'''Wrangel Island''' is a mountainous [[island]] located well above the [[Arctic Circle]]. Wrangel was not glaciated during the Quaternary [[Ice Age]], resulting in exceptionally high levels of biodiversity for this region. The island boasts the world’s largest population of Pacific [[walrus]] and the highest density of ancestral [[polar bear]] dens. It is a major feeding ground for the [[grey whale]] migrating from [[Mexico]] and the northernmost nesting ground for 100 migratory [[bird]] species, many endangered. Currently, 417 species and subspecies of vascular plants have been identified on the island, double that of any other Arctic [[tundra]] territory of comparable size and more than any other [[Arctic]] island. Some species are derivative of widespread continental forms, others are the result of recent [[hybridization]], and 23 are [[endemic]].
