Local Environmental Conditions
Dearborn Heights's Detroit suburban Michigan setting features oak, maple, and elm as the main tree pollen sources, with exposure varying between the limited greener residential areas and the more built-up commercial and industrial corridors along Cherry Hill Road. The Rouge River corridor provides locally significant green space, while the flat, densely developed suburban landscape means limited local vegetation variation and pollen is largely carried in from surrounding greener areas.
Dearborn Heights's Detroit suburban setting in Michigan produces a season opening in late March with elm and maple before oak peaks through May. Grass from surrounding Michigan farmland peaks through June and July before mugwort and nettle extend exposure into September. The Rouge River corridor channels airflows, while the Great Lakes continental climate produces a well-defined seasonal progression throughout this western Detroit suburban city.

Does pollen in Dearborn Heights 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 Dearborn Heights 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 Dearborn Heights, 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. |
