Forest Succession on landslides above Lake Thomson, Fiordland

Abstract
Forest succession following Ianilsliiles is described from an altitude of about 1,000 ft on a steep northerly slope above Lake Thomson, west of Lake Te Anau, in Fiordland. Two distinct serai patterns are described from six adjacent stands, ranging in age from 15 years to mature forest. On the denuded slip-faces the relatively drought tolerant Leptospermum scoparium is the principal seral species. On the detritus of the debris-fans, almost pure stands of Aristotelia serrata, followed by Fuchsia excorticata and possibly by Hoberia glabrata, intervene before the return of the climax forest dominated by Nothofagus menziesii. For each of the six stands, the structure and composition of the vegetation and a brief description of the soil is presented.
