AbstractIn the subalpine tract of the Bogong High Plains (37°S, 147°E; altitude 1600–1800 m a.s.l.) the vegetation consists of a mosaic of snow gum(Eucalyptus pauciflora)woodland, heathland, grassland and wetland communities. Classification (polythetic‐agglomerative) and ordination (principal co‐ordinates analysis) of quadrat data from heathlands and grasslands on relatively well drained sites allowed the identification of four main heathland and grassland vegetation units. These units may be ranked in a structural and floristic continuum, from closed heath variously dominated byProstanthera cuneata, Orites lancifoliaandPhebalium squamulosumto closed heath dominated byP. squamulosumandGrevillea australis,open grassy heath ofG. australisandPoa hiemata.and grassland ofP. hiemata.The transition fromProstantheraclosed heath toPoagrassland is correlated with gradients of decreasing steepness and rockiness of terrain, and increasing exposure an
