Local Environmental Conditions
Hazel and willow cluster near the water, an early and reliable source of allergenic pollen; this sits positioned about 300-400m from the neighborhood. Nearby, conveniently close, some 600-700 meters off, oak and birch trees, with birch pollen especially potent during its brief spring window. Seasonal timing here generally tracks the wider region, give or take a week or so.
Near the bank, hazel and willow lead the seasonal calendar, hitting its peak before most trees have even budded, around late winter into March. Once hazel fades, oak and birch in the woods carry the season forward, reaching maximum intensity across the April-May window. Grass pollen climbs toward a June peak, before ragweed pollen takes center stage across mid-August into October.

Does pollen in Sylvania 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 Sylvania 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 Sylvania 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. |
