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 pose a more widespread risk to the State’s bioregions than does salinity, recognised as Western Australia’s most serious environmental challenge. Without a substantial change in the way weed problems are tackled, the long-term impact of weeds on the economy, environment and community may approach, or even exceed, that of salinity.
Development of A Weed Plan for Western Australia (referred to as the ‘State Weed Plan’) was initiated because a wide range of community, industry and government stakeholders recognised that there “had to be a better way” of reducing the impact of weeds.
