Vascular plant flora of selected water reservoir margins in Gdańsk (northern Poland), 2014

This dataset contains occurrence records of vascular plants recorded at the margins of 40 water reservoirs located in Gdańsk (Pomeranian Voivodeship, northern Poland). The study was conducted during the 2014 growing season as part of a floristic inventory carried out for a master's thesis at the University of Gdańsk. Each reservoir was treated as a separate sampling site, including the flood zone and adjacent embankment. The dataset includes species presence data with semi-quantitative abundance estimates. The study aimed to provide a comprehensive inventory of vascular flora, assess species frequency and distribution, including alien and invasive taxa, and evaluate the floristic value of the investigated reservoirs. Voucher specimens were deposited in the Herbarium of the University of Gdańsk (UGDA).
