Lodgepole pine (Pinus contorta Dougl.) covers extensive areas of the mountains of western North America. It has evolved into four subspecies, each adapted to slightly different environmental conditions. All are adapted to reproduce following fire. Subspecies latifolia is the most extensive and economically important in North America. Serotiny is common in this subspecies, but trees bearing nonserotinous cones can be found in most stands, sometimes constituting more that 70% of the trees. Cone crops are produced yearly and seed loss to seed predators, insects and diseases are minimal. Germination and establishment occurs across a broad range of conditions allowing lodgepole pine to grow on poor sites as well as highly productive sites. These characteristics give lodgepole pine the ability to be highly invasive in new areas of suitable habitat.
