Notes
Western white pine is susceptible to white pine blister rust, which causes portions of the tree to turn an orangey-brown colour and die. The rust is difficult to control and prevents the tree from being of commercial importance.

The botanist David Douglas first identified western white pine on the slopes of Mount St. Helens. It gets its common name from the light colour of the wood. The Latin name monticola means "inhabiting mountains."
