The recognised threats to biodiversity are numerous and wide ranging in the Southern Mt Lofty Ranges. The main threat to plants, animals and natural systems in the Adelaide Hills is habitat destruction. Since European settlement, the region's natural assets have been increasingly exposed to vegetation clearing activities, introduced weeds and feral animals, plant diseases and pathogens such as Phytophthora or dieback, altered fire regimes and overgrazing. In addition, a greater understanding of new and emerging threats, such as climate change and water scarcity, have also highlighted their significance as a key driver threatening biodiversity.
The ongoing management of threats across the region is increasingly necessary to maintain robust ecosystems that are more resilient in the face of intensifying global warming, and bolstering their ability to self-sustain and support native species.
