|Developing Stand Density Management Regimes|
Objectives, strategies and tactics form an interdependent hierarchy. Within this framework a decision support process suitable for stand density management planning can be fitted. The process links the structural components with essential analyses and correctly sequenced queries. Figure 13 illustrates the resulting knowledge-based, structured decision support process. It is intended to assist forest planners and silviculturists identifying density management strategies, and in preparing biologically and economically feasible stand prescriptions.
The process begins with clearly defined management objectives, proceeds to the identification of strategic opportunities, and finally to the identification and evaluation of tactical options. The hierarchical structure of the process requires the satisfactory completion of higher level questions before proceeding to the strategic and tactical level. Strategy identification will result in the adoption or rejection of density management as a strategy depending on the results of forest-level analysis. Biological feasibility is the principle determinant of the tactical effectiveness of a density management option. Failing this test results in abandonment of the option, and reiteration of the tactic identification step.
