Local Environmental Conditions
Around Camp Ammon, hazel and willow take root along the waterway, both prolific contributors to early pollen counts; this sits in the vicinity. Nearby, not far from here, a wooded area built around oak and birch, both contributing heavily to the region's spring pollen totals. This area, a short distance from here, has parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen.
At Camp Ammon, oak and birch in the woods pick up where the earlier species leave off, usually peaking from April into May. Grass pollen takes over next, building to a peak around June, with ragweed climbing to its own high point from mid-August through October. This general pattern holds fairly steady across the surrounding county from year to year.

Does pollen in West Allis 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 West Allis 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 West Allis, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
