Abstract
Ecological and planning studies were carried out to develop and demonstrate a new method for integrated management of a forest resource. This method, combining an ecosystematic approach and a new subunit planning procedure, was applied to the Koprino River watershed on Vancouver Island.Following an analysis, forest ecosystems were classified according to the taxonomy proposed by Krajina and his students. Eighteen associations, divided into 26 types, were recognized in the watershed. These biogeocoenotic taxa were integrated for practical application into fourteen treatment units which were subsequently mapped at the scale of 1:20 000. Each treatment unit was designated by a numerical symbol and a selected color to convey ecosystem productivity and sensitivity. For resource planning a resource management map at the scale 1:20 000 was prepared using the treatment unit map as a base. To guide forest harvesting, the watershed was subdivided into seven resource management areas, each with a specific combination of resource values and management prescriptions.
