Local Environmental Conditions
Water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen, close to home here. Here, not far from here, a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
For Yarragil Campground, the waterside river oak is consistently first to release pollen each year, reaching its high point sometime in late winter or early spring. Eucalypt and wattle in the woods pick up where river oak leaves off, topping out in the August-to-September stretch. Through spring, grass pollen climbs steadily toward its November peak, then holding at a high level well into January before easing off.

Does pollen in Nanga Brook 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 Nanga Brook 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 Nanga Brook, 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. |
