20210427 09203400 1.0 TRUE Gamba grass Native to Africa's tropical and subtropical savannas, Gamba grass is a perennial tussock grass introduced to many parts of the world for use as an improved pasture plant. Gamba grass was imported into Queensland as a pasture grass in 1942, but was not planted on a large scale until about 1983. Gamba grass is a useful cattle feed in parts of far north Queensland, but also has significant negative impacts, including replacing native plants and increasing fire risk. © State of Queensland (Department of Agriculture and Fisheries), 2023 weeds pests Map layer extracted from Biosecurity Queensland pest distribution survey displaying distribution of individual invasive weed species.
