Local Environmental Conditions
Here, in the surrounding area, the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. Here, not far from here, this patch of forest is largely oak and birch, a pairing known for heavy spring pollen output. Small shifts in elevation or soil type can move these figures a little either way.
The waterside hazel and willow are consistently first to release pollen each year, hitting its peak before most trees have even budded, around late winter into March. The area's oak and birch trees pollinate through mid-to-late spring, peaking in the heart of spring, generally April into May. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed's late-summer surge carries the season into October.

Are pollen levels in Neys Park - Campground Area #4 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 Neys Park - Campground Area #4, 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. |
