Species diversity assessment of shore vegetation as a basis for environmental indication and tuning for environmental management (focused on wood park ponds cascade in a metropolis)

Abstract

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.
