Table 1. Evaluating naturalness in the Hemeroby Indicator of Human Impact.

Degree of hemeroby Degree of naturalness Human impacet Cover type
Ahemerobic Natural/almost no human impacts None Bare rock(암석지대), Glaciers(빙하, 만년설)
Oligohemerobic Close to natural/weak human impacts Limited removal of wood, pastoralism, depiction through air and water Broad-leaved forest(활엽수림), Coniferous forest(침엽수림/PNV), Intertidal flats(조간대), Mixed forest(혼효림/PNV), Coastal lagoons(석호), Beaches, dunes, sands(해변과 모래언덕), Estuaries(하구), Inland marshes(내륙 습지), Sea and ocean(바다와 해양), Peat bogs(수렁 습지)
Mesohemerobic Semi-natural/moderate human impacts Clearing and occasional ploughing, clear cut, occasional slight fertilisation

Coniferous forest(침엽수림/not PNV), Transitional woodland –shrub(산림, 관목) Mixed forest(혼효림/not PNV), Sparsely

Vegetated areas(희박 식생지), Natural grasslands(자연 초지), Burnt areas(산불 지역), Moors and heathland(황무지 등)

β-Euhemerobic Relatively for from natural/moderate strong human impacts Application of fertilizers lime and pesticides, ditch drainage Green urban areas(도시 녹지지역), Water courses(물길), Pastures(목장), Water bodies(수역), Land principally occupied by agriculture with significant areas of natural vegetation(자연식생 발생지)
α-Euhemerobic Far form natural/strong human impacts Deep ploughing, drainage, application of pesticides and intensive fertilisation Sport and leisure facilities(스포츠 및 레저시설), Non-irrigated arable land(경지정리가 안 된 경작지), Vineyards(포도원), Complex cultivation patterns(복합 경작지), Orchard(과수원)
Polyhemerobic Strange to natural/very strong human impacts Single destruction of the biocenosis and covering of the biotope with external material at the same time Discontinuous urban fabric(불연속적 도시), Construction sites(건설사이트), Mineral extraction sites(채석장), Dump sites (쓰레기 매립지)
Metahemerobic Artificial/excessively strong human impacts Biocenosis destroyed Continuous urban fabric(연속적 도시), Port areas(항만), Airports(공항), Industrial or commercial units(상업,업무). Road and rail networks and associated land(철도)
