 In addition to the environmental threats posed by climate change and root rot fungus, there are several other impacts, posed mainly by humans, that threatened the park.Of most concern from humans are the impacts posed from fishing, tourism and introduced pests such as feral cats and starlings into in the park.Due to the uniqueness of the freshwater and estuarine systems within the park, and wanting to prevent the introduction of pests such as the brown trout, fishing has been banned from the known estuarine and freshwater systems of the park such as Bathurst Harbour, Port Davey and Melaleuca.
