The main advantage of the usage of that nature reserve was in the long duration of its existence and making the long-term series of observations as recorded in the annals of nature (recording of climate data, biological processes, and human influence).

The first was the absolutely protected areas of forest and steppe which were connected with territories strictly controlled haymaking or grazing.

Here, the existing semi-natural ecosystems kept saved and the small arrays of oak forests with black soils were the most valuable territories.

The mine dumps and territory of nuclear power stations near Kursk was included to the transition zone.

[4] Although CCZ is one of the smallest reserves in the federal network, it is highly important from a scientific point of view as a collection of preserved remains of northern grasslands in the Kursk region.

Reserve management refers to its "six patches of paradise",[1] with virgin northern steppes, black earth prairie, pre-glacial vegetation on chalk hills, relict sphagnum swamps, and floodplain complexes.

The black soil, which derives its color from a high humus content (540 tons/hectare) is unusual for being under deciduous forest, and reaches a depth of 1.5 m (4.9 ft).

This climate is characterized by large swings in temperature, both diurnally and seasonally, with mild summers and cold, snowy winters.
