About the Hudson Plain

The Hudson plain or Hudson plains is a subarctic ecoregion located in Canada, south of the Hudson bay, and created by the proximity to this body of water. It contains the largest contiguous wetland in the world. The climate is cold, and humid relative to other regions of similar temperatures, and the geography is flat.

Vegetation is sparser than in the Taiga regions to the east and west and also much sparser than the Northern Forests which lie to the south. The area ranges from bogs in the north to open forest in the south. The climate is slightly more moderate than in the bordering Taiga region, but winters are still very cold. The northernmost part of this region has permafrost like in the tundra, but it becomes sporadic as one moves southward.
