The distribution of fen pondweed (Potamogeton coloratus) restricted to Europe where it is one of the rarest and most threatened pondweed species. In Hungary, former data of fen pondweed originated mostly from thermal and karstic springs. Due to intensive bauxite mining activity in the edge of the Transdanubian Mountain Range (NW Hungary) these springs dried up by the end of the 20th century, and it caused the temporal extinction of the species. After the ceasing of mining activity many of the former karstic springs have regenerated and several fen pondweed populations have re-established. In this paper we summarized 18 population data of fen pondweed collected between 1999 and 2016. Many of them were formerly registered in the 19th century too. Most of the new and re-discovered populations were found in karstic springs or in artificial and natural lakes in the vicinity of these springs.
