Floristic habitat is a protected area that houses at least one species listed as threatened or vulnerable and identified in section 7 of the Threatened or Vulnerable Floristic Species and Habitats Regulations. To date, 52 floristic habitats have been created. They are mainly located on land within the state domain and some are in private land. As stated in section 17 of the Threatened or Vulnerable Species Act, any activities that may alter the biophysical characteristics of these habitats are prohibited. Following the September 13, 2013 update of the Protected Areas Registry, floristic habitats encumbered in whole or in part with mineral, gas or oil rights were removed from the Registry to comply with the International Union for Conservation of Nature (IUCN) criteria for protected areas. As a result, only 31 floristic habitats remain on the Registry and can be accessed in the protected area layer. To view all floristic habitats, including the 21 habitats that are not registered in the Protected Areas Registry, consult the Floristic Habitats layer. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This thematic layer represents the characterization of the hardness of Québec's surface waters for the period 2005 to 2019. Hardness is presented according to the medians calculated from calcium and magnesium ions concentrations in seven classes. Water hardness influences the toxicity of certain metals, including barium, beryllium, cadmium, chromium, copper, manganese, nickel, lead and zinc. Surface water quality criteria are determined according to the hardness of the receiving watercourse. These criteria are used to judge the quality of surface water and are the basis of groundwater criteria used to assess the quality of groundwater that resurrects to surface water. Finally, they are the key element in the calculation of Environmental Discharge Objectives (EROs) used to assess the quality of wastewater releases to the aquatic environment. For an annual release, the median hardness of the receiving water body is generally used to calculate water quality criteria for aquatic life. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**
