trees to which this behavior is applied must have one of these two behaviors also applied.

If a tree is not infested, there is no effect.

NCI infection effects


Size Dependent Infection effect

Parameters

Infection Effect "a"The "a" parameter for the infection effect.
Infection Effect "b"The "b" parameter for the infection effect.
Infection Effect "X0"The "X0" parameter for the infection effect.
Infection Effect "Xb"The "Xb" parameter for the infection effect.
Infection Effect "Xp"The "Xp" parameter for the infection effect.

How it works

Infection Effect is a function of the size of the tree and the time since infested. It is calculated as:

where:

Time infested comes from either the Density Dependent Infestation or Insect Infestation behaviors. Trees to which this behavior is applied must have one of these two behaviors also applied.

If a tree is not infested, there is no effect.
