Local Environmental Conditions
Moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind; this sits nearby. This area, within the neighborhood, has a canopy of oak and birch, birch chief among them for allergenic potency here. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
The bank's hazel and willow kick off the pollen season ahead of the rest, peaking in late winter through March. Woodland oak and birch pick up the pace next, through mid-to-late spring, reaching its high point through April and into May. Grass pollen builds through late spring and peaks in June, followed by ragweed's own peak stretch from mid-August into October.

Does pollen in Hickory Hill Campground 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 Hickory Hill 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 Hickory Hill 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. |
