Local Environmental Conditions
For Riverwoods, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen, close to home here. Here, within the local area, woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. The general pattern described here holds fairly steady across nearby areas with similar land cover.
At Riverwoods, along the waterway, hazel and willow release pollen first, peaking in late winter through March. Oak and birch in the nearby woodland follow in mid-to-late spring, cresting around April and May in the year's sharpest tree-pollen spike. Grass pollen becomes the dominant allergen through late spring, peaking in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

Pollen
| None | 0 | No or negligible risk of exposure. Pollen exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
