Extinction warning as dolphin population hits record low - WWF



Posted on 13 March 2012  | 
Maui’s dolphins could soon suffer the same fate as our extinct moa unless urgent action is taken by the Government and fishing industry “to get nets out of the water”, warns WWF-New Zealand.

A new official population estimate for Maui’s dolphins, released today by the Department of Conservation, reveals there are likely to be just 55 adult dolphins left (1).

The revised count, based on sampling done by DNA profiling, indicates the population has declined significantly since the last population estimate of 111 which was published in 2005.

“The Maui’s population has been declining since the 1970s, and protection measures introduced in 2008 have not succeeded in turning the situation around. It is a national tragedy that our critically endangered dolphins are still dying needlessly in fishing nets. We need to act immediately to get nets out of the water, including harbours and estuaries, to protect these dolphins throughout their range,” says Rebecca Bird, WWF’s Marine Programme Manager.

Conservation Minister Kate Wilkinson and Primary Industries Minister David Carter said in a statement released today that they are proposing added protection measures while a full review is done and that the Government has asked for a planned review of the Hectors and Maui’s Threat Management Plan to be brought forward from 2013 to this year (2).

Chris Howe, Executive Director of WWF-New Zealand, said in response to the Ministers’ statement, “We need to see the details of what is being proposed by the Government before we can comment on the specifics, although what is clear is that we need more extensive protection measures introduced throughout Maui’s historic range if we are to stop more dolphins dying. With a population this low, every individual is critical to the species’ survival.”

Maui’s dolphins are an in-shore species found only on the west coast of the North Island, and their current range extends from Taranaki to Dargaville. They are a subspecies of the South Island Hector’s dolphin; they share the same small size and distinctive rounded dorsal fins but are genetically distinct.

WWF is calling on the Government to ban set net fishing throughout Hector’s and Maui’s dolphins’ habitat, to prevent more dolphins dying needlessly in nets. The global conservation organisation is also campaigning for a government-led effective action plan for the recovery of these dolphins that identifies, manages and mitigates all other threats to the species, such as boat strike, pollution, coastal development, sand-mining and exploration for oil and gas.

Just last month, the then Ministry of Agriculture and Forestry (MAF) reported the death of a Maui’s in a fishing net off the coast of Taranaki. WWF is encouraging all members of the public to report any sightings of a Maui’s to its dedicated hotline, 0800 4 MAUIS, to help scientists monitor the range and movements of these small and increasing rare dolphins.

Ms Bird says, “We can’t change our past to bring back species like the moa that are lost forever, but we must not, and will not, give up on our critically endangered dolphins. We know that solutions exist to save Maui’s, it is time the government acted on behalf of all New Zealanders to protect this precious national treasure. The world is watching.”

The new population estimate released by the Govt in 2012 shows there is likely to be just 55 adult Maui's left. WWF has warned the species will soon be extinct like the moa if we don't get nets out of the water throughout the dolphins' range.
