Abstract
Prychepa M. 2021. Species diversity of wetland birds, depending on area, overgrowth of water
bodies on the example of sovskie ponds (Ukraine). Acta Biol. Univ. Daugavp., 21 (2): 111 – 116.
The influence of macrophyte pond overgrowth conditions on the formation of wetland avifauna
was considered. The model reservoirs were Sovsky ponds (Kyiv, Ukraine). In the course of
the research it was established that the largest number of species and the density of nesting
pairs of wetland birds on pond with an overgrowth area of up to 45%. In turn, the pond with an
overgrowth area of up to 10% was characterized by the smallest species diversity. In ponds with
macrophyte overgrowth areas of 45-65%, the dominant species was found to be the common
martin, the share of which was 27-51.72%, respectively. At the pond with an overgrowth
area of 90%, the dominant species were coots and mallards, which accounted for 25%. To
assess biodiversity, the Shannon Index was calculated, which was the highest in ponds with
overgrowth areas of 55-65%. Taking into account the peculiarities of avifauna formation in
conditions of natural succession on Sovskie ponds, it is possible to predict the negative and
positive consequences of overgrowing areas in other water bodies of the metropolis. The data
obtained can be used to further improve the ecological state of individual water bodies of the
cascade by managing water resources.
Key words: waterfowl, ponds, area overgrown, marcophytes, Shannon Index, biodiversity.
