Taxonomic structure of the flora of water bodies located in the zone of influence of the JSC “SLPC” (Komi Republic)

The analysis of the taxonomic structure of the flora of water bodies located in the zone of influence of the largest forestry enterprise in the European North-East of Russia – joint stock company (JSC) “SLPC”. The flora of impact reservoirs in the zone of influence of JSC “SLPC” unites 119 species of macrophytes belonging to 77 genera and 43 families. Flowering plants in its composition are represented by 114 species, and cryptogamic ones by five: vascular spore plants by two, bryophytes by three. It was found that the role of the Potamogetonaceae family and the genus Potamogeton was significantly reduced in the floras of impact reservoirs, while the role of the Asteraceae and Poaceae families was simultaneously increased. The flora of reservoirs located in the zone of influence of JSC “SLPC” have a high degree of transformation: the flora of anthropogenic reservoirs is 100.0% composed of synanthropic species. The most active among them are Bidens cernua L., Bidens tripartita L., Lycopus europaeus L. and Typha latifolia L. The flora of anthropogenically transformed reservoirs are also significantly synanthropized (Is=98.4–100.0%), the basis of their flora is apophytes. In anthropogenic reservoirs, vascular spore and moss-like plants are completely absent. The taxonomic structure of the flora of anthropogenically transformed reservoirs retains similarities with the flora of the reservoirs of the region. The analyzed flora includes species protected on the territory of the Komi Republic: Riccia cavernosa Hoffm. and Carex pseudocyperus L.
