Local Environmental Conditions
Located within the local area, this area has a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. The tree cover here leans heavily on oak and birch, both key drivers of spring pollen, not far from here. Seasonal timing here generally tracks the wider region, give or take a week or so.
Along the waterway, hazel and willow release pollen first, building through the tail end of winter into March. Further into spring, the area's oak and birch stands drive the pollen count, topping out in the April-to-May stretch. Moving into early summer, grass pollen climbs to its seasonal high in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

Does pollen in Fairview 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 Fairview 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 Fairview 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. |
