Within Labrador, this ecozone occupies the northernmost section.

The largest ecozone, the Boreal Shield, extends in a broad, U-shape from northern Saskatchewan to Newfoundland.

This ecoregion is composed of islands, exposed headlands, and protected inlets, from Napaktok Bay south to the Strait of Belle Isle.

One very important feature of Newfoundland and Labrador is that the geological boundary of North America lies offshore at the edge of the continental shelf.

The Eagle Plateau ecoregion comprises the Mealy Mountains and an area south of Lake Melville in southern Labrador.
