Native Trees and Shrubs of Marlborough
Marlborough's diverse geography and climate supports a variety of native trees and shrubs, some found only within the region, while there are also local examples of many species found throughout New Zealand. Prior to the arrival of humans, most of Marlborough was forested, however with the arrival of the first humans from Polynesia, areas of forest in the east were burnt, and on the later arrival of Europeans, extensive forest clearing occured in many areas that remained forested.
Mixed beech and podocarp forest are found in wetter parts of the Marlborough Sounds, undisturbed parts of the Pelorus valley, and the Richmond Range. In the upper Wairau and some of its tributaries, there are areas of beech forest. In south east Marlborough dry shrubland is the main form of native vegetation. Coastal forest with a variety of species can be found in parts of the Sounds and on some islands.
A number of shrubs are unique to Marlborough, including several native broom species, and Marlborough is the natural southern limit of a number of species found elsewhere in New Zealand.
