The High FensJalhay
On the High Fens are fields with heather on dry parts and marshes where there is poor water drainage. The Fens are normally more in the northern and higher parts. The climate is moist and cold and soil and landscape all contribute to a very unique flora and fauna.
The weather conditions at the High Fens are caused by a western flow coming from the Atlantic Ocean, with cool and saturated air. Increase in saturated air at the high plateau results in high annual rainfall (more than 1400 mm per year). A rocky soil with a high clay content leads to low permeability and infiltration of water in the soil. Water remains in bowls where over eons by accumulation of dead plant material and anaerobic conditions, thick packages of peat occur.
