1 Size of the home range (km2) was determined from a GIS assessment of the ranges identified in the Scientific Review.2 Condition of the home range (% disturbed) is the category and percentage disturbance of all ranges identified in the Scientific Review.3 The population and area of home ranges in Alberta includes the population and area of the herds that AB shares with NWT (2) and BC (1), which
inflates the total for population and area of home ranges for Alberta and reduces the population and area in British Columbia and the NorthwestTerritories.
4 Labrador is mainland portion of Newfoundland and Labrador and does not include the area of populations of caribou on the island ofNewfoundland.
