Local Environmental Conditions
Located close by, this area has water here is bordered by hazel and willow, both notable sources of wind-borne pollen. Located nearby, this area has a wooded area built around oak and birch, both contributing heavily to the region's spring pollen totals. Nearby, just outside the immediate area, this park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load.
Near the bank, hazel and willow lead the seasonal calendar, arriving ahead of the rest of the season, cresting around late winter. As spring advances, oak and birch in the nearby woodland become the dominant source, generally peaking somewhere between April and May. Grass pollen climbs toward a June peak, followed by ragweed's own peak stretch from mid-August into October.

How often is the Ashland pollen forecast updated?
The Ashland pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Ashland 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 Ashland 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 Ashland, 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. |
