This ecoregion covers the Borden Peninsula of north-central Baffin Island and the southwestern coast of Bylot Island along Navy Board Inlet. The mean annual temperature is approximately -13°C with a summer mean of 1°C and a winter mean of -25°C. The mean annual precipitation ranges from 100 mm to over 200 mm with the higher values falling in the centre of the peninsula. This ecoregion is classified as having a high arctic ecoclimate. It supports a very sparse vegetative cover of moss and mixed low-growing herbs and shrubs such as purple saxifrage, Dryas spp., arctic willow, kobresia, sedge, and arctic poppy. The inland plateau, formed on flat-lying Palaeozoic and late Proterozoic carbonate rocks, slopes gently southward, ranging from about 765 to 300 m asl. Regosolic Turbic Cryosols with Regosolic Static Cryosols are dominant soils that have developed on a variety of undulating glacial deposits. Permafrost is deep and continuous with medium ice content. Characteristic wildlife includes caribou, muskox, polar bear, ptarmigan, arctic fox, seabirds, walrus, seal, and whale. Land uses include trapping, hunting, fishing, and tourism. Other activities include the Nanisivik lead, zinc and silver mine. The main settlements are Nanisivik, Pond Inlet, and Arctic Bay. The population of the ecoregion is approximately 1800.

This ecoregion is part of the Northern Arctic ecozone.
