related injuries, this is a significant impact on an endangered species. The local sea turtle population, including the green turtle and loggerhead turtle, are currently at risk of fibropapillomatosis and in particular a new corneal strand of the virus which has resulted in a declining population. The increased prevalence of this virus has been linked to environmental factors such spikes in seasonal water temperatures and harmful algae bloom. The rise of cyanobacteria in the Cape Byron Marine Park is also linked with the increase of pollution. Coastal development around the Cape Byron Marine Park is a concern on the nesting areas of the migratory little tern. Little terns are highly sensitive to human disturbance and a decrease in suitable habitat impacts on the population size due to a decrease in adequate roosting and breeding grounds. Little terns are also impacted by pollution as poor water quality is known to negatively affect their food intake capacity. Coastal developments have also been known to impact on the local saltmarsh and mangrove communities which are critical habitat for several species of marine life and birdlife. Climate change is affecting the Cape Byron Marine Park in several ways. It is altering the species range shifts which can impact finely balanced ecosystems. Examples of this has been seen through the identification of several tropical species identified within the Cape Byron Marine Park. There is also direct link between the rising levels of CO2 in the atmosphere, the oceans become warmer and the lowering of the ocean's pH levels (ocean acidification). An increase in acidification and warmer water leads to a decrease in carbonates which are attributed to coral bleaching as mass bleaching occurs when sea temperatures have exceeded average temperatures by 1 degree for more than several weeks. This will impact negatively on the rare back coral trees (Antipathes grandis) found within the Cape Byron Marine Park. Changes in water temperature that are associated with climate change are also expected to impacted on the life cycle of many species as evidenced by the loggerhead turtle (Caretta caretta) change in nesting patterns and times, this again could lead to an unbalanced ecosystem which could have detrimental effects on other species which rely on the loggerhead turtle for survival. Management The NSW marine parks have been declared under the Marine Parks Act 1997 and are managed by NSW Department of Primary Industries staff. The act aims to
