Orange Hawkweed (Heiracium aurantiacum) was first discovered in Kosciuszko National Park (KNP), in the Jagungal Wilderness Area, in December 2003. This species of Hawkweed is a National Environmental Alert List Weed and a Class 1 Noxious Weed in New South Wales (NSW). This species is considered a significant threat to biodiversity and native ecosystems if it is not successfully eradicated (National Heritage Trust 2003, Morgan 2000).

The National Parks and Wildlife Service (NPWS) is required under the Noxious Weeds Act 1993 to; reduce the negative impact of weeds on the economy, community and environment, to restrict the spread and reduce the area of existing significant weeds, such as Orange Hawkweed (OHW).
