Hanover Park lies in the DuPage River watershed, not far from Salt Creek and Herrick Lake Forest Preserve. The surrounding landscape is dominated by floodplain forest and remnant black-soil prairie. Salt Creek winds through the wider area, its banks favoring moisture-loving trees such as willow and alder. Local vegetation still varies with soil type and drainage.

Does pollen in Hanover Park 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 Hanover Park 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 Hanover Park, 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.
