Weeds have many adverse impacts on agriculture and the environment and therefore are often targets of eradication attempts. Eradication attempts involve large commitments of labour and financial resources over significant periods of time. Using data from 12 Australian weed eradication attempts the authors compare work hours and expenditure on each attempt for various initial-infestation sizes. Analysis of a limited data set shows: (1) that while the eradication effort increases with the initial area of infestation, the effort applied per hectare actually decreases; (2) that application of a greater work effort was not the reason why completed eradications were successful; and (3) that the larger the initial infestation size, the smaller the amount of...

Ano: 2004 URL: http://purl.umn.edu/12921 ECONOMIC ISSUES RELATING TO WEED MANAGEMENT IN NATURAL ECOSYSTEMS: THE CASE OF SCOTCH BROOM ON BARRINGTON TOPS, NSW AgEcon Odom, Doreen I.S.; Griffith, Garry R.; Sinden, Jack A.. The area of the imported weed Scotch Broom (Cytisus scoparius) is steadily expanding and eliminating natural ecosystems and their habitats of rare and endangered species in Barrington Tops National Park. A research project, funded by the CRC for Weeds Management Systems, has commenced to provide economic information to assist the management of this problem. To provide a focus for the project, the economic issues surrounding the broom problem are explored in this paper. The general economic characteristics of weeds in natural ecosystems are discussed first, and include externalities and public goods. The economic issues in weed management are addressed next, and include the problems of government management, choice of control measure, and sources of...
