Great stuff...I could just see myself in a lecture hall at UBC in the 1970s. Having said all this. Let me add, that this detail is actually not new, but perhaps better understood would be better what to characterize. Most of the things mentioned here were taught in Botany 101, Dendrology and Silvics back in the day....while I have been away from this for many decades...it is nice to get a refresher. Where the rubber hits the road is human demand for forest products and how to acquire those products from the forest and maintain as healthy an ecosystem as possible. Mention of dispersed retention is appropriate in some situations, but certainly not all and due to physical constraints and basic economics is not possible in many others...this should be stressed. Further, the more retention quite possible the more area that will be harvested unless we reduce allowable harvest limits...which has major consequences for a community level of milling, forest investment into milling, employment, the multiplier effect of having a healthy viable forest operation over a certain area. These are the challenges of a professional forester who actually manages forest for economic, social benefit as well as the environment. Sure folks today like to talk about ecosystem services...we can accommodate these by ensuring a large park, and recreation corridors, recognizing the extent and roll of defacto forests which are those we will never consider for timber harvesting for instance. In my view, I do wish folks would limit their use of "resilient" "diverse" and more as they tend to be overused and because these words are nothing without full consideration to context to any specific forest ecosystem, biogeoclimatic zone and subzone.
