Local Environmental Conditions
Nearby, some 200-300 meters out, moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind. Located roughly 300-400 meters to the north or south of here, this area has a stand of oak and birch, the latter ranked among the region's most potent tree allergens.
Near the bank, hazel and willow lead the seasonal calendar, peaking in late winter through March. As spring advances, oak and birch in the nearby woodland become the dominant source, reaching its high point through April and into May. Grass pollen becomes the dominant allergen through late spring, peaking in June, with ragweed then rising to the fore from mid-August through October.

Does pollen in Dearborn 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 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, 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. |
