The naturalisation of plants in urban Auckland, New Zealand 2. Records of introduction and naturalisation

Abstract

Written records, herbarium specimens and recent plant finds are used to ascribe 615 alien species to six naturalisation periods from pre-1840 to 1985. An average of one species naturalising every 88 days (4.12 per year) is being maintained. Europe, Asia, and N. Africa have contributed more than half the species. Plants introduced deliberately made up one third of the naturalised species in 1900 and now account for nearly half. One hundred and three plant families are represented.
