How to connect?

Oak, birch, and linden are the backbone of tree pollen in Heerenveen's parks and avenues, though levels vary noticeably between the dense centre and the leafier edges of town. the Friese meadows and Skoatterwald forest, alongside the Fryslân farmland around Heerenveen, brings extra grass and tree pollen into an area known as a meadow and forest-edge town.

Does pollen in Heerenveen 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 Heerenveen 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 Heerenveen, 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.
