Substrate Grid

This grid is created by the Substrate behavior. The grid holds the relative proportions of the various substrate types. If the Harvest behavior is present for the run, then this grid's resolution must match the Harvest Results grid. Otherwise, it defaults to a cell resolution of 8 m X 8 m, which you can change. This grid holds packages with a different data structure from the main grid to track Substrate cohorts.

Data in the grid

Data member nameDescription
Proportion of scarified soilThe proportion of the grid cell area that is scarified soil

Proportion of tip-up moundsThe proportion of the grid cell area that is tip-up mounds
Proportion of fresh logsThe proportion of the grid cell area that is fresh logs
Proportion of decayed logsThe proportion of the grid cell area that is decayed logs
