Knowra Hudson Bay Lowlands Hudson Bay Lowlands The Hudson Bay Lowlands are a vast, low-lying region of wetlands and tundra along the southern and western shores of Hudson Bay in Canada. Their waterlogged terrain formed on land recently uncovered by retreating glaciers and the bay’s gradual rebound.
Hudson Bay : A large inland sea in northeastern Canada, bordered by Ontario, Quebec, Manitoba, and Nunavut. The lowlands fringe its southern and western shores.
Peatland : A wetland where partially decomposed plant material accumulates as peat. Peatlands cover extensive areas of the Hudson Bay Lowlands.
Polar bear : A large Arctic bear adapted to life on sea ice and along northern coasts. Polar bears use parts of the Hudson Bay coast and nearby tundra.
Hudson Bay taiga : A subarctic forest ecoregion bordering Hudson Bay, with coniferous woodland and open wetlands. Taiga borders the lowlands inland, where trees become more prominent.
Canadian Shield : A vast area of exposed Precambrian rock surrounding Hudson Bay and extending across much of Canada. Shield bedrock borders the lowlands and shapes their western landscape.
Bog : A peat-accumulating wetland fed mainly by precipitation and typically dominated by mosses. Bogs are a major peatland type in the lowlands.
Wapusk National Park : A national park in Manitoba protecting subarctic tundra, peatlands, and polar bear denning habitat. The park preserves a representative part of the lowlands near Hudson Bay.
Arctic tundra : A treeless biome of the Arctic, shaped by cold temperatures, permafrost, and a short growing season. The lowlands include tundra but also extensive southern wetlands and peatlands.
Pleistocene : The geological epoch from about 2.58 million to 11,700 years ago, marked by repeated glaciations. The last glaciation shaped the terrain underlying the lowlands.
Fen : A peat-forming wetland supplied by groundwater or surface water and often rich in sedges. Fens occur where mineral-rich water reaches the peat surface.
