Tree Council survey shows tree canopy dwindling in Auckland

A high-tech environmental survey in Auckland has revealed the urban tree canopy is dwindling. The Tree Council survey used LiDAR - laser technology that can produce a three-dimensional image of topography - to measure the abundance, species and height of city trees. Tree Council secretary Dr Mels Barten presented the survey results to Auckland councillors yesterday. She told the environment committee it's crucial they protect the ngahere and there are few mature trees left in the city.
