Invasive & problem species identification and assessment

We undertake risk assessment studies of potential introductions of alien species in freshwater and marine environments, and we undertake surveys of marine alien species in ports and bays, ballast water surveys, assess hull fouling problems.  We also assess the socio-economic implications of invasive and problem species in both aquatic and terrestrial habitats and advise on policy and approaches to deal with them.
