Weeds environmental - Shoalhaven City Council

Environmental weed management

Council operates a series of weed specific control programs for a range of environmental weeds on Council managed land.  Most of these programs are funded under Federal or State Government Programs.

Madeira vine

Madeira vine is an aggressive climbing weed which smothers trees and shrubs and is transported along waterways by floods.  It has been identified at 350 sites in the Shoalhaven.  It is difficult and time consuming to control.   During 2011 and 2012, Council will assist any landowner in controlling madeira vine on their property.  Send email with details of name, contact, address of infestation to council@shoalhaven.nsw.gov.au.

In March 2012, Council commenced a program to release a biological control (Plectonycha correntina, a leaf eating beetle) at the larger and more difficult Madeira sites. The first release was on the Manildra industrial site in Bomaderry. Read the Press release, the Final Risk Analysis by Biosecurity Australia

Lantana is a Weed of National Significance and is being treated under several Council and Landcare projects.  Landowners have a legal responsibility to control lantana on their property, as specified in a management plan for the property.

  • Council assistance for private owners

Council is able to offer relatively small amounts of assistance to private landowners for lantana control in specified target locations during 2011.

  • Other Council lantana control programs.

Council is tackling lantana on a range of priority Council-owned properties. See following table.

Privet – small and broad leaved

Privet in urban areas

Privet is a declared noxious weed in all urban areas of the Shoalhaven.  All urban landowners have a responsibility to stop privet from flowering and fruiting.  

Privet in rural areas

Council was funded for a rural privet control program between 2002 and 2010.  Large areas of the Shoalhaven were treated under this program, to the extent that privet has been reduced to a relatively minor weed over most of the rural landscape.  In some areas, landcare groups are continuing follow up on these areas.

Privet control on the Lake Yarrunga foreshore, Kangaroo Valley

Council has contracted with the Sydney Catchment Authority to undertake the complete control of privet on the foreshore of Lake Yarrunga in Kangaroo Valley. This project commenced in 2008 and will be completed in 2012.

Bitou Bush and Boneseed

Bitou bush is a South African plant and has become an aggressive noxious coastal weed that has invaded over 80% of the NSW coastline. Council is working in partnership with all southern NSW land management agencies and private property owners to control the ecological impact of bitou bush along our entire coastal zone. Bitou Bush is a listed as a Weed of National Significance and the National Southern Containment Line is located at the Sussex Inlet river, so all infestations below this geographical line are a national priority for control.
Council has been addressing bitou bush infestations for almost 20 years. Members of many coastal Bushcare groups contribute significantly to the control of this weed in the Shoalhaven. Integrated control methods are utilised, depending on the density of infestations. In the past, helicopter aerial spraying techniques have been employed, but infestation levels have now been significantly reduced in the Shoalhaven to require only ground control methods.

Bitou bush is a sprawling evergreen woody shrub that smothers native vegetation. The glossy green leaves and bright yellow daisy-like flowers that appear in autumn and winter make bitou bush easily identifiable on the sand dunes. Follow the link to more facts about bitou bush in Australia.

Council would appreciate reports of any sightings of bitou bush. If you spot a plant that you think may be bitou bush please ring 0434 566 273 or (02) 4429 3422.  Another way to assist with this campaign is to join a Council Bushcare group and assist in the weed control programs along the coast.

Sea spurge

Sea spurge is an invasive beach weed which is very dense across the entire southern coastline of Australia.  It has been slowly creeping up the NSW South Coast during the past 50 years.During 2009 and 2010, Council cooperated with other southern councils and National parks to survey all beaches on the NSW South Coast, and to treat all known infestations.  Up to 6 treatment sessions were conducted at each site. In the Shoalhaven, the worst infestations on Council land were found at Cudmirrah and Wairo beaches.  Boodoree, Conjola and Murramurang contained the worst National Park sites.

Sea spurge has a long viable seed life in the sand, and additional seeds will be washed onto the beaches from southern infestations.  People who find sea spurge on beaches should report it to the responsible authorities, and remove it if that is feasible.  Be sure to wear gloves when hand pulling sea spurge due to its toxic sap.
