White Spruce
All the observations I have made about trees on my local streets have one thing in common: the bark being adapted to certain climates. Thick bark exists among trees that are from drier, temperate forests whereas smooth, thin bark is for high humidity in tropical rainforests. The thick bark helps limit moisture evaporation from the tree trunk whereas trees that did not need to adapt to drier climates have thin bark. One observation I focused on was the white spruce tree. It is has adapted to be cone shaped to allow snow to fall off of it to prevent an accumulation of snow that could collapse the tree.
