Produced as part of the St. Lawrence Action Plan, the Atlas of Territories of Conservation Interest in the St. Lawrence Lowlands presents the sites where conservation needs are the most urgent. The conservation targets selected (coarser filter) are forest environments, wetlands, open areas (wastelands, perennial crops) and aquatic environments to which are added fine filter elements such as exceptional aquatic environments associated with the St. Lawrence corridor (e.g. spawning grounds), alvars, bird colonies, faunal elements (e.g. breeding sites of Shore Swallow and Chimney Swallow, etc.) and important floristic occurrences. Our objective is to determine the sites of interest until a representative threshold of 20% is reached. The geospatial data associated with sites of conservation interest, the user guide, the methodological report, the metadata, as well as the detailed cartography of land use in the St. Lawrence Lowlands, which was essential basic data for producing this atlas, are available for download. Users can therefore more accurately consult the spatial distribution of sites of interest and the conservation value associated with each habitat parcel of conservation targets (forest environments, wetlands, wastelands, perennial crops, aquatic environments) using geographic information systems (e.g. ArcGIS). Users can also adapt the analysis of these data to their territorial reality and according to specific objectives specific to their interests. Since the conservation of natural environments and species in precarious situations is a shared responsibility, this Atlas will make it possible to meet the priorities of the numerous organizations involved in the conservation of natural environments in the St. Lawrence Lowlands.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
