ALKALINE FENS IN POLAND Alkaline fens have been the subject of particular interest of the Naturalists’ Club for over 20 years. Based on conducted inventory, field research and knowledge acquired thanks to them, we undertook many conservation measures through- out Poland. The experience we gained was shared in our pu- blications, published as part of the implementation of pro- jects for alkaline fens protection in northern and southern Poland. This book is an attempt to summarize the knowled- ge we have had so far and which we had gained over the past few years implementing projects for their protection throughout the country. We would like to dedicate this book to all people involved in the protection of alkaline fens, the most valuable ones – like in the Rospuda river valley as well as many other in the other corners of our country. To those supporting us, co- Alkaline fens in Poland – diversity, resources, conservation resources, – diversity, fens in Poland Alkaline -workers, in particular one who stays in our memory - Jola Kujawa-Pawlaczyk, who contributed to protection of many peatlands.
