This paper is dedicated to Voivodship Park of Culture and Recreation in Chorzów (Silesia Park) – one of the biggest of its kind in Poland and in Europe (ca. 600 ha of total area). Construction of the Park had begun in 1954 according to the design under the direction of prof. Władysław Niemirski. After many years it became an example of successful land remediation and re-naturalization of anthropogenic landscape. The whole facility though formally created in socrealism style, actually represents classical modernism’s features inspired probably by American parks with a rich recreation program.

Silesia Park in Chorzów was established on land of poor quality and partially degraded. 60 years since that event, the research have been carried out to identify both the degree of structural preservation of the Park Stand’s structure in relation to the original design goals and also the direction of any changes – due to the effects of years of land remediation and the flora’s natural succession. It was found that vegetation of Silesia Park remains, in general, consistent with its original master plan, however, after 60 years significant changes have occurred, affecting the Park’s function, its general form and landscape values.

During 2017, the authors conducted an evaluation of so-called “veteran trees” in Warsaw — selected specimens with outstanding historical, landscape and natural values, but not taken under legal protection, situated within public space (streets, squares, public facilities) — as part of a pilot program for the Green Board of Warsaw. The following were examined: the condition of trees, the surrounding ground’s condition, spatial conditions. The presented results include an example of two locations — prestigious streets, on which legible systems of street tree plantings from the beginning of the 20th century have been preserved (Piękna Street, J. Ch. Szucha Avenue). The protection of old trees — living witnesses of history and the maintenance of the original spatial form — classic avenue arrangement in both cases are essential for preservation of the historical pre-war scenery of this part of Warsaw.
