Local Environmental Conditions
Nearby, in the wider area, water here is bordered by hazel and willow, both notable sources of wind-borne pollen. Here, close to home here, oak and birch dominating the treeline, both heavy contributors to the spring pollen load. Located not far from here, this area has a green space of mown lawn and planted trees, both feeding into local grass and ragweed counts.
Near the bank, hazel and willow lead the seasonal calendar, building through the tail end of winter into March. By mid-spring, oak and birch in the woods take over, topping out in the April-to-May stretch. By late spring, grass pollen is climbing steadily toward a June high point, and ragweed later takes the lead from mid-August through October.

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 North Attleborough, 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. |
