Stormwater flows along the first kilometre of urban streams requires energy and nutrient loads to be managed effectively to ensure the downstream integrity of the riparian systems can be maintained. The Popes Glen Bushcare Group, with the support of the Blue Mountains Council have explored and implemented a variety of highly successful soft-engineering strategies to [...]

Arid landscapes that have lost their topsoil are subjected to erosive forces of wind and water to form a clay crust that prevents the growth of vegetation. Ray Thompson explains the technique of waterponding, which captures and directs water, slowing runoff and creating an environment for vegetation to reestablish. In the long-term wind erosion is [...]

Reconstruction of native plant communities on rock dumps in Kosciusko National Park explores the process of redressing the impacts of 400 disturbed sites that were created during the construction of the Snowy Hydro scheme, a $1,548,443 project. Elizabeth MacPhee talks through the logistics and the process of reshaping steep rock dumps, organic enhancement with scavenged [...]
