Local Environmental Conditions
This area, within the neighborhood's edge, has hazel and willow thrive along the damp bank, both prolific early wind-pollinators. Neighboring areas with similar land cover tend to show a closely matching pollen mix. Year-to-year swings in rainfall and wind can shift this picture somewhat either way. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
The bank's hazel and willow kick off the pollen season ahead of the rest, hitting its peak before most trees have even budded, around late winter into March. Grass pollen becomes the dominant allergen through late spring, peaking in June, and then ragweed picks up the slack, running from mid-August through October.

Does pollen in Windsor 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 Windsor 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 Windsor 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
