The vegetation of Mt Karioi, North Island, New Zealand

Abstract

The indigenous forest on Mt Karioi was surveyed in 1974-75 and the data examined using multivariate techniques. These revealed a number of recognisable communities. Altitude and aspect were the main environmental factors determining plant distribution. An abrupt change in Iloristic composition at about 550 m elevation was attributed to fog. The regeneration of many tree species was threatened by a high population of goats. Some floristic differences were also noted between Mt Karioi and other mountains in the Waikato region.
