20210427 09203100 1.0 TRUE Non-indigenous acacia: Umbrella thorn <DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN><SPAN>Native to most of Africa and Arabia, umbrella thorn is a medium to large, canopied tree that can grow to 21m. The stems have a combination of paired straight and paired hooked thorns. It has the potential to become a major weed in Queensland due to its long seed viability and ability to tolerate drought, wind, and salinity; and it can grow in a wide range of soil types. A single tree was detected by the roadside at the Port of Brisbane in 2019 and removed. Umbrella thorn is a prohibited plant in Queensland.</SPAN></SPAN></P></DIV> © 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.
