Local Environmental Conditions
Here, nearby, the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load, in the wider area. Located within the local area, this area has a stretch of mown parkland where turf and ornamental trees feed local grass and ragweed pollen.
The bank's hazel and willow kick off the pollen season ahead of the rest, leading off the pollen calendar, with a peak generally falling in late winter. Oak and birch in the nearby woodland follow in mid-to-late spring, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed's late-summer surge carries the season 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. |
