Summary of case study

The Auckland Botanical Garden acts as an ecosystem protection programme for many collections of plants that are both introduced and native to the area. Its main initiative has been to develop sustainable horticultural principles (Auckland Botanical Gardens, 2023). The aim is to establish plants that require minimal maintenance. To achieve this, plant trials and research can determine which plants perform well and remain healthy in relation to Auckland’s climate, especially as the climate changes. This research in the gardens is the basis for many planting-related initiatives around Auckland once successful. This research also enables climate change adaptation by establishing plants best suited for changing temperatures.

The Auckland Botanical Garden’s development in both size and green infrastructure potential over the years also helps with climate change mitigation. Adding urban greening systems like botanical gardens within the urban framework allows for climate benefits such as reduced air pollution, carbon storage, and water pollution mitigation by reducing stormwater runoff (Cavender & Donnelly, 2019).

The Auckland Botanical Garden attracts more than 950,000 visitors each year which not only benefits people’s health and well-being but also contributes to the economic recreation and tourism sector. Being a landmark of ecology has added many benefits to local people including the opportunity to get involved in volunteer initiatives.

Within the garden, there are 10 hectares dedicated to native forest which contributes to the preservation of Indigenous toanga species (special ‘treasure’ species). This also helps towards creating a sanctuary for native wildlife and protection of native plant species.

Being a non-profit initiative, The Auckland Botanical Garden can be maintained by volunteers which allows for education and social connections adding to the value of the project.
