Abstract The aims of the study were: (i) to examine how well hillock forests are distinguishable from comparable site types, (ii) ascertain forest indicator species, (iii) elucidate forests’ community (iv) assess practical requirement for differentiation as a self-sufficient typological unit forestry. data included altogether 160 descriptions communities and 42 relevés other type stands comparison. historical continuity was estimated old topographic maps. We established that constitute statistically reliable distinct group forests. Among characteristic species having an value significance level up 0.50, by ecological strategy 43.2% belong competitors, 37.8% competitors stress-tolerant ruderals, 10.8% stress tolerators; according hemeroby, 62.5% these apophyts 30.0% hemeradiaphors. Most (55.6%) located on former slash-and-burn areas (bushlands) or reforested agricultural land (36.1%). can be classified into four types: 1) Fragaria vesca–Festuca ovina–Pinus sylvestris type, 2) vesca–Oxalis acetosella–Pinus 3) vesca–Viola mirabilis–Picea abies–Populus tremula and, 4) vesca–Equisetum pratense–Betula pendula type. There is no need define separate in typology, nevertheless recognition representing habitat directive 9060 important viewpoint biodiversity maintenance.
