Local Environmental Conditions
Open grassland makes up around 37% of the area near North Branch Conservation Area (cyclists only), with a good deal of woodland and farmland. With a watercourse close by, riverside trees such as willow contribute to the local mix. Of the allergenic trees nearby, oak matters most, while willow also contributes. Grasses add a sizeable share of the local pollen.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak and willow are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, pollen levels are low again.

Are pollen levels in North Branch Conservation Area (cyclists only) 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 North Branch Conservation Area (cyclists only), 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
