The kahikatea (Dacrycarpus dacrydioides) forest of South Westland.
Dacrycarpus dacrydioides forests in South Westland between the Waitangitaona and Saltwater rivers occur on low terraces of alluvial silt. Their relationship to other river flat and swamp communities on post-glacial surfaces is described. Recently abandoned river beds are colonised by pioneer species, which give way to vegetation dominated by grasses, sedges and rushes, which in turn are invaded by woody plants, especially Coprosma propinqua and Podocarpus totara var. waihoensis.
