Local Environmental Conditions
As a working farm and orchard at the birthplace of the Arbor Day holiday, Arbor Day Farm draws on the same plant life found across Nebraska City, keeping its pollen sources in step with the wider area. As with most sublevel sites, local landscaping can shift counts slightly from the citywide average.
Arbor Day Farm follows Nebraska City's established pollen calendar, beginning with elm and cottonwood from March with ash following close behind through April. Grass pollen builds through May and June, and a strong ragweed peak follows in late summer into September. Surrounding farmland is a major contributor to both the spring grass peak and the late-summer ragweed season, consistent with the wider Nebraska City area.

Does pollen in Nebraska City 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 Nebraska City 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 Nebraska City, 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. |
