EN In 2017, a new site of the Water Caltrop Trapa natans was discovered in the Lower Odra River Valley near Szczecin (NW Poland), afer nearly 90 years of its extincion in northern Poland. In 2018, during the monitoring of this population, it was shown that the species had extended the range and colonized new sites in the valley, including Lake Dąbie. Currently, the population of Water Caltrop near Szczecin spreads over a length of about 14 km and covers an area of about 2.6 ha. Te biggest threat for this population is the implementation of a flood protection project involving the Odra river, in which it is planned to deepen the canal in the immediate vicinity of the largest concentration of the Water Caltrop.
