Local Environmental Conditions
Here, within an easy 50m reach, hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Located at a workable 700m distance, this area has forest where oak and birch make up much of the canopy, driving spring pollen counts. A park whose lawns and ornamental trees quietly add to grass and ragweed pollen levels, about 300-400 meters off.
Hazel and willow near the water open the pollen calendar early, usually the first pollen source active, peaking sometime in February or March. By mid-spring, oak and birch in the woods take over, usually peaking from April into May. Grass pollen rises through late spring toward a June high point, before ragweed pollen takes center stage across mid-August into October.

Does pollen in Danbury 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 Danbury 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 Danbury 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. |
