Semi-natural ecosystems in Poland and all over Europe have become endangered due to succession. A more effective plan of protection of these ecosystems can only be developed when based on thorough knowledge of the habitat requirements, successional pathways and related threats. Studies conducted in a nature reserve were aimed at defining the most important changes observed in non-forest communities under uninterrupted secondary succession conditions since a reserve was erected.
Several years of strict protection within the reserve resulted in the partial disappearance of non-forest habitats. Their area is now three times smaller than it was in the mid-20th century. Meadows described in the 1960s have undergone different transformations. The meadows have been replaced with initial forest communities that belong to the dynamic circle of riparian, alder, and oak-hornbeam forests.
