Local Environmental Conditions
South Lynn — A stretch of hazel and willow lines the water, feeding some of spring's earliest pollen; this sits about 499 meters off. Oak and birch trees, with birch pollen especially potent during its brief spring window, practically next door, 209 meters off. Located not far off, about 347m out, this area has parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen.
Near the bank, hazel and willow lead the seasonal calendar, hitting its peak before most trees have even budded, around late winter into March. The area's oak and birch trees pollinate through mid-to-late spring, reaching its high point through April and into May. Grass pollen rises through late spring toward a June high point, before ragweed becomes the more dominant allergen from mid-August into October.

Does pollen in Evergreen Park 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 Evergreen Park 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 Evergreen Park, 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. |
