There are 20 flora or fauna listed in the National Values Atlas for the Great Lake area where the Great Lake Adventure Trail will be constructed. Of these, four need to be incorporated into the Feasibility Study with comment as to how they will not be impacted. They are:

  • Tasmanian Devil – there is a state-wide strategy on the management of the Tasmanian Devil which is self-explanatory and easily implemented
  • Ptunarra brown butterfly which is threatened and considered of conservation significance
  • The Isopod (found around Shannon Lagoon) and the Great Lake Isopod – both are rare, threatened and considered of conservation significance and endemic to Tasmania. They are a crustacean and not in abundance.

There are two flora or fauna that will need special mention in the Plan with detail on management. They are:

  • The Liawenee Greenhood. This orchid is considered threatened and of significant conservation value. It’s referred to in the schedule to the Threatened Species Protection Act. Appearing in early summer, recognising the flowers is the only way to identify it as it dies back into a subterranean tuber after flowering. There are 7 – 10 known populations in existence. Estimating the size of the population is difficult unless conditions are favorable for flowering. The largest population on Liawenee Moor (on private land) has a maximum of 500 plants that are loosely clumped. There has been a sighting of 10 plants at Tods Corner and a few plants at Christmas Bay on the western shore of the lake, both on private land. The other four sites are not within the Great Lake area. Management includes:
    • Not overgrazing from November to January
    • Not ploughing or fertilising in their vicinity
    • If found on your land, consider long-term protection
    • Help the search for new populations
    • Help to monitor known populations
  • The Miena Jewel Beetle. This is threatened and considered of conservation significance. It is vulnerable and is currently being considered for up-listing to ‘endangered’. It has been recorded in open subalpine woodland and heath above 900 metres. A good population has been recorded at three locations. The area where the most beetles have been found is in the Liawenee Conservation area at the corner of the Lake Highway and Lake Augusta Road with sightings at Lake Augusta and a sighting at Tods Corner on private land. Threats include loss of habitat through conversion, grazing or fire, illegal collection and climate change. Management includes:
    • Better documenting the distribution of the species
    • increasing public awareness of the species
