Local Environmental Conditions
Along the damp banks, hazel and willow release some of the year's first tree pollen, a short distance from here. Nearby, close to this spot, woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. Nearby, nearby, the park's turf and planted trees form a small but steady source of grass and ragweed pollen.
Near the bank, hazel and willow lead the seasonal calendar, arriving ahead of the rest of the season, cresting around late winter. Further into spring, the area's oak and birch stands drive the pollen count, typically the year's sharpest tree-pollen spell, centered on April and May. As spring turns to summer, grass pollen rises toward its June high, 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. |
