 The hygiene checks were designed to prevent root rot from becoming a significant threat to these flora species and or communities of the park.In an area that is rich in terms of ecological flora communities, the Southwest National Park is also a wilderness area that is uniquely rich in biodiversity in terms of the variety of fauna species that either have all of their Tasmanian population or a majority of their population inhabiting the park.Within this national park alone there are, as noted by Driessen and Mallick 2003, three species of terrestrial mammals, 10 terrestrial bird species, seven reptile species, three frog species, four freshwater fish and or marine fish that are endemic to this 600-thousand-hectare national park.
