Local Environmental Conditions
Here, near this part of town, moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind. Nearby, just around the area, a stand of oak and birch, the latter ranked among the region's most potent tree allergens. Local microclimate and soil conditions can push these figures slightly higher or lower.
The water-adjacent hazel and willow are early risers, usually peaking sometime between late winter and the end of March. The nearby oak and birch stands take the lead as spring progresses, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen takes over next, building to a peak around June, before ragweed becomes the more dominant allergen from mid-August into October.

Does pollen in Frost 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 Frost 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 Frost 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. |
