Local Environmental Conditions
Here, within easy reach, hazel and willow take root along the waterway, both prolific contributors to early pollen counts. This area, within the local area, has oak and birch trees, with birch pollen especially potent during its brief spring window. Maintained parkland where turf grass and ornamental species add to the grass and ragweed mix, a short distance from here.
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. Oak and birch nearby take over the pollen calendar through mid-spring, reaching its high point through April and into May. Late spring sees grass pollen build steadily toward a peak in June, followed by ragweed's own peak stretch from mid-August into October.

Does pollen in Vanport Township come from nearby or far away?

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 Vanport 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 Vanport 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. |
