Upper Waitaki zone biodiversity

Wide open basins are set against a backdrop of the highest mountain peaks in the country, forming a striking contrast in a dramatic landscape packed with unusual features.

Highlights

There are many nationally rare and threatened ecosystems found in the zone, including inland alluvial surfaces, inland dune systems, ephemeral wetlands (kettleholes), and braided rivers.

Threatened native fish species include: lowland longjaw galaxias, big nose galaxias, upland longjaw galaxias, longfin eel and koaro.

37 native wetland/river birds are found in the Upper Waitaki, with 20 of those species listed as threatened. The six most threatened species are grey duck, white heron, black stilt (all nationally critical), followed by bittern, black-fronted tern and black-billed gull (nationally endangered). 16 native terrestrial bird species, including five threatened species, have been identified in the Upper Waitaki zone. Those threatened species are: eastern falcon, rockwren, South Island rifleman, kea and long-tailed cuckoo.

Many threatened invertebrate species have been identified in the Upper Waitaki Zone. The Canterbury knobbled weevil was thought to be extinct, but was rediscovered recently in the Burkes Pass area.

Taking action

Immediate Steps

As part of the Canterbury Water Management Strategy (CWMS), the Upper Waitaki Zone Committee has funding of $100,000 per year for four years (2011-2015) to support projects through the Immediate Steps biodiversity protection and restoration programme. 

Funding is available to support on the ground actions which improve the ecosystem health of springs, wetlands and streams within the focus areas, such as fencing-out springs, weed control in wetlands or planting to improve in-stream habitat for mahinga kai species.
