The TCT wants the State Government to increase resources for the Parks and Wildlife Service to manage weeds in the states national parks and reserves (see Public Reserve Management).

The TCT wants increased resources for the Department of Primary Industries, Parks, Water and Environment to enable rapid responses to eradicate new weed introductions, research to identify the likely impacts of climate change on weed risks and weed management, and the establishment of a weed hygiene and monitoring program.

The TCT supports a ‘Plants Permitted List’ approach, where plants will be allowed into Tasmania only if they have been assessed under a weed risk assessment as having a low weed potential. Currently Tasmania has a prohibited plants system where plants are allowed entry into the state unless they have been assessed and found to have significant weed risk.

Tasmanian Weed Alert Network

The TCT has received funding from the Tasmanian Community Fund to re-establish the Tasmanian Weed Alert Network during 2009–2011. The project is being run in collaboration with the Department of Primary Industries, Water, Parks and Environment’s Weed Management Section, Tasmanian Herbarium, Tasmanian Farmers and Graziers Association and the Tasmanian Weed Society. This project aims to establish the Tasmanian Weed Alert Network as a self-sustaining network of volunteers which assists with preventing the establishment of new weeds in Tasmania.

On-ground weed control

The TCT also runs strategically important on-ground weed control projects such as the current ‘Boxthorn control and maintenance on Twelve Islands’. For more information on this project see the Tasmanian Conservationist, June 2009.

Feral animals

 Implementation of Cat Management Act

The Tasmanian Parliament passed the Cat Management Act in November 2009 and from 1 July 2010 a range of measures will be introduced to control domestic and feral cats. The TCT takes a great deal of credit for convincing the State Government to proceed with legislation and for many of the specific measures that have been adopted.

More funding is needed for implementation of the Cat Management Act:

  • to establish and maintain a state-wide cat breeder register and licensing system for authorised officers
  • for the RSPCA to provide subsidised cat de-sexing and microchipping program during the four years before these measures become compulsory
  • for the RSPCA and cat centres to increase cat housing facilities, to cater for the likely increase in cats being abandoned and to dispose of them through adoptions or euthanasia
  • to establish and run a four-year educational program to encourage community acceptance of and compliance with the new legislation

Community cat management projects

For more than three years the TCT has actively supported and helped to fund the Kingborough Community Cat Control Project. The project has worked to promote responsible cat ownership and runs a volunteer-based feral cat trapping program. For information contact Kingborough Council, phone 03 6211 8297, cat.bruny@parks.tas.gov.au

General ‘feral animal management program’

Feral animal management in Tasmania has always been somewhat ad hoc, normally targeting individual species at specific locations (usually offshore islands) and often dependent on Australian Government funding which fails to enable completion of the projects. Very little effort has been made to engage the community and private landowners in active management of feral animal species.

In its most recent submission on the State Budget, the TCT proposed the State Government establish a broad ‘feral animal control and eradication program’ targeting a range of the feral animal species featured in Feral Animals of Tasmania, an innovative new publication designed to improve community knowledge and understanding of feral animals, and to encourage the community to become involved in reporting and managing them.

The government program should follow the prioritisation process used in Feral Animals of Tasmania, with the highest priority being to prevent new feral species establishing or eradicating those that have recently been introduced and are not widely distributed. The program should also be planned in consultation with the community; where possible, the community should be given an active role in monitoring, reporting and controlling feral animal species. Feral species we anticipate a Tasmanian program targeting include: pig, goat, cat, Indian myna, rainbow lorikeet, carp, oriental weatherloach, gambusia and long-necked turtle.


The TCT is a strong supporter of the State Government’s Fox Eradication Program (FEP) and believes the program must have an immediate increase in funding to ensure successful eradication of foxes from Tasmania. The FEP has endorsed most of the recommendations of the independent review by the New Zealand company Landcare Research. We are firmly of the view the new strategies have the potential to eradicate foxes but inadequate resourcing is slowing down their implementation and may reduce the thoroughness of the actions taken.

The TCT is represented on the Stakeholder Reference Group for the Fox Eradication Program.

WHA feral animal management

There is an urgent need for the Tasmanian Wilderness World Heritage Area managers to complete the long-mooted WHA Invasive Species Strategy and for additional resources to be provided by the State Government to ensure it is implemented. We call on the Tasmanian Government to support the completion of the WHA Invasive Species Strategy as a matter of urgency and to provide resources to implement it.

Stop Invasive Species Alliance

The TCT is the only Tasmanian member of the Stop Invasive Species Alliance, a national group launched recently to lobby for national leadership in invasive species prevention and management. Further information regarding the Stop Invasive Species Alliance is available from http://stopinvasives.org.au/

Details of the TCT’s proposals in relation to feral animals can be found in the 'TCT submission on the 2010-2011 State Budget'.
