Local Environmental Conditions
At Proposed Campground Expansion, nearby, within the local area, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. Located close to home here, this area has a park combining lawn grass and planted trees, both minor but real contributors to pollen here. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
In Proposed Campground Expansion, along the waterway, hazel and willow release pollen first, topping out well before most other trees start releasing pollen, around February and March. Late spring sees grass pollen build steadily toward a peak in June, before ragweed pollen takes center stage across mid-August into October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

How often is the Proposed Campground Expansion pollen forecast updated?

Does pollen in Proposed Campground Expansion 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 Proposed Campground Expansion 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 Proposed Campground Expansion, 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. |
