Local Environmental Conditions
Nearby, nearby, hazel and willow thrive along the damp bank, both prolific early wind-pollinators. This area, nearby, has oak and birch dominating the treeline, both heavy contributors to the spring pollen load. The general pattern described here holds fairly steady across nearby areas with similar land cover. Local wind exposure and land use can shift the exact mix slightly from block to block.
The waterside hazel and willow are consistently first to release pollen each year, climbing steadily from late winter into March. Woodland oak and birch pick up the pace next, through mid-to-late spring, topping out in the April-to-May stretch. Moving into early summer, grass pollen climbs to its seasonal high in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

Are pollen levels in West Pikeland 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 West Pikeland 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. |
