Mysore thorn
Mysore thorn is a perennial shrub, growing to 2-4 metres, or a sprawling climber to 15 metres high, which readily forms a dense impenetrable thicket. It has tap roots and lateral roots. Mysore thorn is a vigorous growing plant capable of climbing and engulfing native vegetation, fences, sheds, bridges and other infrastructure. The long spines of the Mysore thorn can inflict serious injury to humans and animals, native and domestic. Mysore thorn forms dense thickets restricting access of stock and machinery to vital areas like water, pastures and roads. Thorns on the stems are straight or hooked and aid in [...]

Cestrum parqui
Green cestrum
Green cestrum is a native of South America. It was introduced into Australia to be used as an ornamental shrub for gardens. Since that time, green cestrum has spread rapidly from people’s gardens and has become naturalised throughout eastern New South Wales. Green cestrum’s most common source of spread is droppings from birds that have eaten the berries. Seed is also readily spread through watercourses and by flood events. In NSW green cestrum can be found growing in the Hunter Valley, the outer metropolitan areas of Sydney, the North Coast and the north-west, central west and south-west of the state. [...]

Solanum chrysotrichum
Giant devil’s fig
Giant devil’s fig originated from Central America. A member of the Solanaceae family, it is a tall perennial shrub, three metres to four metres high, with a similar growth habit to wild tobacco. Flowering from Autumn to Spring, it reproduces from seed usually spread by birds and bats. It rapidly invades disturbed sites, for instance, where the ground was recently bulldozed. Twenty years ago this plant was restricted to the Tuntable Creek area. In the 2010-2011 season we have really seen the invasion into areas as widespread as Toonumbar, to the west. A single specimen was found near the first [...]

Lantana species
Lantana
Red Lantana has a major impact on agriculture and the environment in many parts of the North Coast region. This plan aims to help coordinate control activities in order to reduce these impacts. There are numerous forms of lantana growing in Australia based on flower colour and other vegetative characters. Some forms produce few or no seeds whilst other forms seed heavily and cause major impacts on agriculture and the environment. The weedy forms of lantana are estimated to infest over 4 million hectares in Australia (Parsons and Cuthbertson (2001). Annual agricultural losses are estimated to be $7.7 million, including [...]

Sporobolus fertilis
Giant Parramatta Grass
Weedy Sporobolus grasses such as Giant Parramatta Grass (GPG) and Giant Rats Tail Grass (GRTG) are aggressive weeds that significantly threaten a range of agricultural industries within the NSW North Coast region and many other parts of Australia. They also have significant impacts on the environment, recreation and tourism. GPG has invaded large areas of pasture in the region whilst GRTG is currently spreading. sporobolus_rcp
