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. As part of this research, we (CSIRO) ran a workshop in Rockhampton in November…

Pastoralists' perceptions of the benefits and cost of buffel grass

This report is an attempt to quantify the broad spectrum of benefits and costs of buffel grass to pastoralists, and the likely pastoral response to potential changes in buffel grass management strategies that aim to minimise the environmental costs of…

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…

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…

Evaluating the environmental benefits from managing WoNS in natural ecosystems

Weeds pose a significant threat to natural ecosystems in Australia and consequently large quantities of resources are spent each year to control them. In this project we undertook a desktop analysis to determine the current state of knowledge on how…

Optimising management of core mesquite infestations in Australia

We conducted a three-year field study to test whether the invasiveness of mesquite, and its response to biological control, differs with taxa and climate (between region and years). Permanent study sites were set up and monitored in the core infestations

Effect of land use and peri-urban development on aquatic weeds

The primary objective of the proposed work was to understand the impacts of peri-urban development on aquatic weed invasions. We quantified aquatic weed abundance according to land use through desktop and field-based surveys and classified 24 species in a…

Development of new biocontrol agents for Parkinsonia

Parkinsonia is a Weed of National Significance due to its impacts on the environment and agricultural production. Biological control of this weed is considered essential for its long term management. Classical biological control consists of introducing…

Biological control and ecology of alligator weed

The goal of this project was to improve management of alligator weed in Australia. This was to be accomplished through; 1) testing the host specificity of two herbivorous insects for potential use as biological control agents
