Chalk Flora Nature Reserve (Ukrainian: Крейдова флора (заповідник)) (also: Cretaceous Flora) is a protected nature reserve of Ukraine that lies on open chalk slopes of the riverine hills along the Donets River. The reserve is in the Kramatorsk Raion of Donetsk Oblast.[1] [2] it is a sub-unit of the Ukrainian Steppe Nature Reserve, with an area of 1,134 hectares.
The ridge is about 50-70 meters above the surrounding territory, and steep - up to 70 degrees. The area has been preserved in large part because the land is not suitable for agriculture.
The climate of Chalk Flora NR is Humid continental climate, warm summer (Köppen climate classification (Dfb)). This climate is characterized by large seasonal temperature differentials and a warm summer (at least four months averaging over 10C, but no month averaging over 22C.[3] [4]
About a third of the reserve territory is forest, surrounded by steppe. The forests are typically of chalk pine or birch. The steppe is of the multi-grass variety found in the mid-Ukrainian regions, on chalky soils and sow-hummus black soils.
As a strict nature reserve, Chalk Flora's primary purpose is protection of nature and scientific study. Public access is prohibited.
