According to the results of the research, it was established that the flora of vascular plantsof the Luga River is 119 species, the faunal complex is represented by 80 species of animals ofthe mammal class – 3 species, birds – 23 species, amphibians – 2 species, fish rays – 6 species,earthworms –1 species, crustaceans – 2 species, arachnids – 2 species, insects – 28 species,molluscs – 12 species. The following families are the most numerous in terms of the number ofgenera and speciesAsteraceae, Poaceae, Lamiaceae, Apiaceae, Brassicaceae, Polygonaceae,Rosaceae. It is these families that have the greatest floristic diversity and occupy a leading placein the study area, and their spectrum is evidence of a strong anthropogenic influence on thevegetation cover.Various biotopes have formed in the floodplain of the Luga River and along its periphery,which differ in structure and varying degrees of transformation. The plant species composition ofthe floodplain of the Luga River is represented by typical aquatic, coastal-aquatic macrophytesand mesophytic forbs of floodplain meadows. The largest areas are occupied by monodominantgroups of Phragmites australis and Glyceria maxima, in smaller measures Typha latifolia. Theanimal world of the Luga River and its floodplain is represented by 16 species of hydrobiontsand 13 species of amphibiotic animals. Mammalia – 1 species, Aves – 6 species, Amphibia – 2species, Actinopterygii – 6 species, Crustacea – 1 species, Insecta – 6 species, Bivalvia – 2species, Gastropoda – 6 species.The marginal biotopes of the terraces are characterized by the dominance of ruderalcommunities with a significant participation of adventive plant species. The rarity component ofthe flora is represented by rare groups of yellow pitcher plants (Nuphareta luteae). Intensiveprocesses of natural overgrowth of the Luga River bed have been noted, which causes the flow toslow down, silt to accumulate, and the species composition of plants and animals to change. Thestudy area is characterized by high phytocenotic activity Аcer negиndo, Echinocуstis lobata,Solidago canadensis, Heracleum sosnowskyi, Heracleum mantegazzianumm etc. The animalworld of the edge terraces is represented by 64 species of animals. Mammalia – 3 species, Aves– 20 species, Amphibia – 2 species, Crustacea – 1 species, Arachnida – 2 species, Insecta – 28species, Gastropoda – 4 species.The main trends and threats caused by the anthropogenic factor have been identified:increased recreational load and accompanying degradation of vegetation due to direct impact onareas of mass gathering of vacationers, which leads to the disappearance of typical coastal-waterspecies of plants and animals associated with them, transformation as a result of anthropogeniceutrophication, which leads to a change in the structure of macrophyte and hydrobiontcommunities. The transformation of plant cover and animal complexes takes place in thedirection of replacing natural species with apophytes and adventitious plant species,synanthropic animal species and plant pests that are more resistant to anthropogenic influence.
