Here, within the neighborhood's edge, oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. The general pattern described here holds fairly steady across nearby areas with similar land cover.
The water-adjacent hazel and willow are early risers, building through the tail end of winter into March.

Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
