Species driving Bilieu’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.

What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

Hazel and alder open from February, and birch leads the spring peak through April and into May. This month sits outside the usual tree pollen window for the Continental West pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No France allergy season guide is published yet, so the seasonal context here follows the Continental West regional pattern.
