 A study published in the South African Journal of Botany found the species to be a potential risk of becoming an invasive species along the coasts of South Africa.It suggested a number of different ways to prevent the spreading of the species in the wild, one of which included barring the cultivation of the species outside of an unsupervised area.Additionally, however, the study pointed out that "E. aureum" cannot propagate on a large scale due to its lack of seed banks as well as its minimal immunity to herbicides.
