Checking on tree health

An aerial view of an infected kauri tree in Waipoua forest

The Northland Regional Council begins an aerial survey of the Pouto Peninsula and other areas this month, seeking data on the overall health of Northland forests. It also identifies dead or dying kauri trees to help manage and prevent the spread of the dieback disease.

“Identifying where kauri dieback is in Northland will ensure landowners, tangata whenua and agencies, can better manage the disease and stop it spreading further in Northland,” said NRC biosecurity manager, Kane McElrea. “This information then informs decisions such as which tracks should be upgraded first, or which activity groups need to be worked with and educated, in order to reduce the risk of the disease being spread.

“Aerial surveillance is carried out with an aircraft flying in a grid pattern, while high definition stills cameras record every unit of ground.

After the flights are made, any stands of kauri that look as though they are diseased are visited by ground crews, for further assessment and likely soil tests.”
