Local Environmental Conditions
The heart of Evergreen is heavily wooded. A nearby park adds mown lawns and planted trees to the local pollen mix. Common allergenic trees nearby include juniper and poplar. Grass pollen is plentiful, while mugwort leads among the weeds. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Juniper and poplar lead the season in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Grasses take over in early summer and keep pollen in the air into early fall. Mugwort brings a final peak from midsummer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels.

How often is the Evergreen pollen forecast updated?

Does pollen in Evergreen 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 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, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
