Local Environmental Conditions
Hazel and willow crowd the water's edge, both classic sources of early allergenic pollen; this sits within easy reach. Nearby, a short distance from here, a wooded area built around oak and birch, both contributing heavily to the region's spring pollen totals. Located in the surrounding area, this area has this park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load.
The waterside hazel and willow are consistently first to release pollen each year, starting well before the main spring rush, topping out around March. Oak and birch nearby take over the pollen calendar through mid-spring, climbing steadily through spring to a peak in April or May. Grass pollen rises through late spring toward a June high point, with ragweed climbing to its own high point from mid-August through October.

Does pollen in Caseville 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 Caseville 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 Caseville, 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. |
