One of the most significant environmental challenges facing Western Australia is the minimisation of the impact of weeds. In the relatively short history of this State since European settlement, some 1155 exotic plant species have established as weeds in our diverse and generally fragile ecosystems. While development for agriculture, mining, transport and housing must by its nature result in some change to the State’s flora, the introduction of weedy plant species has caused serious impacts which cause great concern.
Weeds now pose a serious threat to many of the State’s ecosystems, and impose high annual costs on agricultural industries. Weeds …

Eutrophication is essentially the nutrient enrichment of waterways leading to algal growth. It must be controlled to maintain sustainable agricultural systems and the main mechanisms of control are stabilising catchment processes and reducing nutrient output.
Eutrophication can be defined as 'the nutrient enrichment of waters which results in the stimulation of an array of symptomatic changes, among which increased production of algae and macrophytes, deterioration of water quality and other symptomatic changes, are found to be undesirable and interfere with water uses' (OECD 1982). The word eutrophic is a Greek word that means 'well fed'. The food referred to is …
