Enhancing biodiversity

Learn what the University is doing to care for and enhance the biodiversity of our urban and non-urban spaces, including reserves and extensive botanic collection.

Our approach

Grounds and Precinct kaitiakitanga practice 

The Grounds and Precinct team's kaitiakitanga practice is founded on minimising external inputs to create a sustainable biodiverse ecosystem.

A sanctuary for bees sits next to the nursery where seedlings are propagated, no pesticides or herbicides are used and, as the trees reach the end of their lifespan, there is an extensive mulching programme to reduce water use, suppress weeds and improve the soil. Any salvageable wood is turned into garden seating.

Our urban environment

Sector 100 gardens

The university’s historic sector 100 gardens include over 400 trees and shrubs. A master survey sheet records each tree’s key attributes including common and botanical name, height, girth, crown spread, general condition, age, protection status, location and whether there is any management work required.

Current management work practices of the gardens surrounding the collection include choosing plants that support birdlife, insects’ life such as bees and butterflies, composting garden debris, extensive mulching, chipping all branches to place them back into the garden, controlling moisture levels and soil temperature as well as limiting pesticides and herbicides.

University of Auckland city campus biota

In 2018, Associate Professor of Biological Sciences, Bruce Burns, set up a project with a local crowd-sourcing website to help investigate the University of Auckland city campus biota. The project now has over 2700 observations representing more than 1,100 species including Protozoans, Fungi, Plants, Chromista, Mollusks, Insects, Arachnids, Reptiles, Mammals, Amphibians, and Birds.

Native bee colony

The ngaro huruhuru, native bee colony have been dwelling on the turf covered earth bank, at the rear of Old Government House where the hatching of two species of bees took place in early November 2021. Their nest site is protected by punga fern logs securing the turf bank. The Three Kings Titoki, Alectryon excelsus var. grandis is their favoured source of pollen and nectar, which is gathered from the mature male flowers.

Scientific reserves and conservation areas

The University has cared for scientific reserves and conservation areas for many decades, there are currently six reserves under its management. These are in Anawhata, Ardmore, Huapai, Oratia, Swanson, and Leigh. In addition, the University was gifted land on Waiheke Island (Goldie’s Estate) which includes a wetland surrounded by restored native vegetation.

The University Reserves Advisory Group is responsible for managing the University's reserves.
