We present refinements made to a previous project on defining and ranking old forest in the Prince George Forest District by relative quality. Six intrinsic indicators and five additive indicators were used to rank old forest polygons (>120 years old or >140 years old) into six quality classes. This ranking was done at both the forest district scale and the BEC Zone scale. The model was run with only the intrinsic indicators, intrinsic plus some additive indicators, and a full model with all intrinsic and all additive indicators included. We report the percentage of old forest by quality rank within each merged NDU/BEC unit, for the full model run at the BEC Zone scale. Finally, we offer recommendations on the application of this model to forest management.
