Nature fans in New Zealand cities are getting ready to showcase our incredible urban biodiversity to the world by
joining in the 2022 global bioblitz City Nature Challenge.
From Friday 29 April to 2 May 2022, keen nature watchers in New Zealand cities and regions will join tens of thousands
of people across the globe to look for nature in their backyards and cities, and record their observations using the
free mobile app iNaturalist.
Seven New Zealand cities and regions are registered to participate in the challenge: Auckland, Hamilton, Hawke’s Bay,
New Plymouth, Wellington, Christchurch, and Invercargill. Any resident or visitor in those areas can participate, and
the challenge is to gather the most observations of nature, find the most species, and engage the most people in the
event.
Ecologist and NZ iNaturalist Trust chair Colin Meurk says the four day event will be the biggest, coordinated
country-wide bioblitz, and we expect to discover many unexpected creatures and organisms – both good and bad.
“People are surprised, when they start looking, by just how much nature there is in the urban environment, thinking they
have to go out into the countryside, the mountains, or bush to find anything interesting. But all our cities are at the
nexus of our richest and most threatened lowland and coastal habitats.”
The iNaturalist app uses the power of everyday people to map and catalogue the world’s biodiversity, while creating a
fabulous resource for science and research. “Through the iNaturalist NZ—Mātaki Taiao community we’ve discovered new
species, found plants and insects in unexpected places, and spotted invasive pests and diseases,” says Dr Meurk.
People can start in their own backyard and don’t need to know what they are photographing because once the photos are
uploaded, scientists can scan through the pictures and verify the AI identifications or propose alternatives. This can
lead to important discoveries such as the first myrtle rust case spotted in Christchurch in May 2021.
The City Nature Challenge is the perfect activity for the last week of the school holidays. Find out more and join in at https://inaturalist.nz/projects/city-nature-challenge-2022-aotearoa-new-zealand
