Mahonia (Berberis lomariifolia)

Also known as: Chinese holly

Profile

Impact

Mahonia can form dense thickets which exclude other understorey vegetation. It is unpalatable to stock. It has been assessed as a very high weed risk and the priority is to prevent its establishment as an invasive weed in north-east NSW. 

Distribution

This plant has been found in several clusters on the Dorrigo plateau near Bellingen invading canopied gullies and forests. 

Description

Mahonia has a shiny holly-like leaf, yellow flowers and green-turning-purple berries.
