Vegetation cover of artificial water bodies of the Upper Volga

Preliminary results of a study of the flora of various types of artificial reservoirs in the Upper Volga region (diggings, flooded sand and peat quarries, ponds, small reservoirs) are presented. Based on our own observations and literature data, it was established that the flora of technogenic reservoirs includes both macroalgae (4 species) and vascular plants (89 taxa). On the basis of floristic indicators, groups of similarities of water bodies were identified, which are likely to be formed depending on the nature of the occurrence of the reservoir, its morphometric parameters, the dynamics of the water area and coastal zone, and the nature of use.
