Local and landscape features of the urban flower meadows

The dataset includes raw data on: 1) landscape variables, and 2) the internal structural characteristics of urban flower meadows. The study was conducted in 2021 across all open green areas designated as urban flower meadows (n = 55) in three major Polish cities (each with >290,000 inhabitants): Białystok (BI) (53°07′59″N, 23°09′51″E), Bydgoszcz (CB) (53°07′24.6″N, 18°00′27.43″E), and Łódź (EL) (51°45′00″N, 19°28′00″E), located in the northern, central, and eastern parts of Poland, respectively.Urban flower meadows varied in size and vegetation cover, ranging from approximately 80 m² to 5,000 m². Landscape variables—specifically features of the urban matrix—were characterized based on Urban Atlas 2018 maps (Copernicus, 2020), which describe 20 different types of urban land use (Table S2). These maps were downloaded from the Copernicus servers for Białystok, Bydgoszcz, and Łódź. The internal characteristics of the urban flower meadows were assessed within each area as part of a biodiversity survey.
