Local Environmental Conditions
Ferson Creek Woods — Hazel and willow crowd the water's edge, both classic sources of early allergenic pollen; this sits close by, around 400 meters away. Forest where oak and birch make up much of the canopy, driving spring pollen counts; this sits right nearby, about 58m away. Here, a moderate 481 meters from here, a nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix.
Hazel and willow by the water are typically first out of the gate, building through the tail end of winter into March. Oak and birch in the woodland come next, through the heart of spring, building to its sharpest point across April and May. Grass pollen rises through late spring toward a June high point, before ragweed becomes the more dominant allergen from mid-August into October.

| 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. |
