The main purpose is preservation of the area of Inhul river valley with its typical and unique natural complexes (fragments of virgin steppe, granite outcrops, waterways and forest plantations).
Here limestones, clays and sands lie on Precambrian formations – gneisses and granites which outcrop in some places along the valleys of the river Ingul and its feeders the Sagaydak and the Berezivka creating unique attractive landscapes, the isotopic age of which is determined by geologists to be 1.8-2.2 billion of years.
In spring various landscape formations are wonderfully decorated with [Potentilla arenaria], [Aurinia saxatilis], several species of violets, Corydalis solida, Scilla bifolia, Tulipa hypanica, Iris humilis and in summer – with the rainbow mosaic of the motley grass steppe.
Cattle pasture, recreational loads, amateur fishery, poaching in the area of Sofiivske water reservoir, steppe and forest fire deplete the fauna of RLP, which, however, is much better preserved than in the bordering agrolandscapes.
The list of rare and threatened species being under protection of the State includes Southern Festoon (Zerynthia polyxena), Old World Swallowtail (Papilio machaon), Mammoth Wasp (Scolia maculata), Carpenter Bee (Xylocopa valga), Large Whip Snake (Coluber jugularis), Long-legged Buzzard (Buteo rufinus), Stoat or Ermine (Mustela erminea), Steppe Polecat (Mustela eversmanii) etc.
