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

• Ex. 3 : (Phase 1). Design of a Multi-Strata Stand
• Ex. 3: (Phase 2) Simulating the Herbicide Treatment to the Sw – Herb Strata
• Ex. 3: (Phase 3.) Design the growth projection
• Ex. 3: (Phase 4.) Execute Crop Plan
• Ex. 3: (Phase 5.) Analyze the results

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

   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.

      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)
