Attempts were made to control the spread by burning, but this only exacerbated the problem as it encouraged seed dispersal while failing to kill the trees. The spread of "Melaleuca" is now managed by a combination of regular herbicide treatment and the introduction of an Australian beetle as a biological control. A number of "Acacia" species have become serious environmental pests after being introduced into southern Africa. The most troublesome species are "Acacia cyclops" and "Acacia saligna". Both are Western Australian
