Camphor Laurel
Cinnamomum camphora
Camphor Laurel is a large evergreen tree that was introduced to Australia as an ornamental and for timber production. It has become a major environmental weed, particularly in subtropical regions, where it dominates rainforest margins and displaces native vegetation through allelopathic effects.
How to Identify
- Large tree up to 20-30 metres tall with dense, spreading canopy
- Smooth grey bark becoming rough and fissured with age
- Glossy, oval leaves with three prominent veins
- Strong camphor smell when leaves are crushed
- Small cream/yellow flowers in spring
- Round black berries about 1cm diameter
Where It Grows
Invades disturbed and undisturbed rainforest, wet sclerophyll forest, and riparian zones. Common along creeks, gullies, and anywhere birds disperse seeds.
Environmental Impact
- Allelopathic chemicals suppress native seedling growth
- Dense shade prevents regeneration of native rainforest
- Berries are spread widely by birds
- Shallow root system can contribute to erosion
- Large trees difficult and expensive to remove
Control Methods
- Cut stump treatment with herbicide most effective
- Stem injection for large trees
- Ring-barking can be effective but slow
- Forestry mulching for multiple trees
- Must treat all regrowth promptly
- Replanting with native species recommended after removal
Seasonal Activity
Flowers in spring, fruits in autumn. Can drop leaves during dry periods.
