Description
The Reference State for this site has two phases: one for early successional, post-disturbance communities and another for later successional, edaphic climax communities. These phases represent endpoints on the successional continuum, but this site seems to have fewer naturally occurring intergrade phases on the continuum than other sites. The transition from early phase to late phase proceeds rapidly due in part to the short life span of quaking aspen and balsam fir compared to white pine and red maple.

Description
The Cutover State has largely replaced the Reference State. The Cutover Sate has two main phases; intergrade phases can occur depending on the how and when logging was conducted. Recent logging will regenerate to the Aspen-Bracken-Blueberry Phase and logging sites older than fifty years have enough time to produce a community that resembles the pre-logging condition minus some of the old-growth pine trees.

Description
The Disturbed/Invaded State is occurring with increasing frequency on this site. This state has two main phases, earthworm invaded and weed invaded. Earthworm invaded sites may or may not have invasive weeds but weed invaded sites are likely to have worms as well.
