Human impacts in the marine environment are extensive and, unfortunately, Australia is home to some of the world's best known examples of large-scale habitat loss, especially of seagrass ecosystems. CMER's research in this theme focuses on a number of pressures such as climate change, reduced water quality (for example, light reduction due to dredging and eutrophication), fishing and invasive species. Much of our research at CMER attempts to determine the thresholds of human impact beyond which marine ecosystems will show change or may be unable to recover. By establishing how marine habitats will respond to human pressures, our research leads to recommendations for conservation and management strategies to ameliorate human impacts.
