Local Environmental Conditions
The vegetation around Selma, on the Alabama River bluffs in the Black Belt region, is dominated by southern live oak with Spanish moss and loblolly pine, with riverside cypress adding further seasonal pollen exposure. Individual yards and gardens around Selma can still vary somewhat from this general pattern. Nearby towns with similar terrain tend to see a broadly similar pattern.
Selma's tree pollen season begins with cedar and elm from February with oak taking the lead through March and April. Grass pollen builds through April and May, and mugwort and nettle extend exposure into September. Warm, humid conditions favor an early, intense tree pollen season across the region, shaping conditions across the city.

| 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. |
