New Zealand has several notable wetlands but 90% of wetland areas have been lost following European settlement.

Contents

The Resource Management Act 1991, the major Act of Parliament determining land use, defines wetlands as "permanently or intermittently wet areas, shallow water, and land water margins that support a natural ecosystem of plants and animals that area adapted to wet conditions". The Ramsar Convention, an international conservation agreement for wetlands to which New Zealand signed up to in 1971, has a wider definition of wetland. [1]

Since the mid-19th century, New Zealand has lost about 90% of its wetland areas due to draining for farming. Many remaining wetlands are also degraded due to pollution, grazing, drainage and presence of invasive plants. In the late 20th and early 21st century, efforts have been made towards wetland conservation. [2]

Ramsar sites

The Department of Conservation currently administers seven Ramsar sites protected under the Ramsar Convention, covering an area of about 56,000 hectares (140,000 acres). [3] [4]

Other wetlands

Other notable wetlands in New Zealand include Ahukawakawa Swamp, Aramoana, the Kepler Mire, Kai Iwi Lakes, the Sinclair Wetlands, and Te Henga, as well as areas around the lower reaches of the Waikato River.

The Rakatu Wetlands in the South Island are part of an ecological restoration project set up address the environmental effects of the construction of the Manapouri Power Station.

Travis Wetland is a restoration project covering 116 hectares (290 acres) of land in urban Christchurch formerly drained and used as a dairy farm.

<span class="mw-page-title-main">Swamp</span> A forested wetland

A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundation or soil saturation. The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more formally termed a bog, fen, or muskeg. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo.

Farewell Spit is a narrow sand spit at the northern end of the Golden Bay, in the South Island of New Zealand. The spit includes around 25 kilometres (16 mi) of stable land and another 5 kilometres (3.1 mi) of mobile sand spit running eastwards from Cape Farewell, the northern-most point of the South Island. Farewell Spit is the longest sand spit in New Zealand, and is a legally protected Nature Reserve. The area is designated as a Ramsar wetland site and an East Asian–Australasian Flyway Shorebird Network site. Farewell Spit is administered by the New Zealand Department of Conservation as a seabird and wildlife reserve. Apart from a small area at the base of the spit, it is closed to the public except through organised tours.

<span class="mw-page-title-main">Environment of New Zealand</span> Overview of the environment of New Zealand

The environment of New Zealand is characterised by an endemic flora and fauna which has evolved in near isolation from the rest of the world. The main islands of New Zealand span two biomes, temperate and subtropical, complicated by large mountainous areas above the tree line. There are also numerous smaller islands which extend into the subantarctic. The prevailing weather systems bring significantly more rain to the west of the country. New Zealand's territorial waters cover a much larger area than its landmass and extend over the continental shelf and abyssal plateau in the South Pacific Ocean, Tasman Sea and Southern ocean.
