Invasive non-native flora and fauna species identified in marine ecosystems
Queensland has two species of invasive non-native marine flora and fauna species (marine pests) established with a high possibility of further introductions through international shipping activity and other pathways.
Invasive non-native marine flora and fauna species (marine pests) can cause damage to the marine environment by killing native plants and animals, outcompeting them for space and food, and altering habitats. Eradication of a marine pest once established is rarely effective: prevention and early detection are the key strategies to minimise marine pest threats.
White colonial sea squirt and Black scar oysters have recently been detected in Queensland and are considered established in number of locations. Asian green mussels have been detected on a number of occasions over the past few years on vessels and also a small number of environmental detections (on a marine pest detection settlement device and a washed-up log) however rapid response to the detections, including surveillance activities, indicate no known establishment.
