Habitat
Wide range, including wet depressions; re-colonizes burned areas (B002) It is likely that elevations above 600m in the NWT will have trees that are mostly lodgepole pine (working in a decrease of equivalent elevation with increasing latitude of about 0.5m per km - a relation which seems to hold in the mountains of NWT and Alberta) (D Downing H225).
