Local Environmental Conditions
Moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind, just around the area. This area, within the local area, has oak and birch trees, with birch pollen especially potent during its brief spring window. Located within easy reach, this area has well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen.
Near the bank, hazel and willow lead the seasonal calendar, leading off the pollen calendar, with a peak generally falling in late winter. Once hazel fades, oak and birch in the woods carry the season forward, typically the year's sharpest tree-pollen spell, centered on April and May. Through late spring, grass pollen climbs steadily toward its June peak, and then ragweed picks up the slack, running from mid-August through October.

Are pollen levels in Willowbrook Golf Club 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 Willowbrook Golf Club, 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. |
