The Effects of Exotic Animals on an Area of Native Vegetation in the Tararuas

Abstract

Lying isolated from neighbouring land masses, New Zealand offers conditions for plant life different from those in most other regions. The area, greater than most oceanic islands, allowed the development of a rich vegetation made up of many species. Added to this the variety of conditions produced by altitudinal effects and the different climatic conditions due to the fact that the main islands lie on a longitudinal axis rather than latitudinal have been sufficient to develop a variety of indigenous elements.
