The article submit flora and diversity investigation of the shore grass vegetation of the pond cascade of the natural monument “Schelokovsky woods park” on the area of the metropolis Nizhny Novgorod. The ratio of the environmental groups of flora and vegetation were determined concerned to humidity. The indices of species richness, diversity and evenness of species (Margalef Shannon, Simpson, Pielou) were estimated., a cluster analysis of spatial heterogeneity was made, and the environmentak conditions were indicated with D.N. Tsyganov score scale. The disturbance of vegetation on the banks of water bodies was assessed by the participation of ruderal species in the composition and cover abundance.
The subject is flora and diversity of grass vegetation in shore protection zone of Lake Lunskoye on the Volga floodplain nearly the metropolis of Nizhny Novgorod. The proportion of the environmental groups of flora and vegetation cover was estimated concerned to soil moisture by means of Landolt five-graded scale. The indices of species richness, diversity and evenness (Margalef, Shannon, Simpson, Pielou) were measured, a cluster analysis of spatial heterogeneity with Morisita-Horn β-diversity index was made, and the The disturbance of vegetation on the shores was assessed by the participation of ruderal species (weeds) in the composition and cover abundance of herbaceous assemblages. The practicality of catchment protection is revealed, thus the regional legislative conservation of the natural landscape and environmental framework would be enhanced thereby contributes to the development of Sustainable Development of Goals 3, 11 and 15 on the natural areas of Nizhny Novgorod.
