Overall Overview
Total pollen declined by 38, driven entirely by lower tree pollen. Total mold decreased by 951, with broad-based declines across most major mold groups.
Tree, Grass, and Weed Pollen
- Tree pollen fell by 38, almost entirely due to Cedar (-34) and Elm (-4).
- No other tree species showed activity.
- Grass pollen remained at zero.
- Weed pollen remained at zero across all species.
Mold Spores
- The largest contributors to the mold decline were Ascomycetes (-300) and Cladosporium (-300).
- Additional meaningful decreases came from Smuts/Myxomycete (-150) and Basidiomycetes (-97).
- Smaller but notable declines were observed in Epicoccum (-20), Algae (-16), Alternaria (-16), and several species dropping to zero.
- Only minor increases were seen in Spegazinia (+2) and Tetraploa (+2), which had no material impact on the total.
Key Takeaways
- Tree pollen dropped sharply, led by a pullback in Cedar.
- Grass and weed pollen remained inactive.
- Mold levels fell substantially, with declines spread across multiple dominant mold categories rather than driven by a single species.
