ËÄ»¢Ó°Ôº Pollen Count

Updated: Monday, May 18, 2026

We are officially in the "birch plateau." While we haven't seen another massive jump in numbers, the air remains heavily saturated with Betula pollen. Meanwhile, the early-season dominance of poplar seems to be winding down significantly.

The total volume of pollen in the air is still very high, but the "flavor" of the air has changed. We have moved from a birch/poplar mix to a landscape almost entirely defined by birch and alder. If you're heading out to the trails this evening, keep the windows up—the birch "fog" isn't lifting just yet!

Birch - 924 - high

Poplar/cottonwood/aspen - 12 - low

Alder - 72 - moderate

Willow - 12 - 12

Tamarack - 5 - low
