 South Esk heath ("Epacris exserta") is also determined by the "Environment Protection and Biodiversity Conservation Act 1999" to be endangered.Tourism is somewhat of a double-edged blade in this National Park.While tourism is an important form of revenue to ensure ongoing care and maintenance of the park, as well as an important aspect of education regarding the natural world, and conservation of the flora and fauna within the Mole Creek Karst National Park, it is also by far the greatest threat.
