Weeds in The Park
The most significant introduced species are Giant Parramatta grass (Sporobolus fertilis), lantana (Lantana camara), prickly pear (Opuntia), blue heliotrope and blackberry. Lantana was widely distributed in warmer lower areas of the park and also invaded rainforest thickets, where it has affected World Heritage values. Burrs of the Xanthium spp. are found on river flats, banks and associated tributaries.
Blackberry, giant Parramatta grass, Lantana and sweet briar (Rosa rubiginosa) being controlled using herbicide. Spraying results have been encouraging but follow-up spraying is imperative to ensure long-term effectiveness. The release of the cactus moth Cactoblastis cactorum within the park has facilitated the biological control of prickly pear.

back ...”
