Weed Potential 
As a weed Holly is invasive in regions with a cool moist climate appearing in habitats including woodlands, forest margins or along cool rainforest gullies. The lower branches can self-layer forming thickets that reduce light inhibiting the regeneration of native tree or shrub seedlings and understorey plants. 

It prefers an open sunny position on moist fertile soils and suckers from the base if the upper foliage is damaged. Female plants produce fruit from autumn to winter and germinate during spring. The seeds are dispersed by birds or animals and the plant self-layers. 

Control methods include physically digging out seedlings and small plants when the soil is moist ensuring that the roots are removed as the slender trunks snap off easily and the plant re-shoots from the base. 

Fruiting branches should be bagged and destroyed. Plants can be cut and painted on the stems or drilled and injected in the trunk towards the base with a non-selective herbicide during the growing period. Follow up applications may be requires as the shrub can re-shoots.
