Imperatriz commands the southwestern Maranhão on the Tocantins River at the Amazon-cerrado forest transition, where native cerrado trees, secondary Amazon forest, and babaçu palm are the main pollen sources. The wet season from October to April brings frequent rainfall interruptions, while the dry season concentrates pollen dispersal and the forest-cerrado transition contributes a distinctive mixed pollen environment throughout this important Maranhão-Pará border city.

Does pollen in Imperatriz 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 Imperatriz 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 Imperatriz, 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.
