Historyczne parki Londynu i Warszawy, konserwacja, utrzymanie drzew i drzewostanów na podstawie wybranych przykładów

The aim of the study was to develop proposals in order to improve the maintenance of selected heritage parks in Warsaw, with particular emphasis on trees and tree stands. Analyses leading to this, consist in showing the differences and similarities in the functioning and use of heritage parks in London and Warsaw. As a result of applying the adopted criteria, Kensington Park, Greenwich Park, Łazienki Królewskie and Ogród w Wilanowie were compared. Literature and field studies were carried out. The research was enriched with a survey on the evaluation of parks filled in by visitors. Based on the research, both parks were analysed in a descriptive form, supplemented with photographs, and the comparison between them. The greatest differences in the method of maintaining and managing both parks and their reasons were indicated. The differences in the species composition of trees were shown, incidental to including from historical and climatic conditions. It was found out that: in Warsaw there is no organisation associating with heritage parks, there are no long-term management plans. The process of issuing care decisions is complicated, what causes delays in their implementation, in Warsaw parks veteran trees are not isolated and they are not treated specially. External companies dealing with parks and tree stand conservation are employed one-off, which contributes to the lack of continuity and responsibility for the work performed. Proposed solutions may help to improve the management of Warsaw parks and contribute to the improvement of the condition of parks and their trees.
