Calcareous tufa-forming spring fens are among the most endangered mire types worldwide. The restoration of spring fens is very complicated and the most crucial task is to restore a moss carpet. In 2010 we started with an experiment aimed to study the effect of N and P addition on the establishment and growth of the two key moss species on an area of spring fen that was formerly weakly drained but now has a raised up water table. Preliminary results indicated a positive effect of P (but not of N) on the growth of the Scorpidium scorpioides. The positive effect of P on the growth of Campylium. stellatum was less evident.
