A Class 1 declared plant, honey locust, Gleditsia spp., has been located in the North Burnett region near Mundubbera. The notifiable pest was located on the banks of the Auburn River and is now being treated and monitored.
Honey locust is a fast growing invasive tree and is considered a serious pest due to its invasiveness and environmental, economic and social impacts.
It is a deciduous, leguminous tree growing to 20 metres tall. It has creamy yellow hanging flower stalks (10 cm long) that develop into a 20-30 cm long brown pods. The plant seeds prolifically every 1-2 years and the pods are spread by cattle. The trunk and limbs of some varieties bear very large crucifix-like spines that can grow to more than 50mm. There are many ornamental thornless varieties of honey locust; these varieties are still a declared class one plant.
Honey locust was originally introduced from North America and planted in Queensland in 1907 as a fodder and ornamental tree. Honey locust can grow in most soil types but prefers alluvial flood plains along river systems.
Honey locust has been found in the North Burnett region before in the Monto area but the plants have been controlled and the area monitored. The area has been inspected and the newly found infestation is currently being treated. At this stage only the one clump of honey locust has been found on the Auburn River.
