Local Environmental Conditions
Located just outside the immediate area, this area has hazel and willow take root along the waterway, both prolific contributors to early pollen counts. Nearby, just around the area, tree cover made up mostly of oak and birch, both significant spring allergen sources. Green space with maintained lawn and planted trees, both contributing to grass and ragweed counts; this sits near this part of town.
Hazel and willow near the water open the pollen calendar early, arriving ahead of the rest of the season, cresting around late winter. The woodland's oak and birch trees become the main pollen source by mid-spring, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen becomes the dominant allergen through late spring, peaking in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Harborcreek 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 Harborcreek 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. |
