Here, just outside the immediate area, the waterway's edge supports river oak, a species whose fine pollen travels well beyond the immediate bank. Here, in the wider area, eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load. Here, within the local area, a park whose lawns and ornamental plane trees quietly add to local pollen levels.

Does pollen in Glen Forrest 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 Glen Forrest 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 Glen Forrest, 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.
