Local Environmental Conditions
Located nearby, this area has the nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load; this sits near this part of town. Located close to this spot, this area has a green space where lawn grass and ornamental plantings top up the local grass and ragweed count.
The bank's hazel and willow kick off the pollen season ahead of the rest, reaching its high point sometime in late winter or early spring. As spring advances, oak and birch in the nearby woodland become the dominant source, building to its sharpest point across April and May. Late spring brings rising grass pollen that crests in June, with ragweed then rising to the fore from mid-August through October.

Does pollen in Algoma Township come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Algoma Township based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Algoma Township, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
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. |
