Description
A forested community, this site occurs across the landscape as a mosaic of plant community phases characterized by variation in forest structural stage (tree age, density and cover) and plant community. Historically, many dry lodgepole pine forests would have cycled from a dense stand initiation phase (1.1) to a young forest stage (1.2) to a mature forest phase (1.3). These pathways are defined by a disturbance regime characterized by self-thinning and disease and insect outbreaks which allows the canopy to open over time and mature lodgepole pine to develop in the overstory. The Reference Native Plant Community under this natural disturbance regime is represented by Community 1.3.
Submodel
Mechanism
Extensive timber harvest followed by management prioritizing timber production.
Mechanism
Selective thinning, prescribed burning or shelter-wood production systems may increase chances of forest restoration. Stand replacing fire may return to a reference state if soil compaction is not severe and seed source is available.
Context dependence
Soil compaction and surface disturbances due to large machine usage may hinder passive forest reestablishment.
