Bend's parks, including Drake Park and the Deschutes River corridor, feature pine, juniper, and cottonwood as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding high desert and the Cascade Mountain foothills contribute substantial pine, juniper, and grass pollen, while the semi-arid setting and open landscape allow pollen to disperse widely across the city under prevailing westerly winds.

Does pollen in Bend 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 Bend 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 Bend, 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.
