Local Environmental Conditions
This area, within the local area, has hazel and willow take root along the waterway, both prolific contributors to early pollen counts. Nearby, not far from here, oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
Water-edge hazel and willow are usually the first allergenic trees active here, hitting its peak before most trees have even budded, around late winter into March. The area's oak and birch trees pollinate through mid-to-late spring, topping out in the April-to-May stretch. Grass pollen builds through late spring and peaks in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
