Biogeoclimatic zones and subzones of the Cariboo Forest Region
This report is the result of a specific request by the Cariboo Forest Region for a broad scale reconnaissance stratification of ecological zones for resource management in the Cariboo region. The purpose of the publication is twofold. Firstly an introductory discussion of the Ministry of Forest's approach to ecosystem classification is presented. Secondly, this publication reports on the results of a reconnaissance study carried out on the zones and subzones of the Cariboo Forest Region and briefly outlines the more important physical, biological and resource characteristics of these zones. This represents the first phase of a systematic study to describe the various forest ecosystems of the Cariboo Forest Region for resource managers. It is to be expected that our concepts of zones and subzones will change as the classification of the province becomes more complete.
