Summary of case study

Auckland’s Urban Ngāhere (Forest) Strategy for renaturing the city recognises the social, environmental, economic, and cultural benefits that the urban forest can give. The driving goal for the strategy is to reach a 30% canopy cover over Auckland’s urban area and around 15% in each local board area (Auckland Council, 2019). This framework has been developed in relation to issues including urban population growth, rising inequality, impacts from invasive pests, and climate change (Auckland Council, 2019). 

Adding more green infrastructure to the urban network has enabled climate change adaptation by ensuring a more absorbent city for water and carbon emissions. With increased storm intensities, increased canopy cover ensures a more absorbent structure and areas for water to flow into during extreme weather events.

Through the Auckland Urban Ngāhere strategy, social benefits have been outlined and include improved health and well-being, reduction of the urban heat island effect, increased tree shading and enhanced visual amenities (Auckland Council, 2019). 

The established planting prior to this project represents a part of Auckland’s cultural heritage. Native planting once was used as a traditional supermarket, learning centre, medicine cabinet, school, and spiritual domain (Auckland City Council, 2019). Trees also represented landing places for waka and birth whenua (Auckland City Council, 2019).
