Biosecurity matters

3.2.1 Flora A weed is defined as any plant that requires some form of action to reduce its harmful effects on the economy, the environment, human health and amenity (Natural Resource Management Ministerial Council, 2006). Weed species considered to be of greatest threat to natural and economic values on a national basis have been ranked as Weeds of National Significance (WoNS) (Thorp and Lynch 1999). At a State level, the Biosecurity Act 2014 identifies those weed species that represent a threat to primary industries, natural resources and the environment. Under the Biosecurity Act, a weed species can be declared as a Prohibited or Restricted invasive plant based on it having significant adverse impacts in Queensland. From the desktop results four species are Category 3 listed under the Biosecurity Act and one WoNS ( Latana camara ).
