What is a Bog?
During the last ice age, Ireland was covered in snow and ice. When the ice melted, lakes formed. Plants grew around the lakes. After many years, they died and sank to the bottom of the lake. After hundreds of years, the lake became full of dead wetland vegetation. This transformed into what’s called a fen. New plants such as sphagnum moss, began to grow on the surface of the fen. Over thousands of years, the sphagnum moss died and accumulated, and peat began to form. At this point, the fen became a bog. Trees began to grow on the bog and later died. As the peat accumulated, the bog grew higher, like a dome. It became known as a raised bog.
