Local Environmental Conditions
Open grassland and woodland share the area around the heart of Marion Township, plus some farmland. Locally, the surrounding woods make trees an important source; open grassland and farmland add grass and weed pollen. Grasses along roadsides, verges and open ground also add to the overall pollen load. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Tree pollen comes first, peaking in mid-spring. Grass pollen follows, peaking in early summer and easing off by late summer. Weeds on open ground add a smaller late peak from early summer into early fall. By late fall, as temperatures fall to around freezing, pollen levels are low again. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

Does pollen in Marion 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 Marion 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 Marion 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
