Item Białowieża Forest (NE-Poland) and Valday NP (NW-Russia) – biogeographical characteristics of eutrophic deciduous forests(Wydział Nauk Geograficznych i Geologicznych Uniwersytetu im. Adama Mickiewicza, 2014) Matuszkiewicz, Jan Marek; Bielonowska, Elena; Kowalska, Anna; Cariewska, Nadjeżda; Baranowski, Jarosław; Vinogradowa, Viera; Tishkov, Arkadij; Litvinova, ElenaDuring geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia), rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Białowieża National Park (NE-Poland) indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.
