Local Environmental Conditions
This area, in the surrounding area, has a waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species. Green space with maintained lawn and planted trees, both contributing to grass and ragweed counts; this sits in the wider area. Local microclimate and soil conditions can push these figures slightly higher or lower.
Hazel and willow near the water open the pollen calendar early, getting an early start, typically cresting between February and March. Grass pollen climbs toward a June peak, with ragweed then rising to the fore from mid-August through October. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

Does pollen in Ephrata Township 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 Ephrata Township 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 Ephrata Township, 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. |
