Mires are habitats in which peat is slowly produced from the remains of living species. Mires are plentiful in Finland, because the cold and humid climate and acidic soil provide good conditions for their formation.

Some type of mires, such as spruce (hardwood) swamps and pine swamps, can have trees, whereas other mire types, such as open (treeless) bogs and fens, have lower vegetation. Some mires are different combinations of the aforementioned types.
