The trees that are left is what evolved out of these pine forests (Ponderosa Pines would be a good example).

The pine forests were pushed a lot further down and where there is a lot of forest in the Yukon, British Columbia and Alberta, there was steppe. This is the biome of the American Horse, American Camel and the Woolly Mammoth. There are only token relics left of that old steppe biome left, and it is that disappearance that led to the extinction of the Woolly Mammoth and the sort.
