Résumé
The indigenous grass Lachnagrostis filiformis (Fairy grass) has colonised extensive areas of dry lakebeds in western Victoria, Australia during the current (1997-) drought. Large numbers of the plants’ detached seed heads disperse in the wind and lodge against housing, fences, railway lines and other obstacles ... In this study, late season application of Glyphosate based herbicide, slashing, seed broadcasting of Atriplex australasica and Puccinellia perlaxa, grazing and burning were examined ... The results highlight how weed management aimed at achieving short-term goals, without controlling the ecological processes that promote weeds establishment and persistence, can be counter productive in the long-term.
