Local Environmental Conditions
Nearby, practically next door, 150 meters off, hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two, a stone's throw away, around 100m. Nearby, within easy reach at 350m, this park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load.
The water-adjacent hazel and willow are early risers, climbing steadily from late winter into March. 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. Moving into early summer, grass pollen climbs to its seasonal high in June, with ragweed climbing to its own high point from mid-August through October.

Does pollen in East Lansing 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 East Lansing 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 East Lansing, 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. |
