Local Environmental Conditions
Hazel and willow cluster near the water, an early and reliable source of allergenic pollen; this sits in the wider area. This area, within the local area, has a wooded area built around oak and birch, both contributing heavily to the region's spring pollen totals. Local microclimate and soil conditions can push these figures slightly higher or lower.
Near the bank, hazel and willow lead the seasonal calendar, climbing steadily from late winter into March. Oak and birch nearby take over the pollen calendar through mid-spring, cresting around April and May in the year's sharpest tree-pollen spike. By late spring, grass pollen is climbing steadily toward a June high point, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

Does pollen in Mentor 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 Mentor 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 Mentor 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. |
