Local Environmental Conditions
In RV Back-in Sites, here, close by, a waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species. This area, not far from here, has this park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load. The broader area tends to mirror this pattern, with only minor local variation.
In RV Back-in Sites, the water-adjacent hazel and willow are early risers, topping out well before most other trees start releasing pollen, around February and March. Grass pollen builds through late spring and peaks in June, and ragweed later takes the lead from mid-August through October. Regional pollen monitoring generally reflects this same pattern across nearby areas.

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 Le Ray 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 Le Ray 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. |
