Description

The Reference State is more common on Steep Loamy-Mantled Ridges ecological site than it is on the more readily accessible Loamy-Mantled Uplands ecological sites. This is due mainly to the steeper slopes and smaller areas involved. However, an untouched Reference State is still a relatively rare occurrence.

Description

This state often closely resembles the reference state after the rotation age for the initial regrowth passed; many Steep Loamy-Mantled Ridges ecological sites are like this. Recently logged sites are a different story, of course. It takes longer for a closed canopy forest to regenerate on these steeper sites, along with the higher probability that multiple microsites found on this show different trajectories toward a mature forest. For example steep, upper backslope portions with a southerly aspect will be the driest part of the site and will be likely exhibit slowest regrowth with only drought-adapted species.

State 3
Disturbed/Invaded State

Previous Next

Description

This state is less common on the steeper sites than it is on lesser slopes. The edaphic conditions on the sites change rapidly over short distances.

State 4
Converted State

Description

Again, this state is of lesser extent than on sites with lower slope gradients. These sites are subject to erosion.
