Introduced Species are those plant species alien to the Northern Territory and naturalised such that they are past the first generation outside of cultivation, reproducing and establishing new individuals and populations without deliberate assistance by humans. The Northern Territory has over 470 naturalised, introduced plant species, almost 10% of the flora. While many are Declared Weeds under the Weeds Management Act 2001 and Regulations, many more are not. The Herbarium houses collections of these plants and plays an important role in providing authoritative identifications of naturalised, introduced species, in support of the Departments Weeds Division and Commonwealth Biosecurity Agencies.
