Discaria toumatou



Matagouri is a native shrub or small tree that is endemic to New Zealand. It is a hardy and spiny plant that typically grows in dry, rocky, and exposed habitats. Matagouri has a distinctive appearance with tangled, wiry branches covered in small, sharp thorns. The leaves are small, dark green, and often inconspicuous among the thorny branches.


Matagouri can be found throughout New Zealand, particularly in the drier regions of the South Island. It is well-adapted to harsh and challenging environments such as riverbeds, rocky hillsides, and coastal areas. Matagouri is often found in lowland and montane shrublands and is known for its ability to thrive in poor soil conditions.

Cultural Importance

Matagouri has cultural significance to Māori, who have traditionally used the plant for various purposes. The branches were used for making fences, hedges, and traps. The thorny nature of matagouri provided effective protection and deterrence. Māori also used the plant medicinally for treating ailments such as skin conditions and joint pain.

Ecological Role

Matagouri plays an important ecological role in providing habitat and food sources for various native bird species, including silvereyes and bellbirds. The dense, spiny branches offer protection from predators and nesting sites for birds. Matagouri also helps stabilise the soil and prevent erosion in exposed and fragile environments.

Associated Birds

Bellbird: Bellbirds are known to feed on the nectar of various flowering plants, including native shrubs like Matagouri. They are often attracted to the sweet-smelling flowers and are important pollinators.

Tui: Tui are another nectar-feeding bird that may visit Matagouri shrubs when they are in bloom. They have a distinctive call and are known for their beautiful plumage, which can vary depending on the region.

Silvereye: Silvereyes are small, insectivorous birds that may be seen flitting around Matagouri shrubs in search of insects and spiders. They also feed on fruit and nectar, making them potential visitors to flowering Matagouri plants.

Fantail: Fantails are known for their acrobatic flight and their habit of following and catching insects. They may be found near Matagouri shrubs, where they could find insects to feed on.

Conservation Status

Matagouri is not currently considered a threatened species. However, its distribution and abundance can be influenced by land-use changes, habitat degradation, and invasive species. Conservation efforts aim to protect and restore the natural habitats where matagouri occurs, ensuring the survival of this unique native plant.
