This tiny animal, measuring just 1. The last 40 years has seen a rapid decline in their numbers. In the s their population sat at around 29, Today, this has shrunk to around 15, Females only start breeding between the age of 7 to 9 and will have one calf every years.
The small number of animals can also lead to a genetic bottleneck which leaves these dolphins susceptible to diseases, birth deformities and higher mortality rates. Disease outbreaks of Brucellosis and Toxoplasmosis are an additional, potential problem for this vulnerable population.
Notwithstanding the accelerated and worrying loss of these creatures, insufficient protective measures are in place to help their recovery. Despite calls from scientists, conservationists and the general public to create a larger exclusion zone for these dolphins, large areas of habitat are still exposed to various threats.
The New Zealand governmen t has banned the use of set netting in some areas, but has resisted measures to further increase the protective zone for these dolphins claiming that they are not found in the areas where there is a supposed threat. It is predicted with the current decline in the Maui population, that they could be extinct within the next 15 years.
Immersed in the most incredible scenery and wildlife experiences, she consequently has a wealth of photos and stories from her time in these places.

Webster, T. Your help could be crucial to stopping their extinction. Ordinary Kiwis like you have power. The previous abudance estimate was 55, but as the confidence intervals for each estimate overlap, this does not mean the population has stablised or increased. It is very unlikely that more than 10 calves exist at any given time with a population level this low. It also means there needs to be about 20 mature adult females over 7 years of age for the population to recover.
