Local Environmental Conditions
The waterway's edge supports hazel and willow, species known for potent, wind-carried pollen; this sits a short trip out, around 500-600m. This area, some 300 meters out, has oak and birch trees, with birch pollen especially potent during its brief spring window. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
Hazel and willow by the water are typically first out of the gate, usually the first pollen source active, peaking sometime in February or March. Woodland oak and birch pick up the pace next, through mid-to-late spring, typically the year's sharpest tree-pollen spell, centered on April and May. Late spring brings rising grass pollen that crests in June, handing off to ragweed, which peaks from mid-August 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. |
