‘Peat’ is an important source of domestic fuel in several countries.

Peat is formed from the wetland vegetation especially from the Sphagnum (bog moss).

Sphagnum likes to grow in acidic nature in the bog, due to the acidity the complete degradation of the cell could not take place due to the presence of less number of bacteria. Sphagnum uptakes water from the dead hyaline pores and holds a great amount of water. Due to the fossilization of Sphagnum, Peat is formed.
