Around Herne, linden, oak, and maple stand out as the leading tree pollen sources in parks and gardens, with exposure shifting between green space and centre. Ruhr-area farmland and reclaimed colliery woodland on the town's outskirts add to local tree and grass pollen, while former industrial land now supports modest urban greenery.

Does pollen in Herne 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 Herne 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 Herne, 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.
