| Summary: | Background. The biological diversity of the “Karnovarsky solonetz”, located in
the south-west of the Penza region (Neverkino district), is analyzed. The halophytic vegetation of the forest-steppe zone of Eastern Europe has been little studied and
these studies practically did not concern the Penza region [1, 2].
Materials and methods. The study of vegetation was conducted 2018–2019 using
the method of geobotanical profiling, collected 122 trial sites. An ecological-phytocenotic
classification of vegetation on a dominant basis has been developed.
Animals in the area were studied from 2014 to 2019.
Results. “Karnovarsky solonetz” contains halophytic vegetation (73,7 %), halophytic
meadows (18,1 %) and halophytic bogs (1,6 %). Non-halophytic vegetation
on the solonetz (26,3 % of the area) includes steppe (19,0 %), meadow (5,6 %) and
shrub vegetation (1,6 %). The main stages of the demo-halophytic steppe, meadow,
and bog vegetation, which proceed as well as in other southeastern solonetzes (Neverkino
district), are distinguished. Flora includes 124 species of vascular plants, of
which 1 species is listed in the Red book of the Russian Federation (2008) [3] and
16 in the Red book of the Penza region (2013) [4]. The study of animal fauna is at
the initial stage of study: 70 species of animals have been discovered: vertebrates –
14 species and invertebrates – 56 species, of which 5 species are listed in the Red
book of the Penza region [5].
Conclusions. We recommend the creation of a new natural monument in the Neverkino
district, 2 km from the village of Mаnsurovka under the name “Karnovarsky
solonetz”.
