Lekhanam      There has been a decline in biodiversity across most regions of South Australia , particularly in agricultural areas where habitats have been destroyed or altered , leaving behind fragmented patches of vegetation . The remnants , and biodiversity they support are under continuing threat . It is important to manage and rehabilitate these areas if further loss of biodiversity is to be avoided . Conserving our biodiversity is extremely important , not only in terms of it's intrinsic values but because many of our economic activities are based on healthy and functioning natural systems . An essential part of ecosystem conservation is the establishment of a comprehensive and we'll managed reserve system . In South Australia this system already contains a wide range of many of our unique ecosystem , from the Sandy and Stony desert areas to mallee , coastal systems and off- shore islands . They are the range of management of programs underway in South Australia to conserve and restore ecosystems both on and off reserves . These programs involve the : Removal of threats such as environmental weeds or grazing by domestic stock and freak animals . Eradication of introduced predators such as foxes and cats . Re-introduction of threatened species and the restoration of habitat through revegetation programs . Management programs are crucial if we are to retain healthy and functioning ecosystems in longer term .
