Vascular plant species list of managed oak stands in the Bory Stobrawskie Forest (SW Poland, Central Europe)

This is the second version of the species list, which has been expanded to include additional ecological and statistical information for each species. The data were collected in the summer of 2023 from 100 circular plots (each measuring 314 m²) located in forest stands aged between 41 and 180 years, which were dominated by oak trees —pedunculate oak (Quercus robur L.) and/or sessile oak (Quercus petraea (Matt.) Liebl.). The study area was situated in the Bory Stobrawskie mesoregion in the Opole voivodeship, Poland (50°31'-50°59'N, 17°40'-18°35'E). The species list includes the percentage frequency, fidelity, and average cover values, which were calculated using the JUICE software for all plots and for plots located in middle-aged (41–80 years) and old (100–180 years) stands. For each species, information is also provided on: life form, life strategy and forest species category. The newly added data includes information on whether a species is considered an ancient forest species, its ecological indicator values for soil moisture, soil nitrogen, soil reaction, light, and temperature, and its rarity in Poland.
