Ecoregions are areas that have distinctive, recurring patterns of vegetation and soil development, that are determined and controlled by local climate and geology. Also called "natural regions," ecoregions differ from each other in their combinations of plant communities, landscapes, geology, and other features.

Sub-categories of ecoregions, subregions are smaller areas which differ slightly from each other in geology and geomorphology (how surface landscape features are formed).

Nine ecoregions have been identified on the island of Newfoundland, and ten in Labrador, thanks to the founding work of Dr. A.W.H. Damman and then Susan J. Meades. In addition, several of the Island's ecoregions can be further broken down into 21 subregions (sometimes called ecodistricts). More research is required to identify subregions in Labrador. This makes 35 natural regions in the province.


The province's ecoregions and subregions provide habitat for 1,406 known species of vascular plants, 13 indigenous mammals (on the Island) and 37 in Labrador, and 73 species of birds that commonly breed here. There are also thousands of invertebrates (insects and worms), fungi, and algae and countless micro-organism species, all of which are vital to our ecosystems.

Because of the latitudes and area the province spans, many plant and animal species attain their northern or southern limits here.

The design of many of the current and future protected areas in the province is based on protecting representative and pristine portions of all of our ecoregions and subregions. This, in turn, should play a key role in ensuring the survival of all plant and animal species, into the future.
