Local Environmental Conditions
The nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees; this sits close by. Here, just around the area, woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. Small shifts in elevation or soil type can move these figures a little either way.
Hazel and willow along the water get the season underway before other species, climbing steadily from late winter into March. As spring advances, oak and birch in the nearby woodland become the dominant source, reaching its high point through April and into May. Grass pollen counts rise through late spring, reaching their peak around June, with ragweed climbing to its own high point from mid-August through October.

Does pollen in Dysart et al 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 Dysart et al 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 Dysart et al, 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. |
