The Structure of the Vascular Flora in the Manor Park in Laskowice

Abstract

Background. The manor park in Laskowice (Kuyavian-Pomeranian Voivodeship) was established in naturalistic style in the 19th century. Since then it has been transformed considerably. The aim of this paper was to analyse the structure of the vascular flora before revitalisation of the park and to present proposals of specimens of the dendroflora to be protected as natural monuments. Material and methods. In 2015 and 2016 vascular plants, including monumental specimens of the dendroflora, were inventoried, as had been commissioned by the current administrator of the Dąbrowa Forest Inspectorate. The vascular flora was analysed for life forms, geographical, historical, sociological and ecological groups. Results. There were 203 taxa of the vascular flora in the park, including 8 valuable species –endangered and protected. The Poaceae, Asteraceae and Rosaceae families were the most abund­ant. There was a large share of alien species in the flora (27%), among which kenophytes were the most abundant. Hemicryptophytes were the predominant life form, followed by phanerophytes, therophytes and geophytes. Species of the following classes of non-forest habitats were predominant: Artemisietea vulgaris, Agropyretea intermedio-repentis and Molinio-Arrhenathe­retea. There was a slightly smaller share of species of the Querco-Fagetea class. Both forest and ruderal species pointed to Tilio-Carpinetum as the potential forest community. Conclusions. The large share of alien species in the park flora indicated its anthropogenic character. The inventory of the flora provides the basis for revitalisation of the park with its natural values. 61 tree species and blooming ivy specimens were proposed for legal protection as natural monuments.
