Document Summary

Best approach is to know what the options are and possible explanations. Why is a dairy bush species not in the arboretum or northern ontario: understand what the options are, it was in other places but not there anymore: local disappearance (extirpation). Fossil or historical records (it was here but disappeared) Plant one there and see if it could live there. They were here but moved away, conditions may have changed and they moved away (range shift) Couldn"t live there even if they arrived. Maybe haven"t arrived, no method for dispersal. Could live here and potentially do but can"t establish here because something stops them from succeeded from other things already living there. A species has a range tolerance to which we can survive eg coldest to hottest temperatures we can survive. Within that range, there"s an optimum which are quite suitable for the survival of that species: where they do best, survival is highest.
