Dordrecht's island setting at the Merwede and Noord river confluence features oak, birch, and linden as the main tree pollen sources in green spaces along the waterways, with exposure varying between riverside areas and the more built-up city centre. Surrounding South Holland farmland and the Biesbosch wetlands contribute substantial grass and reed pollen across the river delta city.

Does pollen in Dordrecht 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 Dordrecht 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 Dordrecht, 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.
