Habitat Class Modifiers
| Symbol | Phase | |
| c | coarse-textured soils | |
| g | gently sloping (alpine only) | |
| f | fine-textured soils | |
| l | shallow (lithic) soils | |
| m | moist soils | |
| n | cool (northerly) aspect (west northwest to southeast) | |
| s | steep, warm (southerly) aspect (southeast to west) | |
| t | moderate sloped, warm (southerly) aspect (southeast to west) | |
| u | upper elevation, gentle slope (forested areas) |
Successional Stages
| Symbol | Stage |
| 0 | non-forested units (alpine, wetlands) |
| 1 | recent disturbance (fire, logging) |
| 2 | young forests, coniferous (< 60 years) |
| 3 | young forests, broad-leaved or mixed (< 60 years) |
| 4 | mature forests, coniferous (60 to 140 years) |
| 5 | mature forests, broad-leaved or mixed (60 to 140 years) |
| 6 | old-growth ( > 140 years) |
