On 970 ha of the monitored area of Hodonínská Dúbrava, which includes the Hodonínská Dúbrava National Natural Monument, a field survey was carried out in the form of monitoring of wild boar (Sus scrofa) rooting in order to clarify the extent of the wild boar's impact on the forest ecosystem. The subject of the investigation were fresh wild boar rootings, therefore the monitoring was carried conducted after winter, in the spring of 2022. It was necessary to follow established lines evenly distributed over the area and each recorded fresh rooting was documented in the GPS device as well as in a spreadsheet. A total of 2,298 recordings were collected with detailed information on the rooting area, layer or for example vegetation cover. These data were supplemented with LHP data from the Forests of the Czech Republic followed by their evaluation. Wild boar largely preferred medium-aged pine stands and mature oak stands and its activities mainly affected forest types 1S and 1O. In majority of cases, the wild boar rooted to a depth of 25 cm and preferred the soil subtype Cambysem arenaceous. Distance from roads and watercourses became a significant factor in the intensity of rooting.
