National Government presiding over the extinction of the Maui dolphin? I hope not...

Why are they so special?
The dolphin is listed internationally as 'critically endangered', which means there is a high risk of it becoming extinct in the near future.
In 2012 a DOC-commissioned study estimated the Maui's dolphin population to consist of 55 with a 95% confidence interval of between 48 to 69. The estimate is for individuals aged more than 1 year (i.e. this excludes calves of under a year).
This small population of dolphins is thought to have been isolated from their more-numerous relatives, South Island Hector's dolphin, for thousands of years.
Maui's dolphin used to be known as North Island Hector's dolphin. But research showed the North and South Island dolphins are separate sub-species that are physically and genetically distinct from each other.
This is not the first time I have posted here this year about the falling numbers of the Maui dolphins.. The previous figures I received were about 100 Maui dolphins. The Department of Conservation has expressed its concern to the New Zealand Government about the falling numbers. Even the larger Hectors dolphins need to be regularly monitored as well. Once they have gone, they are gone for ever!
