Peatlands form where climate, bedrock and relief create areas with permanent water saturation. They either develop in shallow waters over layers of lake sediments (this is called terrestrialisation) or directly on mineral soils (known as paludification). There are two major types of peatlands: 1. Bogs which are only fed by rain. Bogs are therefore nutrient poor, acidic, and often elevated over the surrounding mineral soil, and 2. Fens which are also fed by water coming from mineral soil/bedrock and are usually less acid and richer in nutrients.
