Local Environmental Conditions
This area, just outside the immediate area, has hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Here, within easy reach, parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen. Small shifts in elevation or soil type can move these figures a little either way.
The bank's hazel and willow kick off the pollen season ahead of the rest, reaching its high point sometime in late winter or early spring. Grass pollen takes over next, building to a peak around June, and ragweed later takes the lead from mid-August through October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

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 Rostraver 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. |
