Local Environmental Conditions
Around 46% of the area near this site in Ypsilanti is woodland, with a good deal of built-up land and some open grassland. A watercourse nearby means riverside trees such as willow, poplar and plane tree are part of the local pollen picture. Oak and maple are among the allergenic trees nearby. Grasses are a major source, with plantain and ragweed adding to the weed pollen load.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak and maple are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Plantain and ragweed bring a final peak from late spring into early fall. By late fall, pollen levels are low again.

Does pollen in Ypsilanti 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 Ypsilanti 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 Ypsilanti, 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.
