Local Environmental Conditions
In Plum Creek Campground, nearby, within easy reach, the nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees. A wooded stretch of oak and birch, with birch responsible for some of the sharpest spring counts, not far from here. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
At Plum Creek Campground, hazel and willow along the water get the season underway before other species, usually peaking sometime between late winter and the end of March. Grass pollen becomes the dominant allergen through late spring, peaking in June, before ragweed pollen takes center stage across mid-August into October.

Does pollen in Plum Creek 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 Plum Creek 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 Plum Creek 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. |
