Policy, Institutional and Managerial Considerations in Managing Weeds with a Commercial Value

Weeds cost the Australian economy millions of dollars each year in lost production, eradication, containment and management, however there has been very little effort placed on assessing or valuing the ecological impact of these weeds.

Prevention and management of aquatic plant invasions in Australian rivers

Australian river systems are threatened by the severe effects of drought, bank erosion, sedimentation, pollutant inputs, urban development, and invasions by exotic aquatic plant species.

This publication is one of a suite of 13 produced as part of a folder showcasing research from the Defeating the Weed Menace Research and Development program.

Quantification of the environmental costs of weeds

The purpose of this project was to quantify (a) the environmental impacts and (b) the relative benefits and costs of control of two tropical invasive grasses. The project reviewed the existing studies on the environmental impact of tropical invasive grass…

Quantifying costs and benefits of buffel grass

Buffel grass is a major environmental weed with the potential to establish in over 60% of mainland Australia.
It is also highly prized by many pastoralists as an exotic pasture grass for livestock. Within these two conflicting views there is a spectrum…

Quantifying costs and benefits of buffel grass

Full Report

Buffel grass (Cenchrus ciliaris) is an introduced pasture grass of significant commercial value but which also presents a major threat to conservation values in the rangelands. This report integrates the outcomes of regional workshops with institutional…

Serrated Tussock: managing native pastures to prevent invasion

This is the final report of Land & Water Australia research project CSU33

This project aims to develop better management practices to stop the spread of Serrated Tussock to new paddocks, new regions and uninfested native grasslands by better understanding of the management system and biophysical factors that affect its spread…

Sleeper and Alert Weeds

Where will they awaken as climate changes?

This fact sheet summarises the work Dr John K. Scott and his colleagues have completed using computer modelling of both plant characteristics and global climate change to predict how 41 of the nationally recognised ‘environmental alert’ species and agricultural ‘sleeper weeds’ are likely to behave as the effects of human-induced climate change become more apparent. It is now scientifically accepted that Australia’s climate is changing and that these changes will (more)...

Understanding and determining mechanisms to prevent invasion in coastal vegetation

We investigated the effect of richness of different growth forms (functional richness), the arrival order (priority effects) and competitive interactions in mediating plant community resilience to invasion events. We constructed mesocosms composed of dune…

Weed management on floodplains

Landscapes and ecosystems are composed of complex networks of interactions; consequently the effects of management actions can be unpredictable.

This publication is one of a suite of 13 produced as part of a folder showcasing research from the Defeating the Weed Menace Research and Development program.

Weeds: One of Australia’s major environmental problems

As the Australian Weeds Strategy recognises “Weeds have major economic, environmental and social impacts in Australia, causing damage to natural landscapes, agricultural lands, waterways and coastal areas”. To a significant extent the Australian Government’s focus on weed management, whether at the research, policy or implementation level, has been on weeds and their impacts on rural production. This is scarcely surprising, given estimates that the agricultural impacts of (more)...

Workshop Report Alice Springs

Economic, Environmental and Social Costs and Benefits of Buffel Grass and its Management

Buffel grass is valued in many regions for its contribution to livestock production, while also being regarded as a threat to biodiversity assets, often within the same region. In 2007 Land and Water Australia funded CSIRO to investigate the relative…

Economic, Environmental and Social Costs and Benefits of Buffel Grass and its Management

Buffel grass is valued in many regions for its contribution to livestock production, while also being regarded as a threat to biodiversity assets, often within the same region. In 2007 Land and Water Australia funded CSIRO to investigate the relative…

Workshop Report North Rockhampton

Economic, Environmental and Social Costs and Benefits of Buffel Grass and its Management

Buffel grass is valued in many regions for its contribution to livestock production, while also being regarded as a threat to biodiversity assets, often within the same region. As part of this research, we (CSIRO) ran a workshop in Rockhampton in November…
