Local Environmental Conditions
Nearby, within easy reach, hazel and willow thrive along the damp bank, both prolific early wind-pollinators. Nearby, a short distance from here, the tree cover here leans heavily on oak and birch, both key drivers of spring pollen. This park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load, within the local area.
Hazel and willow near the water open the pollen calendar early, arriving ahead of the rest of the season, cresting around late winter. By mid-spring, oak and birch in the woods take over, generally peaking somewhere between April and May. Late spring brings rising grass pollen that crests in June, before ragweed's late-summer surge carries the season into October.

Does pollen in Vernon Hills 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 Vernon Hills 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 Vernon Hills, 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. |
