The Lorillard herd is one of the tundra-wintering herds of Barren-ground caribou. As the name implies, unlike some other herds, these caribou do not go down to the treeline in winter. Its range is entirely in Nunavut, with the core of its range stretching northward from Chesterfield Inlet on the Hudson Bay coast and westward toward Baker Lake. Rankin Inlet and Naujaat are also within the herd’s range. Its range overlaps with the Qamanirjuaq, Ahiak and Wager Bay herds. The herd has not been surveyed since 2003. There is no current population estimate.
