Ex. 3: (Phase 2) Simulating the Herbicide Treatment to the Sw - Herb Strata

This phase of crop plan design deals with adding events to simulate the application of herbicide to the Sw - Herb Strata.

  1. Click the Move Down to Next Event button () to activate the Grow event.
  2. Click the Insert Event button (), select Thin and press OK to open the Thinning dialog
    Species - Dec
    Min DBH - -1
    Removal Rule - With the Largest Diameter Trees First
    Removal Amount Rule - Remove a fixed % of Density
    Amount - 100
    MSS Sub-Stand - Sw - Herb
  3. Click OK when all entries are correct.
  4. Right-click the first Grow event
  5. Click the Edit button () to activate the edit dialog.
    1. Enter stand ages 15 16 17 18 19 20 in the Grow to box. These are the stand ages at which yields will be calculated.
    2. Click the Single growth Schedule option button if it is not already set.
    3. Click OK when all entries are correct.
  6. Click the Move Down using the Next Event button () to activate the End event
  7. Click the Insert Event button (), select Regen and press OK to open the Regen dialog.
    1. Click on the Trees (Stand <= 25 years) Tab.
    2. Set - Stand Settings
      Stand ID - Sw-Herb
      Stand Wt - .6
      Age should be okay at 20!
      Random Seed - sets a starting random number if you choose, for our example it should read - 0.2905
      Gap Area Loss % - 20
    3. Choose Stand Origin as PerfSurveyAllTrees.
    4. Site index - 16
    5. Tree Characteristics

      Species - Aw
      Av Density/ha - 3400
      Av Tree Age - 6
      Av Ht - 1.6
      stDev Ht - 0.3
      Max Ht - 2
      Av DBH - 0.4

      stDev DBH - 0.4

    Press the Add button in the Tree List Parameters box.

    Note: notice the DBH and StDev DBH were changed to (.5 and .12) to better represent the average condition

    Click OK when all entries are correct.

    Note: MGM will warn you that your StandWt is less than 1.0 so respond yes to proceed

  8. Click the Move Down to Next Event button () as needed to activate the End event (highlighted in yellow)
  9. Right-click the End event to insert a Record Stand event immediately after the thin event.
    1. Click the Insert Event button on the MGM Toolbar or the shortcut menu (right-click on the event to display this menu).
    2. Select Record Stand.
      MGM MSS-CP sub-stands list dialogue - choose ALL
    3. Click OK.
  10. Save the Crop Plans worksheet by clicking on the MGM Toolbar Save button () (not the Excel save button!).
  11. The following table should be similar, but not necessarily identical, to the plan you have just created.
