Well-known Canadian montane national parks have undergone a length period of fire suppression activities, which
started in the early 20th century. This has resulted in old growth forest stands that are relatively homogeneous in
nature, often containing forests that have the same species, age, and structure. In recent years, mountain pine
beetle outbreaks have occurred, especially in Jasper National Park, resulting in the dramatic transformation of
lodgepole pine forests surrounding the town site.
