How to connect?

birch, beech, and oak supply most of the tree pollen across Fröndenberg's parks and gardens, with levels varying between green space and the town centre. Farmland across the Sauerland and ridge-top forest nearby contribute additional tree and grass pollen, while varied slope orientation gives noticeably different exposure across the town.

Does pollen in Fröndenberg 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 Fröndenberg 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 Fröndenberg, 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.
