This DRAFT report describes the methods and results of a calving ground survey of the Bluenose-East barren-ground caribou herd conducted June 3-15, 2025, west of Kugluktuk, Nunavut. It updates abundance estimates of the herd from the calving ground survey results and integrated population models.

This thesis investigates how environmental change focused on lake ice phenology and monitoring tools focused on GPS collars, influence caribou movement behaviour and, potentially, survival.

This report provides statistical commentary on survey methods used to monitor barren-ground caribou herds in the Northwest Territories (NWT) with an emphasis on intervals between surveys and survey precision.

This report describes the results of a fall composition survey of the Bluenose-East barren-ground caribou herd conducted in October 2021.

This report describes the results of a calving ground photo survey of the Bluenose-East barren-ground caribou herd conducted June 4-13, 2023 west of Kugluktuk in Nunavut. The survey was flown to develop updated estimates of numbers of breeding females, adult females, and herd size.

This is a GNWT commitment made during the WRRB's Science Technical Session on October 5, 2020 to update precision for the ungulate biomass index estimates found in the technical report.

These are GNWT commitments made during the WRRB's Science Technical Session on October 5, 2020 to: 1) provide a summary of stomach contents of all harvested wolves (ground and aerial); 2) conduct additional model runs using caribou centric model; 3) share information from aerial removal data forms, specifically information on the number of packs and the number of wolves in those packs; 4) identify on which herd’s winter range the collared wolves were captured (by individual wolf), and

This report describes the results of calving ground composition surveys of the Bathurst and Bluenose-East caribou herds conducted in June of 2019 near Bathurst Inlet and west of Kugluktuk in Nunavut (NU). The main purpose of the surveys was to estimate the proportion of breeding females (cows that gave birth as a proportion of all cows) which indicates the initial calf productivity on the two calving grounds. In addition, the surveys estimated the relative distribution of breeding caribou on each calving ground as well as relative abundance of predators.

The Bathurst herd’s winter range in some years overlaps the winter ranges of its neighboring herds (Bluenose East, and Beverly/Ahiak herds). The overlapping winter distribution between the herds has complicated monitoring, assigning harvests and possibly affects potential switches of cows between calving grounds.
