The 2023 mapping of potential wetlands in Quebec (CMHPQ) 2023, released by the Directorate of Ecological Knowledge (DCE), provides up-to-date information on the potential presence of wetlands for the entire province of Quebec. In particular, version 2023 contains the classification of potentially humid geographical entities according to a selected typology and the assignment of a level of confidence associated with each entity and integrates new data sources. This mapping is an aggregation of different databases produced for other purposes and at different scales. The result of this assembly depends on the precision and accuracy of each of the data sources used. This data must be used while remaining vigilant with regard to their potential and limitations.This third party metadata element was translated using an automated translation tool (Amazon Translate).
