As a result of water regulation in the past, periodically exposed natural habitats with vegetation of the class Isoëeto-Nanojuncetea in Slovakia and the surrounding Central European countries have recently become scattered. Many of its characteristic species have, however, found opportunities for living in secondary habitats such as water reservoirs or field depressions. While much research has been carried out on amphibious vegetation in Slovakia, no data drawn from the Liptov Basin have been published to date. Here we provide the first vegetation survey of exposed banks of the Liptovská Mara Dam, four decades after its construction. Vegetation analyses identified three groups. Cluster 1 gathered on regularly exposed banks with nitrophilous perennial vegetation (Bidenti-Polygonetum hydropiperis and Rumici crispi-Agrostietum stoloniferae). Cluster 2 was found in the middle zone formed by annual stands and was the most widespread vegetation type within the studied object. In the newest surveys from the Czech Republic and Slovakia, vegetation with the same species composition was reported as Cyperetum micheliani. Comparison of those data with ours revealed that stands from Liptovská Mara belonged to the association Junco bufonii-Gnaphalietum uliginosi. Finally, cluster 3 grouped the most rarely exposed shores, with dwarf annual vegetation blocked by repeating inundation (Eleocharito acicularis-Limoselletum aquaticae). The length of flooding, slope and soil texture were the primary factors affecting the zonation of plant communities. Despite the secondary origin of the study object, the species composition is natural, and spreading of neophytes was not detected. In the case of such an artificial habitat, this is a remarkable finding.

过去由于水的管制，斯洛伐克和周围中欧国家的定期定期暴露的自然栖息地的植被都属于Isoëeto-Nanojuncetea类。然而，许多其特有物种已经找到了生活在次生栖息地（如水库或田野洼地）中的机会。尽管已对斯洛伐克的两栖植被进行了大量研究，但迄今为止，尚未公开任何来自利普托夫盆地的数据。在这里，我们对LiptovskáMara大坝建成40年后的裸露河岸进行了首次植被调查。植被分析确定了三组。聚类1聚集在定期暴露于具有多年生氮的植被（Bidenti-Polygonetum hydropiperis和Rumici crispi-Agrostietum stoloniferae）。聚类2位于由年生林分形成的中间区域，是研究对象内分布最广的植被类型。在捷克共和国和斯洛伐克的最新调查中，据报道具有相同物种组成的植被为莎草（Cyperetum micheliani）。将这些数据与我们的数据进行比较后发现，LiptovskáMara的林分属于Junco bufonii-Gnaphalietum uliginosi协会。最后，第3类将暴露最稀疏的海岸归为一组，一年生植被被重复淹没而阻塞（Eleocharito acicularis-Limoselletum aquaticae）。洪水时间，坡度和土壤质地是影响植物群落分区的主要因素。尽管研究对象是次要起源，但物种组成是自然的，未检测到新植物的扩散。在这种人工栖息地的情况下，这是一个了不起的发现。
