Critical habitat polygons and lines were assembled by SARA regional biologists and recovery teams. They are designed to support the protection and recovery of species listed as Endangered or Threatened under the Species at Risk Act. They are also described and displayed in species’ Recovery Documents and Action Plans. For the complete extent and view of a species' Critical Habitat both Lines and Polygons must be displayed simultaneously. Please note: there are different types of Critical Habitat descriptors. This dataset may use a “bounding box” or "parcel" approach that delineates an area or extent in which the species may be found. Descriptors (such as bounding box coordinates are not included in this dataset).
