Growth modelling for planning sustainable wood production.
A. G. D. Whyte
This paper provides a brief overview of appropriate growth modelling design, utility and modus operandi for sustainable wood production planning and management. Emphasis is given to outlining integrated inventory, modelling, monitoring and auditing systems that are appropriate for overall planning, controlling and reporting of operational performance and also associated resource outcomes.
A relevant philosophy that is applicable to New Zealand forests which come under Part III A of the 1949 Forests Act as amended in 1993 and which conforms with international agreements and protocols as well as the RMA, is outlined. This philosophy is supported by a few wide-ranging examples that are typical of what might be envisaged. The principal aims are: (i) to indicate the place of growth modelling within the overall management process, (ii) to explain relevant and recommended forms of growth modelling, (iii) to suggest how model predictions can be monitored and controlled and (iv) to provide for ecosystem accountability. Knowledge on how to proceed in principle has been widely known for quite some time within the forestry profession, but the process is not well understood by managers and researchers who have no tertiary qualifications in forestry, nor among most politicians, media journalists and the public at large.
This paper is aimed at professional foresters, however, in the hope that the rationale outlined here can be used by them to help inform stakeholders how wood production forestry in an ecosystem can be made sustainable in their particular situations.
