  • Aspects of Offaly

Ireland's boglands are very special places. Boglands are areas of peat bogs and they make up 5% of the Irish landscape. They are home to many rare plants and animals.

There are two types of bogland in Ireland.

Blanket bogs are found on mountain slopes and in areas of heavy rainfall. They are not very deep, at about 1.5 metres. They are mostly found in the West of Ireland and in the Wicklow, Galtee and Knockmealdown Mountains.

How Bogs were Formed

Peat is a soil that is made up of the partially decomposed remains of dead plants. Over thousands of years, these plants have accumulated on top of each other in waterlogged places.Raised bogs were formed at the end of the last ice age, which is about 10,000 years ago. At this time, much of central Ireland was covered by shallow lakes left behind by the melting ice. Over the centuries, poor drainage and the build up of dead plants created layer upon layer of peat. Sphagnum (bog moss) is the most important plant in the formation of peat.
