HRB Values >120% generally make it easier for fires to be contained.
- HRB = >30% to 50%: Mostly to completely cured, treat as dead fuels.
- HRB = >50% to 80%: Significant yellowing and curing. Live fuels contributing to spread.
- HRB = >80% to 100%: Green color pales. Grasses become less resistant to spread.
- HRB = >100% to 120%: Mature foliage, new growth complete, and comparable to older perennial foliage. Flammable shrubs should burn. Grasses resist spread.
- HRB = >120% to 150%: Mature foliage, new growth complete, and comparable to older perennial foliage. Shrubs and grasses resist spread.
- HRB = >150% to 300%: Maturing foliage still developing. Fresh foliage fully expanded, vigorously growing. Early in growing cycle.

- KBDI = 0 - 200: Soil moisture and large class fuel moistures are high and do not contribute much to fire intensity. Typical of spring dormant season following winter precipitation.
- KBDI = 200 - 400: Typical of late spring, early growing season. Lower litter and duff layers are drying and beginning to contribute to fire intensity.
- KBDI = 400 - 600: Typical of late summer, early fall. Lower litter and duff layers actively contribute to fire intensity and will burn actively.
- KBDI = 600 - 800: Often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.
