The aim of the study was to assess the state of health of 7 monumental trees which are the remains of gardens by the historic villas date back to the beginning of the 20s of the 20th c entury. Currently, 2 trees are located in the right- of-way, and the rest of the specimens are protected while as the part of Nature and Culture Landscape Parks, which include gardens in Parkowa Street. PiCUS Sonic Tomograph was used in the research which was based on the method of acoustic tomography, which uses the characteristics of a sound wave generated at the periphery of the trunk, providing information about the state of wood in the cross-section of the trunk. The state of health of 3 trees was rated as good, whereas inside 4 other trees inner cavities were found. It is expected that further development of damage will worsen the static condition of the trees and thus it will constitute a potential threat to the inhabitants of the city. Condition of the tree and thus it will constitute a potential threat to the inhabitants of the city.

Alleys are one of the classical elements of open space topography as well as in cultural landscape and city space. These historical plant forms which have survived to our times require special conservatory attention – protective and maintenance works. In this study, one method of evaluating the condition of old trees is presented. The trees are the remains of the alley layout at the former manor house in Zemborzyce. In 2015, an inventory of alley trees was carried out and the internal structures of the examined trees were evaluated using sound tomograph PICUS . The non-invasive method used is especially recommended to evaluate the health condition of valuable, old trees. It allows us to examine each tree extensively and carry out individual procedures according to conservatory rules.

Streszczenie
Do klasycznych elementów ukształtowania i wyposażenia przestrzeni otwartych, jak również krajobrazu kulturowego i przestrzeni miejskiej należą aleje. Te zabytkowe formy roślinne, które przetrwały do naszych czasów, wymagają szczególnej uwagi konserwatorskiej – prac zapobiegawczych i pielęgnacyjnych. W prezentowanej pracy przedstawiono jedną z metod oceny kondycji drzew wiekowych, które są pozostałością układu alejowego przy dawnym dworze w Zemborzycach. W roku 2015 wykonano inwentaryzację drzew alejowych i oceniono wewnętrzne struktury pni badanych drzew za pomocą tomografu dźwiękowego PICUS . Zastosowana bezinwazyjna metoda jest szczególnie polecana przy diagnozowaniu stanu zdrowotnego cennych, starych drzew. Pozwala na staranną ocenę każdego egzemplarza oraz określenie indywidualnych kryteriów postępowania zgodnie z poszanowaniem zasad konserwatorskich.

When designing a contemporary garden, be it private or public, it should be remembered that it has to be not only functional and aesthetic, but it should also have some theme and unique atmosphere – this can be achieved through, for example, artistic objects. Properly selected and placed to catch the eye, they arouse emotions and engage the intellect. Every historical epoch and all types of garden have their own distinctive sculptural themes and materials.
