There are 3 large carnivours living in Croatia, and one of them is the Eurasian lynx (Lynx lynx). There are 4 living species of lynx: the Eurasian lynx, the Iberian lynx, the Canadian lynx and the Red lynx. The Eurasian lynx is the largest of them all. In the Croatian territory, its main prey is pair-toed deer; mostly deer and roe deer. When the food is not deer or roe deer, then it feeds on smaller animals and birds. In Croatia, the Eurasian lynx is found in the area of the Dinarides. In addition, the lynx likes a solitary life, and just during mating males are finding females. Man has a great effect on nature and animals with his hunting and construction of roads, and thus also affects the lynx. The Eurasian lynx has already died out in our area once, and because of this, the lynx was reintroduced to this area in 1973. The population grew, but over time this growth began to stagnate and now this population is once again subject to extinction. In order to prevent another extinction, it is necessary to introduce new individuals into the population to increase the genetic diversity of the population. This is taken care of by the LIFE Lynx international project, which operates in Croatia, Slovenia and other countries.
