Comparative characteristics of avifauna of the Syrdarya River delta lakes system (Kartma, Karakol, Raimkol, Shomishkol lakes)

Abstract

For the first time, a comparative analysis of the quantitative composition of the avifauna of the lakes system of the Syrdarya River delta was carried out. Using the example of the lakes Kartma, Karakol, Raimkol, Shomishkol, the dynamics of the numerical composition of the bird population of the reservoirs of the lakes system of the Syrdarya River delta, under the conditions of the ongoing restoration of biodiversity, is presented. Lake Kartma is an offshoot of the Great Aral Sea, from 1988 to 2008 the area of the reservoir's water area has sharply decreased, since 2009 the water balance in the lake is maintained by the Syr Darya River, through the channels and branches of the Karateren - 1, 2. The reservoirs Karakol, Raimkol, and Shomishkol were selected as objects of comparison. The analysis of the results of bird counts indicates a gradual resumption of the avifauna of the model reservoir, in addition, in terms of individual quantities of quantitative composition, Lake Kartma is ahead of comparable reservoirs. A possible reason for the latter may be the presence of dense, impassable thickets of reeds in the central part of the lake, providing comfortable conditions for nesting and resting birds. It is recommended to restrict or ban hunting of waterfowl, in particular plate-billed ones, in Lake Kartma.
