Species driving Coulter’s tree pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: tree pollen reads 0.6 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

Trees run from March into May, later near the big lakes. This month sits outside the usual tree pollen window for the Midwest & Great Lakes pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Iowa allergy season guide singles out ragweed, the state’s dominant allergen, over a maple, oak and hickory spring.
