Mardakan arboretum is from the shore of the Caspian Sea. The territory of the arboretum is 12 hectares. 80–85% of the arboretum is covered with limestone. The soil cover is represented by various soil combinations. With increasing distance from the sea heavier and lighter sandy-loam grounds are encountered, which consists of insignificant depth of 0.5 to 1.5 meter. Only natural lignose and shrubs are almost absent. Cascara buckthorn, Georgian honeysuckle, tamarix, feral fig and other plants are encountered between the rocks.
