Chino Hills's inland San Bernardino County hillside setting features chaparral, oak, and olive as the main tree pollen sources, with exposure varying considerably between the steep chaparral-covered hillsides and the more built-up valley floor. The surrounding chaparral and scrub oak slopes are particularly significant local sources, creating distinct pollen gradients between the elevated hillside and the denser development in the valley areas.

Does pollen in Chino Hills 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 Chino Hills 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 Chino Hills, 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.
