Peat bogs are among the most interesting biotopes in Slovakia and form a rare type of wetland. Their existence is made possible by sufficient water. The permanently waterlogged biotope is covered by specific vegetation such as peat mosses or sedge grasses. In an oxygen-deficient environment, dead plant parts gradually accumulate layer by layer and form organic matter – peat. The formation of these layers is facilitated by a combination of excess water and limited oxygen.
