Editing Treatment Schedules

The scheduler provides a means to automatically generate treatment schedules, but what about making manual adjustments to incorporate 'expert' decisions? The Treatment Viewer provides an interactive mechanism to apply, select and alter proposed management treatments within individual blocks.

To access the Treatment Viewer, highlight the block layer in the MapViewer legend, and right click on a block in the Map Viewer. A pop up menu of options relating to the specific block will be made available, and select View and Edit Treatments to open the Viewer.

The Treatment Viewer has two main components: (see Figure 61, “Treatment Viewer”) the upper portion contains a line chart that depicts growth and yield curves and treatment timings, and the lower portion that contains a list of values showing all of the attributes that are recorded for the block, divided by managed and unmanaged stand information. If a block is composed of exclusively managed or exclusively unmanaged area, only one column of attribute values will appear.

Figure 61. Treatment Viewer

Each attribute listed in the bottom portion of the Viewer has a corresponding curve in the above line chart. The corresponding attribute values will be highlighted in red when the mouse is following the curve in the line chart. The X axis of the line chart represents the years of the planning horizon. As the mouse is moved along a curve in the line chart the attribute values are updated to display the corresponding value for that year.

You can view the line chart to see the development of block attributes through time. Right click in the line chart area to obtain a menu of available treatment options. If there are not treatments available (perhaps the block is an unmanaged type, or it is beyond operability limits) an N/A symbol will appear.

The line chart shows values for the unmanaged portion of the block in red, and values for the managed portion in green.

The numbers in the lower portion of the viewer show the values of the attributes as they change through time. To change the values in the table move the cursor along the X-axis of the line chart. The numbers in the lower panel will be updated to show the forecast for the selected future time period.

The line chart also shows the timing of treatment options as vertical yellow lines. The numbers listed beside the vertical lines represent the product values that result from the application of the treatment. The timing of the treatment can be adjusted by dragging the vertical line to the left or right. The treatment editor will only permit the movement of the treatment timing within eligible date ranges (according to the early and late operability limits associated with the treatment).

Options to add and delete treatments can be accessed by right-clicking within the line chart. Available treatments are displayed in a popup menu, or "N/A" is displayed if no treatements are eligible at that timing. Be aware that as you add treatments you may cause later scheduled treatments to become ineligible, and they may be removed from the schedule. To apply a treatment to the block, right click in the line chart at the desired year and choose the treatment from the menu that appears. A treatment will be represented by a vertical yellow line. The values for the products derived from the treatment will be printed to the right of the yellow line. Treatments can be shifted through time by pressing on the yellow line with the mouse and dragging the line to the left or right. The product values will automatically update. You may remove treatments by right clicking to the right of the treatment i.e. on a timing that is later than the treatment of interest, and selecting Delete Treatment.

[Important]The paradox of time travel!

If you delete a treatment you will alter the future development characteristics of the block. Consequently, future proposed treatment (ie. second rotation treatments) may no longer be viable and will also be removed from the treatment schedule.


While you are viewing block characteristics in the Treatment Viewer the scheduler is locked out from making changes to the block. Once you close the treatment viewer, the block is again eligible for automated scheduling. If you want to ensure that manual decisions are not reverted or overridden by the scheduler you must mark the blocks as being unavailable for scheduling. Do this by clicking on the box in the "AVAILABLE" column in the block attribute table, making sure it is unchecked for that block. See the section called “Adjusting Block Eligibility using the Timing Constraint Editor” for more information on how to adjust block availability.
