Habitat
The Rocky Mountain spruce is found in high elevation forests of western North America, often immediately below tree line. The tree is very shade tolerant and the branches are built to collect snow to protect the tree from wind and heat.

Fun Fact

  • The Rocky Mountain Fir can reproduce by “layering”, a process where tree branches that touch the ground form roots and then create new trees. This can lead to an incredible natural phenomena where a ring of trees is created in the wild.
