Threatened species

Hydro Tasmania's threatened species research will help us to conserve species in their habitat. We are particularly interested that we manage our operations to sustain the habitats and conditions of the diverse flora and fauna, especially in the lakes and storages which are subject to varying levels. Levels change due to our operations, drought and flood. The more we know about what is affected, the better we can manage our operations to minimise environmental impacts.

Our environmental team works with others on these projects, such as academics, government agency specialists and our Entura experts.

Lake Pedder discoveries

Hydro Tasmania has completed much work with what once were threatened species at Lake Pedder, read more here >

Central highlands - galaxiid fish

Research into the biology and ecology of galaxiid fish species in Arthurs Lake and Great Lake has shed new light on the four threatened fish species that inhabit these waters.

We commissioned Dr Scott Hardie (Flexible Contracting Services) to lead a research project, in collaboration with Kevin Macfarlane Inland Fisheries Service Biological Consultancy) and Associate Professor Leon Barmuta (University of Tasmania), to assess how water levels influence the galaxiid populations in these lakes. We now know when and where these fish spawn, and what habitat types and environmental conditions are important for breeding to be successful. We use this information to manage water levels to protect these fish species.
