A special form of transition pathway, referred to as a deterministic transition pathway, can be specified for each state, representing a transition that occurs automatically once the age of the simulation cell exceeds the state's upper age limit. Each deterministic transition pathway in a pathway diagram is characterized according to the following fields:

From Stratum

The stratum associated with the source state class of the deterministic transition pathway.

From Class

The unique label (e.g. cover type and structural stage) associated with the source state class of the deterministic transition pathway.

To Stratum

The stratum associated with the destination state class of the deterministic transition pathway. If blank then assumed to be the same as the From Stratum.

To Class

The unique label (e.g. cover type and structural stage) associated with the destination state class of the deterministic transition pathway. To indicate that no deterministic transition pathway exists for the source state class, set the To Stratum and To Class to be the same as the From Stratum and From Class.

Age Min

The minimum age of the source state class.

Age Max

The maximum age of the source state class. Once this age is reached, a deterministic transition will occur to the destination state class. Note that in version 3 or later, if a deterministic transition goes back to the same state class and the maximum age is reached, the age of the cell will remain at the maximum value. In previous versions, the age would be reset to the starting age of the class.

Location

The location in the pathway diagram for this source state class.
