Non-metric multidimensional scaling (NMDS) ordination, based on a Euclidean similarity matrix of lake physico-chemical parameters. Symbols represent the water environment of Bliz (blue dot), Tri (coral quadrate), Rib (green diamond) and Dol (brown triangle) in pre-restoration period (pre), August (A23) and October (O23) 2023 and October 2024 (O24). Two-dimensional stress = 0.11.
