Figure 1

Study area – Biebrza National Park and its buffer zone. Localization of measurement points: grasslands – bright green; reed communities – green; sedge communities - purple; red dots – measurement points. The background is a mosaic of Sentinel-2 images for Poland which was prepared in 2020. Available via WMS (IGiK, 2020)Source: own elaboration
