The control of weeds and pest animals takes up a lot of time and money once they are established in an area. With the right knowledge and practical skills a community can efficiently contain the weeds and pests that are already established and prevent new ones from taking hold.
A weed is considered as a plant that requires some form of action to reduce what are perceived as harmful effects on the economy, the environment, human health and or amenity.
Environmental weeds are plants that invade native ecosystems and adversely affect the survival of indigenous flora and fauna. Environmental weeds can be foreign plants accidentally or intentionally introduced into Australia, or they can be native plants that have become weedy due to inappropriate management, or because they are outside of their normal range.
Declared weeds are introduced plants listed under the Weed Management Act 1999.
Declared weeds are recognised as causing:
- reduced farm production
- degradation of the State’s natural or physical resources
- degradation of ecological processes, or
- reduction in the genetic diversity of native plants.
Once plants are declared as weeds under the Act, there are restrictions on their trade, sale, import, movement and disposal.
Weed Management Strategies
Priority Weeds in Kingborough
Most of the highest priority weeds are those we rarely see; they have only been seen at a few places but have the potential to spread quickly. We aim to completely eradicate these plants and check to make sure they don’t come back.
Weeds that occur all over Kingborough such as Gorse and Spanish heath require a lot more time and money to control. Therefore, we aim to ‘contain’ these weeds, which means preventing them from spreading further. We remove small scattered infestations and actively control them in areas where they may be easily spread, such as on roadsides. Take a look at our Kingborough Weed Strategy Management and Action Plan 2015 – 2027 for more information.
