Persicaria

• Mostly iNaturalist : photos taken by people all over Québec, with the species confirmed by the community.
• Other public sources : such as eBird for birds and the provincial forest inventories, gathered by GBIF, the global biodiversity data network.
• What we keep : confirmed observations, with an exact position (not blurred to protect a rare species), that their author allows to be reused.
• One place counts once : several observations of the same species at the same spot (within 11 m) count as one.
• So our numbers are lower : than iNaturalist’s total. A region without observations does not mean the species does not live there.
