The topic of this thesis is „Mangrove forests“. The paper defines the concept of mangrove forests as well as their division, specifics, importance and problems of degradation. The basis of the work is to understand importance of mangrove forests ecosystems and to explain possibilities of their restoration due to excessive destruction. The paper describes mangrove forests ecosystem (geographic distribution, division, biodiversity, adaptations and ecosystem services), describes the main causes of mangrove forests degradation and its impact on biodiversity and at the end are listed possibilities of restoring degraded ecosystems. Mangrove forests occupy 1% of the area of all tropical forests but their role and importance for the functioning of the entire world is much greater. Given that almost 40% of the area of mangrove forests has been lost over the last 50 years it is necessary, in addition to the protection measures already taken, to undertake greater efforts to restore these unique ecosystems.
