Local Environmental Conditions
Here, practically next door, 50 meters off, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen. Here, a short trip out, around 550m, parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen. The general pattern described here holds fairly steady across nearby areas with similar land cover.
Near the bank, hazel and willow lead the seasonal calendar, starting well before the main spring rush, topping out around March. Grass pollen counts rise through late spring, reaching their peak around June, with ragweed then rising to the fore from mid-August through October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

Does pollen in Norvell 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 Norvell 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 Norvell 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. |
