Local Environmental Conditions
This area, just outside the immediate area, has along the damp banks, hazel and willow release some of the year's first tree pollen. Here, close by, oak and birch dominating the treeline, both heavy contributors to the spring pollen load. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
Hazel and willow near the water open the pollen calendar early, topping out well before most other trees start releasing pollen, around February and March. Oak and birch nearby take over the pollen calendar through mid-spring, usually peaking from April into May. As spring turns to summer, grass pollen rises toward its June high, before ragweed pollen takes center stage across mid-August into 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. |
