Weed Management Plan

The Weed Management Plan Gamba Grass 2020 – 2030 (the gamba plan) requires annual reporting to assess if implementation of the plan is achieving its specified goal, objectives and actions. The plan was developed in 2020 and has been revised earlier this year in accordance with the Weeds Management Act 2001. 

This annual survey has been prepared to enable collaboration with the community and key stakeholders to find out different perspectives on how well implementation of the gamba plan is tracking.

 In order to do this, survey questions are included that ask questions directly against each of the 5 goals of the gamba plan: 

Goal 1. Eradicate gamba grass from the Class A zone 

Goal 2. Contain and control gamba grass by actively managing infestations across the Class B zone and preventing spread into new areas

Goal 3. Protect priority environmental and cultural assets from the impacts of gamba grass

Goal 4. Increase community capacity and willingness to participate in gamba grass management

Goal 5. Implement transparent and accountable compliance, monitoring and reporting processes

The answers received are used for the purpose of assessing performance against the gamba plan and informing the 2024 gamba grass annual report on plan progress. De-identified feedback will be made available to the public through the annual report, unless you choose for your feedback not to be included.

Before completing this survey, below information is available for:

• Gamba grass class A and B zone declaration boundaries
• Anonymously reporting a gamba concern online at nt.gov.au/gamba
• Gamba identification and control videos
• Gamba research at the National Environmental Science Program (NESP) webpage
• Landcare NT to get involved with gamba grass control
• 2023 gamba grass annual report

Mesquite (Prosopis spp.) is a classed as a very high risk weed in the Northern Territory (NT) and has been declared as a class A weed in the NT under the Weeds Management Act 2001 (the Act). Mesquite is a Weed of National Significance under the National Weeds Strategy. Mesquite is a thorny single or multi-stemmed tree or shrubby bush with a spreading canopy of 3m to 15m tall. Pastoralism is the main land use most susceptible to invasion where severe mesquite infestations can reduce the production of native and introduced pasture species by up to 90%. 

A new DRAFT 10 year Weed Management Plan for Mesquite 2024 – 2034 has been developed that sets out the legal requirements for managing mesquite on land in the NT. This is the second 10 year weed management plan for mesquite with the last plan expiring in 2022. The Department of Environment, Parks and Water Security seeks feedback on this draft plan.

Prickly acacia (Vachellia nilotica) is classed as a very high risk weed in the Northern Territory (NT) and has been declared a class A weed in the NT under the Weeds Management Act 2001 (the Act). Prickly acacia is a Weed of National Significance under the National Weeds Strategy. Prickly acacia is a thorny, umbrella-shaped tress that grows up to 10m tall and can form dense thickets. Prickly acacia infests more than 6.6 million hectares of Australia. It threatens agriculture and the environment across most of northern Australia, including important production areas of the NT such as the Barkly tablelands.

A new DRAFT 10 year Weed Management Plan for Prickly Acacia 2024 – 2034 has been developed that sets out the legal requirements for managing prickly acacia on land in the NT. This is the second 10 year weed management plan for Prickly Acacia with the last plan expiring in 2022. The Department of Environment, Parks and Water Security seeks feedback on this draft plan.

Mimosa (Mimosa pigra) is classed as a very high risk weed in the Northern Territory (NT) and has been declared as a class A and B weed in the NT under the Weeds Management Act 2001 (the Act). Mimosa is also a Weed of National Significance under the National Weeds Strategy.

Mimosa is a thorny shrub that is particularly invasive on floodplains, wetlands and riparian habitats. Mimosa has proven to be extremely invasive on floodplains where it forms vast monocultures, significantly impacting wetland ecosystems, affecting grazing production and restricting social and cultural land use across the Top End.

Under the Act a Weed Management Plan can be developed for the purposes of managing declared weeds across the NT. The owner and occupier of land on which a declared weed is present must comply with a weed management plan relating to the weed.

A new 10 year Weed Management Plan for Mimosa 2022 – 2032 has been developed that sets out the legal requirements for managing mimosa on land in the NT. This is the second 10 year weed management plan for mimosa; the last plan commenced in 2010.  

The Department of Environment, Parks and Water Security seeks feedback from the community on the draft Weed Management Plan for Mimosa 2022 – 2032.

For transparency, all comments received will be de-identified and published along with the final Weed Management Plan for Mimosa 2022 – 2032, unless you choose for comments not to be included.

Bellyache bush (Jatropha gossypiifolia) is classed as a very high risk weed in the Northern Territory (NT) and has been declared a class A and B weed in the NT under the Weeds Management Act 2001 (the Act). Bellyache bush is also a Weed of National Significance under the National Weeds Strategy.

Bellyache bush is a multi-stemmed perennial shrub. It is extremely adept at spreading into new areas and threatens pastoral enterprises and other land managers by affecting mustering, taking over valuable grazing land and poisoning stock.

Under the Act a Weed Management Plan can be developed for the purposes of managing declared weeds across the NT. The owner and occupier of land on which a declared weed is present must comply with a weed management plan relating to the weed.

A new 10 year Weed Management Plan for Bellyache Bush 2022 – 2032 has been developed that sets out the legal requirements for managing bellyache bush on land in the NT. This is the second 10 year weed management plan for bellyache bush; the last plan commenced in 2010.

The Department of Environment, Parks and Water Security seeks feedback from the community on the draft Weed Management Plan for Bellyache Bush 2022 – 2032.

For transparency, all comments received will be de-identified and published along with the final Weed Management Plan for Bellyache Bush 2022 – 2032, unless you choose for comments not to be included.
