Urban roadside lawns are a widespread component of urban green infrastructure and are simultaneously exposed to intensive management and chronic traffic-related environmental pressures. This dataset was collected to investigate the effects of mowing frequency and road proximity on soil conditions, soil temperature, and vegetation in urban roadside lawns.
The study was conducted in Kraków and Katowice (southern Poland) during two growing seasons (2023–2024). Fifteen experimental sites were established and divided into plots subjected to three mowing regimes differing in cutting frequency (one, three, or six cuts per growing season) and two positions relative to the road edge (road-adjacent and control plots). Soil samples were collected during four sampling campaigns covering spring and autumn seasons in both study years. Continuous soil temperature measurements were conducted at selected sites using dataloggers installed in experimental plots.
The dataset includes measurements of soil physicochemical properties (including soil texture, moisture, pH, electrical conductivity, nutrients, major elements, and exchangeable cations), time series of soil temperature, and quantitative vegetation data expressed as percentage cover of vascular plant species.
The dataset enables analyses of urban lawn responses to mowing management and road-related environmental gradients and supports investigations of biodiversity patterns, vegetation composition, soil conditions, and ecosystem functioning in urban environments.
