Hi-tech trials boost research on native forest carbon stocks

DOC says trials collecting data on forests using helicopter-mounted hi-tech 3D lasers could have significant benefits for climate change mitigation and conservation.

Remote sensing is the science of obtaining information about objects or areas from a distance, typically from satellites, aircraft or drones. For this research, laser technology (known as LiDAR) from helicopters and light planes is used to produce high definition, 3D images of a landscape including the vegetation.

DOC has contracted Manaaki Whenua – Landcare Research scientists to do the trials. Manaaki Whenua recently established a one-hectare indigenous forest field test site in Waitutu Forest, Fiordland, working with Waitutu Incorporation and Interpine Innovation (a Rotorua-based forestry service).

This research will also help Manaaki Whenua produce maps to help researchers, landowners and businesses with the management of carbon storage and emissions in native ecosystems.
