The Australian Botanic Garden Mount Annan is a regionally important haven for native wildlife. Managing the native woodlands, grasslands and open space areas is essential to maintain habitat and support healthy fauna populations.
The garden includes some fine examples of the critically endangered Cumberland Plain Woodland, which are under threat from the highly invasive African Olive tree, which can shade out native plants and eventually dominate the woodland. Research into African Olive ecology and control over the past 10 years at ABG, has led to highly successful control measures. Research is now focused on techniques to restore the original woodland vegetation in areas that have been cleared of olive forest.
