This ecoregion occupies the north half of Prince of Wales Island and has 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 mean annual temperature is approximately -15.5°C with a summer mean of 1°C and a winter mean of -30.5°C. The mean annual precipitation ranges 100-150 mm. This ecoregion is classified as having a high arctic ecoclimate. The terrain of this lowland slopes gently to the southwest and is composed of stratified Palaeozoic carbonate rocks. Extensive areas of drumlinoid ridges impart a characteristic grain to the minor topography on the island. Turbic Cryosols are the dominant soils, and have developed on a variety of smooth, undulating glacial deposits. Continuous permafrost with a high ice content and abundant ice wedges are characteristic. Wildlife includes muskox, caribou, arctic hare, arctic fox, snowy owl, other raptors, polar bear, seal, whale, seabirds, and waterfowl.
This ecoregion is part of the Northern Arctic ecozone.
