Local Environmental Conditions
Hazel and willow thrive along the damp bank, both prolific early wind-pollinators; this sits just over 100-200 meters from the neighborhood. This area, only about 50 meters off, has oak and birch dominating the treeline, both heavy contributors to the spring pollen load. Green space with maintained lawn and planted trees, both contributing to grass and ragweed counts, right nearby, about 50m away.
Near the bank, hazel and willow lead the seasonal calendar, usually the first pollen source active, peaking sometime in February or March. Once hazel fades, oak and birch in the woods carry the season forward, generally peaking somewhere between April and May. Grass pollen takes over next, building to a peak around June, and then ragweed picks up the slack, running from mid-August through October.

Does pollen in Kelleys Island 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 Kelleys Island 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 Kelleys Island, 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. |
