Agricultural and economic impact
Bitou bush is an aggressive environmental weed in coastal vegetation. It primarily invades sand dunes, heathlands and nearby forests; it invades undisturbed as well as disturbed areas. Bitou bush can outcompete and in many cases totally replace native flora and drastically alter the environment for many native birds and animals. It can also create a favourable environment for other highly invasive weeds.
