This harvest forecast is very stable and it is possible that information and practices which improve the volume of regenerated stands can result in an increase in the harvest level across all time horizons. Even if a short-term benefit cannot be obtained, then at the very least one can expect an increase in the future as shown at the point where the small, dotted line departs from the solid black line.

In this situation, changes in information or practices which improve the yields of regenerated stands generally do not affect the short term, but may result in future increases as shown by the small dotted line, or, in a best case scenario, may even offset the fall-down entirely as shown by the dashed line joining the small, dotted line.

In this forecast, changes in information or practices which increase the yields of regenrated stands generally cannot offset the fall-down but may lessen the duration or depth of fall-down as shown by the dashed line, or may not have any benefit until far into the future as shown by the small dotted line.
