Local Environmental Conditions
Here, near this part of town, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen. Located within the local area, this area has oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. 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, reaching its high point sometime in late winter or early spring. Oak and birch in the nearby woodland follow in mid-to-late spring, typically landing in April and May. Grass pollen builds through late spring and peaks in June, handing off to ragweed, which peaks from mid-August through October.

Does pollen in Thompson Township come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Thompson Township based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Thompson Township, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

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. |
