Miners had agreed to revegetate the area which they did with the noxious pest bitou bush (Chrysanthemoides monilifera), which the various land care groups are now trying to eradicate.
Invasive weeds which compete with the plant for resources include bridal creeper (Asparagus asparagoides), bitou bush (Chrysanthemoides monilifera), blackberry (Rubus fruticosus agg.), St John's wort (Hypericum perforatum), kikuyu (Pennisetum clandestinum), lantana (Lantana camara), African olive (Olea africana subsp. africana) and privet (Ligustrum lucidum).
However when looked at closely there is a bigger threat to the Brittle Greenhood than animals and that is other plants, specifically the Chrysanthemoides monilifera, or Boneseed weed.
