Abstract: The main protection forests lie in the Eastern and Southern half of the island. On the pumice lands west of the volcanoes forest is not continuous and it is necessary to give consideration to tussock and scrub lands outside forest proper. Vegetation types are broadly correlated with climate and soils, and evidence is given of long-term changes operating at the present day but differing on greywacke and on pumice. Superimposed changes due to man and introduced animals are extensive and are causing a general deterioration of protective cover, but there is some evidence of the adaptation of vegetation to browsing.
