Regeneration of vegetation in manor park in Laskowice (Dąbrowa Forest District)

Abstract

Laskowice is a village located in Kujawsko-Pomorskie Voivodeship, in Świecie Upland near Świecie. On the edges of the village there is a manor-palace complex established by Franz von Gordon in the first half of the 19th century. Since the palace was destroyed in 1945, the maintenance of the park was ceased. Currently the object is administrated by Dąbrowa Forest District. The aim of the study was to determine the direction of vegetation transformation of the park in the light of lack of use. Lack of human interference within examined object has initiated regeneration processes. At present the vegetation of the park refers to structure and species composition of natural forest plant communities. Phytosociological research carried out in 2015 and 2016 revealed the presence of following associations: Ficario-Ulmetum , Fraxino-Alnetum and Tilio-Carpinetum. Shrub vegetation of Rhamno-Prunetea class develops in places. Non-forest vegetation of meadows ( Arrhenatheretum elatioris ) and nitrophilous edges ( Urtico-Aegopodietum ) are present. In case of analyzed object the physionomy and species composition of forest communities differs from typical forms. An attention is paid to a strongly developed layer of brushwood. There is a lack of some characteristic species, alien species are present in treestand and shrub layers. A large share in phytocoenoses of Ficario-Ulmetum and Tilio-Carpinetum has Sambucus nigra and in case of the first association also alien species – Philadelphus coronarius and Symphoricarpos albus . Values of calculated indices of synanthropization confirm the regeneration of forest communities: index of natural character achieves value 40% and synanthropization index ranges from 48.78% for Tilio-Carpinetum to 60.00% for Fraxino-Alnetum.
