Local Environmental Conditions
This area, about 300-400 meters off, has the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. Mown grass and ornamental trees in a nearby park, adding to seasonal grass and ragweed pollen, at around 400-500m distant. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Near the bank, hazel and willow lead the seasonal calendar, hitting its peak before most trees have even budded, around late winter into March. Moving into early summer, grass pollen climbs to its seasonal high in June, and then ragweed picks up the slack, running from mid-August through October. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

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. |
