Davis's flat Sacramento Valley agricultural setting features oak, olive, and native grasses as the main pollen sources, with exposure varying between the extensively tree-planted university campus and the more open surrounding farmland. The UC Davis campus arboretum contributes locally significant tree pollen diversity, while the surrounding Central Valley agricultural landscape dominates pollen exposure across the flat, open city throughout the season.

Does pollen in Davis 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 Davis 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 Davis, 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.
