BITOU BUSH

Bitou bush (Chrysanthemoides monilifera subsp. rotundata) is a spreading woody shrub with succulent stems, often prostrate on the ground. It primarily invades coastal dune systems. This plant is a Weed of National Significance. Bitou bush affects native plants mainly through competition, its high growth rate and, possibly, by releasing chemical inhibitors. Dense stands of bitou bush exclude other indigenous plants leading to decreasing floral biodiversity and, consequently, changes in faunal diversity. Stands of bitou bush also reduce the aesthetic appeal of natural environments and reduce recreational access to beaches and along walking trails.
Bitou bush is native to coastal regions of South Africa and has invaded coastal habitats in south-eastern Queensland, NSW and Lord Howe Island. The total area infested is estimated currently to be over 70 000 ha in Australia.

Bitou Bush is an aggressive weed in coastal dune vegetation where it can out-compete, and in many cases totally eliminate, the native flora. The invasive success of Bitou Bush is due to its vigorous growth and prolific seed production. Bitou Bush grows faster than many native plants and is free of pests and diseases giving it a competitive advantage over natives. It forms a dense green thicket which can prevent native seedlings from growing. When it forms such dense stands, it can destroy, or drastically alter, the habitat of many native birds and animals as well (Winkler et al. 2008).

Bitou Bush is naturalised in New South Wales and to a small extent in Queensland and Victoria. It is mainly restricted to coastal ecosystems with summer rainfall, similar to its range in South Africa.
