Local Environmental Conditions
Here, within the neighborhood's edge, hazel and willow take root along the waterway, both prolific contributors to early pollen counts. Small shifts in elevation or soil type can move these figures a little either way. Neighboring areas with similar land cover tend to show a closely matching pollen mix. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
The bank's hazel and willow kick off the pollen season ahead of the rest, building through the tail end of winter into March. Through late spring, grass pollen climbs steadily toward its June peak, then yields to ragweed, the dominant late-summer and fall allergen through October. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

Does pollen in Greenwood 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 Greenwood 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 Greenwood 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. |
