SUCCESSION OF PLANT COMMUNITIES IN PEAT EXTRACTION PITS BASED ON MACROFOSSILS AND CURRENT PLANT ANALYSIS
Published: 1 Nov 2023
Abstract: The small water bodies formed after peat excavation undergo spontaneous succession, and the hydrological factor plays a key role in this process. Plant organic matter deposited in the conditions of high wetness retains the structure of plant tissues; hence, it is possible to identify vegetation that forms subfossil communities and reconstruct the succession series by analysing macroscopic plant remains. The aim of the present study was to identify the sequence of the succession series in the post- excavation peat pits of the Łęczna-Włodawa Lakeland by analysis of plant macrofossils.Depending on trophy conditions and water layer thickness, various communities are responsible for initiation of the peat-forming process in the analysed objects of the Łęczna-Włodawa Lakeland. These include underwater Chara meadows (Ostrówek Podyski object), rush communities from the alliance Magnocaricion (Jelino and Krasne objects), and bryophyte communities forming a floating carpet over an open water surface (Podlaski object). The analysed post-excavation pits are currently undergoing a transitional phase of overgrowing. They have become refugia for many rare and protected plant species, e.g. Rhynchospora alba, Scheuchzeria palustris, or Menyanthes trifoliata.
