Local Environmental Conditions
Rogers's Northwest Arkansas Ozark setting features oak, cedar, and hickory as the main tree pollen sources, with exposure varying between the wooded Ozark plateau residential areas and the more built-up commercial corridors along Walnut Street. Beaver Lake to the east provides temperature-modifying effects, while the Ozark highland topography creates distinct pollen gradients between the ridge tops and the valley communities throughout the season.
Rogers's Northwest Arkansas Ozark setting produces a season opening in late January with cedar and elm before oak peaks through March and April. Grass from surrounding Arkansas Ozark farmland peaks through May and June before mugwort and nettle extend exposure into September. The cedar season from December through February is a locally significant source, while the Ozark setting concentrates pollen in certain valley locations.

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. |
