Nothofagus truncata (Hard Beech) in the Upper Taramakau Catchment, South Island, New Zealand

Scattered small stands of Nothofagus truncata occur in the upper Taramakau catchment, Arthur's Pass National Park, beyond the previously assumed range of the species in north Westland. Restricted to older soils on stable north to north-west slopes, the N. truncata stands are surrounded by N. fusca dominated forest and their upper altitudinal limits at 370-500 m border N.fusca-N. menziesii or N. solandri: var. cliffortioides forest.
