Local Environmental Conditions
Nearby, within easy reach, water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. A canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here; this sits not far from here. Local readings for the surrounding area tend to follow this same general pattern.
Near the bank, river oak leads the seasonal calendar, peaking in mid-winter through September. Woodland eucalypt and wattle pick up the pace next, through late winter into spring, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen becomes the dominant allergen through spring, peaking in November, with the season extending well into summer before finally winding down in February.

Does pollen in Main Ridge 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 Main Ridge 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 Main Ridge, 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. |
