Local Environmental Conditions
A waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species; this sits as close as 100-200m from this location. Nearby, a moderate 400-500 meters from here, a stretch of mown parkland where turf and ornamental trees feed local grass and ragweed pollen. Local wind exposure and land use can shift the exact mix slightly from block to block.
Hazel and willow near the water open the pollen calendar early, arriving ahead of the rest of the season, cresting around late winter. Grass pollen becomes the dominant allergen through late spring, peaking in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

Does pollen in Sixteen Mile Stand 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 Sixteen Mile Stand 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 Sixteen Mile Stand, 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. |
