A rare and protected species of the sedge Carex secalina was recorded in Dulsk near Inowrocław (Kujawy-Pomerania Province) in June 2014. It occupied the shores of ephemeral midfield water reservoirs in the complex of intensively used crop fields. Two subpopulations of this sedge with 36 tussocks in total were found. In the first subpopulation, the tussock diameter reached up to 25 cm, with 12–16 generative shoots per a tussock, while in the second subpopulation, the diameter was up to 10.5 cm, with 2–11 generative shoots. The rapid spread of this halophyte species is probably connected with the presence of permanent soil seed bank. This observation indicates a high potential of Carex secalina to colonise new habitats.
