Local Environmental Conditions
Here, within the neighborhood's edge, the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. This area, nearby, has a wooded stretch of oak and birch, with birch responsible for some of the sharpest spring counts. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Hazel and willow along the water get the season underway before other species, hitting its peak before most trees have even budded, around late winter into March. Woodland oak and birch pick up the pace next, through mid-to-late spring, reaching maximum intensity across the April-May window. 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 Harborcreek 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 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. |
