The dominance, diversity and activity density of rove beetles were studied in Central European apple and pear orchards. Altogether 6 877 individuals, belonging to 271 species and 11 subfamilies were collected. Thirteen species presented a relative abundance from 9 to 2% and amounted to almost 56% of all staphylinids recorded. In dominance order they were: Dinaraea angustula (Gyllenhal), Omalium caesum Gravenhorst, Drusilla canaliculata (F.), Sphenoma abdominale Mannerheim, Palporus nitidulus (F.), Xantholinus linearis (Olivier), Dexiogya corticina (Erichson), Coprochara bipustulata L., Mocyta orbata (Erichson), Oligota pumilio Kiessenwetter, Xanthlinus longiventris (Olivier), Tachyporus hypnorum (F.) and Pycnota vicina (Kraatz). The alpha diversity of staphylinids for different environmental conditions was relatively similar but the Shannon-Weiner Index (H`) was higher than of other similar studies. However, the activity density was higher in pear, in sand and in abandoned plantations; under different environmental conditions this could not be considered uniform in time. After the cumulative studies on the population dynamics, one can conclude that the highest number of species can be found in spring and in summer. Species D. canaliculata and P. nitidulus presented the similar seasonal dynamics in orchards located in different environmental areas, while O. caesum had the same activity density both in apple and pear orchards.
Fruit tree orchards were present in some public parks from the very beginning of their existence in the 19th century. Apart from the utilitarian role, in the 20th and 21st centuries, they also gained different ones: ornamental — on account of high aesthetic qualities of fruit trees in the flowering and fruit-bearing seasons, environmental and ecological — related to supporting biodiversity, cultural — in the context of memory of old forms of using rural and allotment gardens, social — as a space for leisure, and even therapeutic — as an element of hortitherapy. The growing popularity of orchards indicates a change in the trends in contemporary public parks development.
