Event Stand Setting

A number of stand settings are available when establishing a stand.

Input Setting  Description
Stand ID An identifier for the stand. This must be relatively short and can include only characters that are allowed by Excel for use in a worksheet name.
Stand WT The relative area-weighting factor for the stand. Unless a multi-strata stand (MSS) is being established, this value should be '1'. MSS stands are signalled by stand WT < 1.
If the first Establish event in a crop plan has stand WT < 1, then additional Establish events must be inserted below with appropriate stand WT values. The sum of stand WT values for all Establish events must sum to 1.0. For more information see MSS Stands.
Stand Age Stand age at the time of stand Establishment; elapsed time since primary disturbance.For more information see stand and tree ages.
Year Calendar year at stand Establishment
Random Seed Random numbers are used in creating a simulated stand. The random seed is set before simulation of each Establish or Regen event.
Random numbers are used in creating a simulated stand from the tree list parameters chosen in dialogs for most of the Establish events in MGM. The random seed is set before simulation of each Establish or Regen event.
You can set the starting point to a specific value by entering the seed value (less than 1 and greater than 0) yourself. You can also press the "Randomize Seed" button to pick a new seed. Using the same seed lets you reproduce the tree list exactly for comparison scenarios.
Not currently enabled: You can allow MGM to "roll the dice" for you each time the Establish event is executed by checking the "Roll at run-time" checkbox.
Gap Area Loss % The default value is 0%. When the value is > 0% , the tree density/ha is distributed within the stocked area for the growth projection (internally this means a higher density/ha when computing competition). Following projection the attributes expressed on a per hectare basis are recomputed based on the entire area.
The default value is 0%. When the value is in the interval (0, 100%), the tree density/ha is distributed within the stocked area for the growth projection (internally this means a higher density/ha when computing competition); following projection the future per hectare attributes are scaled back to the entire area. A drop-down list is provided with suggested entry values, but any value may be entered directly; note that entering an unreasonably large value could lead to strange results.
