Local Environmental Conditions
The riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze, within the neighborhood. Nearby, close to this spot, birch and oak share the canopy here, birch pollen in particular known to travel far on the wind. Ground-level conditions like local landscaping can nudge these figures slightly either way.
Hazel and willow near the water open the pollen calendar early, hitting its peak before most trees have even budded, around late winter into March. Oak and birch in the nearby woodland follow in mid-to-late spring, reaching its high point through April and into May. Moving into early summer, grass pollen climbs to its seasonal high in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

Are pollen levels in Seneca Lake Park Campground 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 Seneca Lake Park Campground, 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. |
