Canterbury Region - Environment

Environment

Like much of the Canterbury-Otago tussock grasslands the Canterbury Plains have been highly modified since human settlement and now support a large agricultural industry. Prior to the arrival of Māori settlers in the 13th century, much of the modern Canterbury region was covered in scrub and beech forests. Forest fires destroyed much of the original forest cover which was succeeded by tussock grassland. By the 19th century, only ten percent of this forest cover remained and the European settlers introduced several new exotic grass, lupin, pine and macrocarpa that gradually supplanted the native vegetation. Much of the native vegetation was isolated to the alpine zones and Banks Peninsula. Recently, the amount of forest on Banks Peninsula has increased from a minimum of about one percent of its original forest cover.

The amount of dairy farming is increasing with a corresponding increase in demand for water. Water use is now becoming a contentious issue in Canterbury. Lowland rivers and streams are generally polluted and some of the aquifers are being overdrawn. The Central Plains Water scheme is a proposal for water storage that has attracted much controversy. The Canterbury Water Management Strategy is one of the many means being used to address the water issue.

The Canterbury mudfish (kowaro) is an endangered species that is monitored by the Department of Conservation.
