Weeds are a serious environmental and agricultural problem throughout Australia, costing in excess of $4 billion each year in management and lost production, with a similar figure estimated for impacts on environmental conservation, amenity and tourism (Australian Weeds Strategy 2006).
In native bushland, weeds outcompete indigenous flora, smothering the vegetation and, in severe cases, creating a monoculture lacking the diversity to sustain populations of native fauna. In agricultural settings, weeds reduce land value by infiltrating crops and paddocks, contaminating produce, decreasing carrying capacity, restricting stock and human access and causing health problems to animals and humans. Weeds also reduce the amenity value of natural areas by hindering or, in some cases, entirely preventing access for recreational purposes.
Many of the problematic species have escaped from gardens and ornamental plantings to become widespread. Gardeners and hobby farmers, of whom there are many in the Molonglo Catchment, have an opportunity to effectively manage existing weeds to prevent the problem from worsening and prevent additional species from escaping and invading the natural bushland. A strategic approach to weed management is required to address the problem, and weed control needs to be considered a priority by all members of the community, whether responsible for a broad scale farming enterprise or a suburban back yard.
This information pack is designed to help you, as a member of the Molonglo Catchment community, identify problem species and make it easy for you to carry out your responsibilities as a land manager/occupier in controlling serious invasive plants. Using the information in this pack will assist you to control weeds more effectively (thus saving money, effort and time), improve the productivity of your land, be a good neighbour and enhance our natural landscapes.
Implementing coordinated, strategic weed control now will save future costs and ensure we leave a legacy, rather than a liability, to future generations.
Our sincere thanks go to the following people for the provision of the large number of high quality photographs which make this information pack so useful.
We would particularly like to thank Jackie Miles and Max Campbell who provided the majority of the photos.

About the Weed Information Pack
The Molonglo Catchment Weed Information Pack was developed by the Molonglo Conservation Group (MCG) with assistance from the Southern Tablelands and South Coast Noxious Plants Committee, Geoff Butler, Queanbeyan City Council, Cooma-Monaro Shire Council, the Murrumbidgee Catchment Management Authority (CMA), the ACT Government, Palerang Shire Council and various other contributing parties, to whom we are very grateful, mentioned in the acknowledgements.
Particular thanks must be given to Jackie Miles and Max Campbell for sharing their collection of weed photographs, adding immeasurably to the value of the package.
Compiled by Zoe Wood. Edited by Geoff Butler, Kerrin Styles, Jim Darrant, Jason Robinson, Lynton Bond, Bruce Taloni, Tom Baker, Maryke Booth, Sandra Lloyd, John Bruggeman and Claudia Nye.
The Molonglo Catchment Group was supported by the ACT Government through the Australian Government’s Natural Heritage Trust and the National Action Plan for Salinity and Water Quality under the Getting Equipped program, another Living Environment Project.
Additional support is provided by the Murrumbidgee CMA by locating the Coordinator in the CMA’s Queanbeyan Office. Funding was also provided by the Queanbeyan City Council, ACT Government, Cooma-Monaro Shire Council, Landcare Australia Ltd and Australia Post for developing this package.
