Australia has had a problem with European rabbits since their introduction to the continent in the late 19th century. Among the plants were Prickly Pear and Spanish Reed. This time of intense disturbance to the Aboriginal way of life led to a drastic decline in both the traditional knowledge of land management and the ability of Aboriginal peoples to carry out their land management practices.
