Local Environmental Conditions
Tippecanoe Battlefield, a wooded historic battlefield park, shares its vegetation profile with the broader Lafayette area, so pollen exposure here tracks the same regional sources found across the city. As with most sublevel sites, local landscaping can shift counts slightly from the citywide average.
Tippecanoe Battlefield tracks Lafayette's broader pollen pattern, with maple and elm appearing from March with oak taking the lead through April. Peak grass pollen arrives in May and June, and ragweed pollen builds steadily from August into September. The continental Midwest climate produces a well-defined spring tree peak followed by a strong late-summer ragweed season, a defining feature of the local season.

Does pollen in Tippecanoe Battlefield 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 Tippecanoe Battlefield 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 Tippecanoe Battlefield, 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. |
