1 Vision


To recognise, identify and meet the challenge of tackling the threat of weeds to the natural environment and to agricultural productivity on King Island

2 Background


The King Island Natural Resource Management Group was established to improve the management of King Island’s natural resources and support the implementation of ecologically and economically sustainable development. To achieve this aim the Group has received funding from the Federal Government’s Natural Heritage Trust and from the King Island Council. The Group is implementing several projects to address Natural resource Management issues including weed invasion.

3 Challenge


A weed is often recognised as a plant growing where it is not wanted. This Strategy recognises weeds as non-native species that have naturalised in the environment, distinguishing them from most garden and agricultural plants. There are currently known to be 183 weed species on King Island.

  • There are 6 Weeds of National Significance (WONS) on King Island.

  • There are records of 21 Declared Weeds on King Island – listed in the Tasmanian Weed Management Act 1999.

  • There are a number of weed species that are currently not widespread but are potentially significant threats to the environment and/or to agriculture.

  • There are a number of existing projects and management practices that have the potential to worsen the weed problem.

  • There is an opportunity to successfully eradicate a number of weed species on King Island.

  • There is a need to control and minimise the threat of a number of weed species.

  • There is a need to protect important and sensitive environments from the threat of weed species.

4 Goals


To meet the challenge of weed management on King Island there are a number of goals to this strategy.

  • To identify and characterise priority weeds on King Island – taking into account social and scientific imperatives to develop appropriate management approaches

  • To improve community awareness and knowledge of weed issues on King Island – to encourage participation

  • To be responsive to State and National legislation and policy - to recognise statutory obligations and to be best placed for funding opportunities

  • To develop processes that will reduce the risk of introduction and spread of weeds on King Island – to ensure prevention and early intervention

  • To develop and implement specific weed control and eradication projects - to co-ordinate actions and maximise their success

5 Objectives


These are measurable outcomes for the Strategy to aim for, to achieve its ‘Goals’.
