Design of sample collection routes for ecological phytodiagnostics of urban geosystems

Empirically, pedestrian paths that are safe in an actual aspect have been established, connecting the sites of trial sites of the monitoring network used in phytoindication and examination of the state of ecotopes in the Donetsk city district. The optimal route for sampling (at least 5–7 times during the growing season) in the impact zone of the Kalinin coal mine dump was compiled and visualized, as well as differentiated route schemes in the Kalininsky and Voroshilovsky districts of Donetsk city and adjacent territories, including sections of the Kievsky district and the city of Makeyevka. The developed routes were tested in 2023–2024 in the environmental phytomonitoring system of Donbass.
