Does stream restoration / rehabilitation have any ecological effect?
Around Australia and the World, billions of dollars are being spent on stream restoration and rehabilitation. The vast majority of this money is spent on “on-the-ground” works (i.e. planting the trees). Almost nothing is spent on the important question of whether or not the actions have any ecological benefit. In this project, you would focus upon a restoration technique or project of your choice, and choose a biological endpoint logically linked to that restoration (e.g. in-stream habitat restoration and macroinvertebrates). Comparing biological ‘quality’ in degraded, pristine and restored areas will provide evidence as to the effectiveness of the restoration program. • Modelling the effects of degradation on river ecology Predictive models are increasingly being used to provide answers to questions of what will happen to river ecosystems when they are subjected to various sources of degradation or restorative management actions. For the most part, the structure of these models is der
