PROJECT DESCRIPTION
BACKGROUND
Alkaline fens (a habitat type listed in Annex I of the EU Habitats Directive) are one of the most valuable and ecologically interesting – and also one of the most difficult to protect – of European ecosystems. Their functioning is conditioned by interaction of external factors such as the appropriate geological conditions (the presence of rocks and minerals of a suitable chemical composition) or the proper functioning of the regional hydrological system. Well-preserved fragments of these ecosystems are home to large number of endangered and protected species of flora and fauna.
The intensive drainage of wetlands in the 20th century has led to the disappearance of some 80% of Poland’s alkaline fens.
The extreme risk to Polish alkaline fens has been confirmed by the results of an inventory of habitats carried out by the project beneficiary, Klub Przyrodników, during 2008-2011. This indicated that only 10-15% of the country’s alkaline fens have characteristic vegetation. From hundreds of inventoried samples only 34 were selected in northern Poland, which at the same time is the area of the most important refuges in the country of the rare plant species marsh saxifrage (Saxifraga hirculus), fen orchid (Liparis loeselii) and slender green feather moss (Hamatocaulis vernicosu). Amongst the sites selected by this project are the most valuable alkaline fens of the valleys of Biebrza and Rospuda, Lake Sejny, Augustow Forest, and the Kashubian Lake District.
OBJECTIVES
The ‘AlkFens_PL’ project will focus on the protection of alkaline fens in 35 Natura 2000 sites located in northern Poland. This large-scale project is potentially of great significance since the project area incorporates some 70% of the total alkaline fens of northern Poland. The general objective is to prevent their degradation and to achieve or maintain “favourable” conservation status. This will have the consequence of improving the conservation prospects for the many associated rare and endangered plants they support.
