The State Forests undertake their own protection initiatives, at the same time helping the chosen animals and plants species to inhabit the places, where those species became extinct (so called "species reintroductions)") or, where those species are threatened with extinction (so called "species restitutions"). Such actions concern, among others, European yew, European silver fir (in the Sudety area), black grouse and western capercaillie. 

Chances for survival of endangered species are to enlarge protection  areas for the chosen animals ( among others around bird nets). They constitute particular territory the foresters are responsible for, because most of them belong to the areas managed by the State Forests (LP).
