Local Environmental Conditions
River oak crowds the water's edge here, a well-known contributor to local casuarina pollen counts, just around the area. Located close by, this area has a canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here. The general pattern described here holds fairly steady across nearby areas with similar land cover.
Along the waterway, river oak releases pollen first, climbing steadily from mid-winter into September. The woodland's eucalypt and wattle trees become the main pollen source as wattle flowers, reaching maximum intensity across the August-September window. Grass pollen becomes the dominant allergen through spring, peaking in November, before gradually tapering off through the peak of summer into February.

Does pollen in Tarra Valley 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 Tarra Valley 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 Tarra Valley, 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. |
