Woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen, within the neighborhood. This area, within the neighborhood, has a stretch of mown parkland where turf and ornamental trees feed local grass and ragweed pollen.
At Alexander Ramsey Municipal Park, woodland oak and birch pick up the pace next, through mid-to-late spring, cresting around April and May in the year's sharpest tree-pollen spike. Along the waterway, hazel and willow release pollen first, climbing steadily from late winter into March. Grass pollen rises through late spring toward a June high point, before ragweed becomes the more dominant allergen from mid-August into October.

Does pollen in Redwood Falls 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 Redwood Falls 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 Redwood Falls, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
