"The Polish State Forests is the largest organisation in the European Union managing forests which belong to the State Treasury. They manage almost one third of Poland’s territory considered particularly valuable as it is overgrown by forests. 
About 60 percent out of 618 vertebrate species that occur in Poland live in forests. Civilization progress imbalanced the longtime stability of forest ecosystems and its rules, which impact the animals that live there. Therefore, the number of animals, the manner of game keeping and the possibilities of preventing damages caused by animals are regulated by the Polish and EU law." - Polish State Forests
