Copenhagen Dyrehaven (Deer Park) occupies the classic Danish royal deer forest north of Copenhagen, where beech, oak, and birch are the dominant pollen sources across this extensive ancient woodland and open deer pasture. The enclosed forest concentrates pollen under calm conditions, while birch peaks through April and May, grass from the open deer pastures peaks through June and July, and mugwort extends into September throughout this beloved Copenhagen northern royal hunting forest.

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.

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 Copenhagen, 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.
