Identify possible climate change refugia which may also serve as translocation sites in order to secure the species future under a changing climate.
Alteration to the natural flow regimes of rivers and streams and their floodplains and wetlands and Anthropogenic Climate Change are listed as Key Threatening Processes under the Threatened Species Conservation Act 1995. 12.

As G. bredboensis grows in periodically waterlogged areas; changes in hydrology and stream flow associated with projected declines in rainfall (Hennessy et al. 2004) or water extraction from the Bredbo River may result in drying of the habitat.
