Local Environmental Conditions
The landscape around this part of Jarrahdale is heavily wooded. With a stream or river close by, riverside vegetation contributes to the local mix. Trees are an important local pollen source, given how much woodland surrounds the area. Grasses and weeds such as pigweed round out the local mix. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in late spring and keep pollen in the air into early fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Jarrahdale 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 Jarrahdale 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 Jarrahdale, 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.

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. |
