Juvenility and Maturity of Woody Species in New Zealand
Millions of years ago, so it has been argued, New Zealand was once part of a great southern continent, Gondwanaland, in close contact with Australia and Antarctica and so linked through to South America.1 The animal and plant species that evolved on this continent were inherited by New Zealand. During the Jurassic period (190 million years ago) in the age of the gymnosperms New Zealand acquired the ancestral podocarps. Later, in the Cretaceous period (120 million years ago) the newly developed angiosperms were received, the Magnolia, Protea and Fushia families, but predominantly the Fagaceae. At this time amphibians and reptiles roamed the land and the first birds were evolving.
