The Eastern Canadian Shield

World Wildlife Fund
(WWF) categorization system.

Setting

Located in northeastern Canada, this ecoregion covers a large part of northern Quebec and most of Labrador, reaching from Hudson Bay and James Bay in the west, across to Ungava Bay and east to the Atlantic Ocean coast of Labrador. This is a taiga ecoregion and therefore stops at the treeline, beyond which is tundra. This is a rugged rocky landscape including an area fjords on the Atlantic coast of Labrador. The hills and plateaus are dotted with many lakes and string bogs, and patches of tundra on the Mealy Mountains and elsewhere.

This is a cold part of the world with average annual temperatures ranging from −6°C in Hudson Bay to 1°C on the Labrador coast.[3]

Flora

The dominant trees of the taiga are black spruce (

dwarf birches, willows, laurels, and rhododendrons. The boglands are a habitat of sedges and sphagnum
moss.

Fauna

The ecoregion is home to wildlife including

Corvus corax) and many waterbirds. In particular the rocky coast is home to breeding colonies of seabirds, including the endangered eastern population of the harlequin duck and is also on the Atlantic Flyway
migratory route for birds.

Threats and preservation

This ecoregion is almost entirely in its natural state, apart from some areas damaged by hydro-electric power generation projects and mining activities such as the

Richmond Gulf and the Clearwater Lakes on Hudson Bay, and Atikonak Lake
on the Quebec–Labrador border.
