It is the smallest species of deers. During the winter it can be seen in lower altitudes, while in the summer it moves higher depending on the availability of and the quantity of food. It can live in various forest habitats (deciduous or mixed conifer forests) and occurs in big numbers in central and northern Europe. In Greece, only small populations of roe deer have been left at the mountainous regions of the mainland. The species is now characterized as 'vulnerable', meaning that if it continues being exterminated it will soon face extinction.
