Aim: 
Compile evidence for impacts of climate change in eastern Tasmania (Australia)
Type of Study: 
Regional review
Key Results: 
Regional decline in the extent of dense beds of giant kelp, marked changes in the distribution of nearshore fishes and range expansions of other northern warmer-water species. Over-grazing of seaweed beds by a recently established sea urchin is causing a fundamental shift in the structure and dynamics of Tasmanian rocky reef systems
