Local Environmental Conditions
The heart of Middle Brother is surrounded mainly by woodland, which covers around 100% of the nearby area. Close to running water, riverside vegetation contributes to what is in the air. The surrounding woodland makes trees an important local pollen source. Beyond the trees, grasses matter a great deal, and plantain is the main weed source.
Tree pollen comes first, peaking in early spring. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into early fall. Plantain flowers through much of the warmer half of the year. Warm, damp weather from midsummer into mid-fall also raises mold spore levels. Weather shapes each of these periods: dry, windy spells drive levels up, and showers wash pollen out of the air.

Does pollen in Middle Brother 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 Middle Brother 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 Middle Brother, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
