The dataset contains forest inventory data from four censuses (1999, 2007, 2013, 2023) at a single 27.624 ha plot in a beech-dominated forest that has been unmanaged since 1965 at Hainich National Park. The location and diameter at breast height (dbh) of all living trees with a dbh >= 1 cm was measured.
