This unit provides a theoretical and practical basis for the rehabilitation of aquatic and terrestrial ecosystems following a range of types of disturbance. The unit addresses theoretical concepts of ecosystem rehabilitation such as disturbance, ecosystem resilience and successional theories as well as policy and social considerations in the rehabilitation of ecosystems. The applied aspects of the unit will focus on a stepwise rehabilitation procedure that has broad application. A number of case studies involving research, government agency and private industry projects will be used to link theoretical and applied aspects of the unit. The practical components focus on the assessment of a range of rehabilitation projects (mine site, wetland, riverine, agricultural and forestry), the development of a rehabilitation plan and presentation of research findings in a seminar.
