Pinus contorta is fire successional over most of its range and is characterized by prolific seeding and high seed viability in disturbed habitats, often resulting in extremely slow-growing, overly dense stands. Some authors consider it to consist of 4 races; these have been given various infraspecific ranks, but perhaps they are more conventionally treated as 3 varieties.
