Cecropia are rapidly growing trees originating from tropical America. They are pioneer species that can quickly establish in disturbed areas and have become weeds in South America, Malaysia and Africa. In the past, Cecropia species (including Cecropia peltata) have been imported into Australia for private plant collections, but all known plants have been destroyed due to their invasive potential. They are listed as Class 2 noxious weeds across the North Coast region. They are a rapidly growing tree, usually 10-20 metres tall, but can reach up to 25 metres. The plants can be distinguished by the large U-shaped leaf scars […]


Black willow

Black willow is a deciduous, rapidly-growing tree to about 20 metres tall with one, or less often up to four, trunks. It is distinguished by its non-drooping habit and twigs which are shiny and red-brown when exposed to sun. Other distinguishing features include thin leaves which are almost equally green on both sides and deeply fissured grey bark on stems more than 10 cm in diameter. Black willow hybridises with other willows. The trees can reach a height of 43 metres, with a trunk diameter of 1.2 metres. Leaves are shiny light green above, duller below and often velvety along […]


Chinese tallow

(Syn. Sapium sebiferum) The Chinese Tallow is native to South-East Asia, mainly China, and was introduced as an ornamental tree in streetscapes and gardens. Chinese Tallow is a Class 3 Noxious Weed in the North Coast area and must be fully and continuously suppressed and destroyed. This weed is invasive and alters nutrient cycles, quickly forming dense monocultures and displacing native vegetation. While the Chinese Tallow appears to favour wetter areas such as swamps, it can grow in drier conditions and has been planted as an ornamental tree in streets and gardens. It is easily recognised by its heart-shaped leaves […]


Rhus tree

Rhus is a deciduous small tree, growing to between five metres and eight metres high with smooth, grey bark. The 5 mm-wide to 11 mm-wide fruits are round but slightly flattened in one plane, pale brown and hard textured with a papery skin. They hang in clusters on the tree through winter, falling in spring The rhus tree has compound leaves between 10 cm and 30 cm long with between four pairs and seven pairs of leaflets. There is an unpaired terminal leaflet at the tip of each leaf. Each leaflet has a long tapered tip and a rounded asymmetric […]

Broad-leaf privet

Broad-leaf privet originates from eastern Asia and has become a widespread weed of disturbed land, pastoral areas and native bushland in coastal NSW. It grows as an evergreen shrub or small tree to a height of 4-10 metres. The brown bark is covered in small white lenticels (pores that allow gas exchange). Pointed oval-shaped leaves occur in opposite pairs, and are 4-13 cm long and 3-6 cm wide. The upper leaf surface is dark green and glossy or shiny, while the under-surface is paler with distinct veins. Leaves are hairless. Cream or white tubular flowers with four petal-like lobes occur […]

miconia leaf 


Miconia, also known as velvet tree, is a potentially devastating weed of Australian rainforests. All miconia species are declared noxious throughout NSW as a Class 1 weed and must be eradicated from the land and the land must be kept free of the plant. As a notifiable weed, all outbreaks must be reported to your Local Control Authority. If you find this weed in your area or see something that may be miconia, contact the North Coast Weeds Advisory Committee, Far North Coast Weeds (FNCW) or Industry & Investment NSW immediately. Miconia is a rainforest tree native to South America […]


Broad Leaf Pepper Tree

Broad-leaved Pepper Tree (BLPT), also known as Brazilian pepper tree, is an invasive tree capable of reaching 15 metres in height that originated in Brazil, Argentina and Paraguay. BLPT is one of the most destructive weeds in Hawaii, Florida and the Bahamas, taking over vast areas of native vegetation. This species is also recorded as a weed in South Africa. BLPT has been cultivated as a garden plant in many countries and has been cultivated in Australia since the mid 1860s. This species is now naturalised in south-east Queensland, north-east New South Wales and parts of Western Australia. BLPT favours similar habitats to Groundsel Bush (Baccharis […]


Chinese celtis

Chinese celtis is an invasive tree growing up to 20 metres tall. It originated from China, Japan and Korea and was introduced into Australia as an ornamental and shade tree. Celtis has become a major environmental weed in south-east Queensland, expanding rapidly over recent years into major infestations along riparian zones in the Sunshine Coast hinterland and the Ipswich area. In north-east New South Wales significant but controllable infestations occur in and near a number of urban areas where old ornamental plantings act as a seed source and in rural areas around Kyogle where it was planted as an ornamental […]


Camphor Laurel

Camphor laurels were introduced to Australia from South East Asia in the mid 19th century and were reported as a weed by 1900. They have spread at a phenomenal rate over the past 20 years. It is estimated that over 30% of all camphor laurels in the north coast region are less than 3 metres high, or under 3 years of age (not including small seedlings). Of serious concern to other areastext south of the region is that camphor laurels recently began setting seed on Dorrigo plateau (elevation approx. 700m) for the first time. Camphor laurels threaten both agricultural lands […]
