technique often seen in crime TV shows will be used to hunt for biodiversity in Wanaka.

The Wanaka Bioblitz will use a transect line — a row of searchers — to uncover all forms of life at Eely Point.

Co-ordinator Ash Rabel said the aim was to find and record ‘‘anything alive that you can see’’.

‘‘The plan is to encourage everybody to get out and have a look at nature around them.’’

People would be asked to use their phones to take pictures of all they saw.

‘‘It’s amazing just how much biodiversity there is just in backyards.’’

An app called iNaturalist would be used to record and find information.

‘‘So you take photos of organisms that you see, it could be plants, bugs, birds, anything.’’

The app was able to automatically identify some items, and there was also a network of experts who could look at what was recorded in the app and give more information.

The ground would be divided into grids, to allow for focused attention of what existed in the area, and GPS co-ordinates were recorded allowing for very specific data-gathering.

A transect line was like scenes from murder mystery shows where a line of people would search for clues across a field.

However, in this case it would be a way to narrow down and focus on what could be seen in nature.

The organisers were not going to be strict about it because they wanted to open up the day to everybody, but it was a way to show how scientists went about collecting data, Mr Rabel said.

Experts would also be on-site to help explain what people found, and searchers did not need to stay for the whole time, they could come when it suited.

The aim was to be inclusive, so people could also record what they found in the style that suited them, including drawing items, Mr Rabel said.

‘‘Hopefully, we can find something really neat, something endangered or something we didn’t expect to see here.’’

– The Wanaka Bioblitz takes place Sunday November 1 from 10am to 3pm, starting at Bremner Bay car park by Eely Point.
