The Parks / Northwest Territories / Tuktut Nogait National Park

Between 50 - 70% of Tuktut Nogait is dry treeless tundra, rocky barrens characterized by the presence of permafrost, short summers of 24-hour daylight, long dark winters and low annual precipitation. Tundra plants include lichens, mosses, grasses and low shrubs. Unlike other deer, the caribou is able to digest lichens as well as other available vegetation. Some species of wildflowers include mountain aven, the first spring flower, dryas, white mountain heather, moss campion, arctic poppy, the edible river beauty, and dense carpets of arctic willow and dwarf birch. Along the river valleys some stunted spruce trees mark the most northerly limit of any tree growth.
