Forest of Motovun
The Motovun Forest is covered in old deciduous trees on the alluvial terrain along the river Mirna. The characteristic natural variety of tree growing in this forest is the pedunculate oak (Quercus robur), a usual species of the lower parts of continental Croatia. During the period of the Austro-Hungarian Monarchy, this forest was a reserve dedicated to the growing of wood securing the supply for shipyards of building timber. Today it is the largest intrinsic habitat in the world of the white truffle (Tuber magnatum Pico).
