The definition of weed is simply a plant that is growing where it is not wanted. For instance, grass is valued as part of a lawn, but viewed as a weed in a vegetable garden. Environmental weeds are non-native plants that invade bushland and threaten the native plants through competing for resources. Declared weeds are plants listed in the Weed Management Act 1999 as plants that have potential adverse impact in Tasmania.
Reporting a Weed
If you think you have seen one of these weeds Please take two photographs, one of the entire plant and one close up of the leaves and flowers, and don’t forget to note the location and then send the information to NRM Unit for us to confirm identification and action eradication measure if appropriate.
Arrive at your destination with clean vehicles and clean, healthy stock. Review the activities you have in place to protect your farm from weeds, pests and diseases. Biosecurity activities protect farm productivity, in turn protecting farm profitability and the industry as a whole. Consider the risks to your property and plan to reduce them through biosecurity measures. For more information: NRM South’s Farm Biosecurity Guide

While Council does conduct and coordinate weed control programs on public land from time to time, land-owners are also encouraged to take responsibility for the control of weeds on their own property and adjoining roadside.
If you are interested in controlling weeds without using herbicides consider using steam or boiling water methods. These documents have been developed to assist you in developing your own weed management plan unique to your property:

At this stage none of the Waste Transfer Stations in the Huon Valley accept declared weeds.
The options available to you all involve the use of heat to kill any viable weed seeds:
- Place weed material in double rubbish bags with a splash of water and leave in the sun for a period of at least 3 months before disposing of in the general waste.
- Incinerate in an enclosed (to contain seed material and increase heat) incinerator or drum.
- Hot compost to 60oC+ before using composted materials.
Below are the Huon Valley’s priority weeds listed under the category associated with a particular management approach.
Further details can be found in the Huon Valley Weed Management Strategy .
