my friend who works in he forests say about this piece, New Mapping in title but no map. Notes that it's hard to say how big the area is because no mapping. Hemlock/ balsam forest in picture called Yellow cedar forest. Notes decline started around 1800 but claims it is now because of global warming- what was the cause then? Notes that the "warming" has not resulted in a corresponding expansion on the northern frontier claiming seeds don't travel far😒. Can't say it's a very well done piece
