"The arrival of the highly pathogenic H5N1 strain of bird flu in Aotearoa New
Zealand last month triggered a national response years in the making.
By then, surveillance systems, species protection plans and even vaccines for
some birds were already in place as part of a coordinated approach led by the
Ministry for Primary Industries.
Yet even these preparations may not be enough to save some of the country’s
rarest birds. Many survive in tiny, isolated populations with limited genetic
diversity.
For these highly vulnerable species, the outcome may depend not only on
conservation efforts, but also on chance.
Genetic diversity acts as nature’s insurance policy against disease. In large
populations, some individuals are more likely to survive an outbreak and help
the population recover.
But in small, isolated populations with little genetic diversity, those odds
are much lower, leaving species far more vulnerable to extinction."
