This grid holds values for a second growth resource for use by the Double resource relative growth and Growth and Resource-Based Mortality behaviors. The actual identity of the resource is unknown and unimportant. The grid holds a value for resource level in each cell and it is assumed that the units scale appropriately to the parameters for the growth behavior. The grid cell resolution defaults to 8 m X 8 m. You can set whatever new resolution you wish.
Data member name | Description |
---|---|
Resource | Resource amount, in whatever units are appropriate |
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.
