Local Environmental Conditions
For Damon Pond Campground, the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze, not far from here. Here, not far from here, woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. As with most local readings, actual levels can vary somewhat with short-term weather swings.
In Damon Pond Campground, the woodland's oak and birch trees become the main pollen source by mid-spring, generally peaking somewhere between April and May. The water-adjacent hazel and willow are early risers, peaking in late winter through March. Grass pollen takes over next, building to a peak around June, followed by ragweed's own peak stretch from mid-August into October.

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