prioritise actions to protect the species and enhance their recovery, and that projects will be undertaken according to agency priorities and available resources. In order to maximise the conservation outcomes and cost effectiveness of this plan, it is intended that the recovery actions proposed complement, where possible, those of other protected matters.

10 Effects on other native species and biodiversity benefits
By managing northern Tasmanian freshwater ecosystems for the benefit of giant freshwater crayfish, many other native aquatic fauna will also benefit. Tasmania's Natural Values Atlas database lists a number of other threatened species that occur in giant freshwater crayfish habitats, including hydrobiid snails and four species of burrowing crayfish, in addition to non-threatened iconic species such as the platypus. Because of the linkages between riparian and in-stream ecosystems, the protection of riparian zones will benefit riparian and in-stream fauna. Functional, intact riparian zones are directly related to high in-stream biodiversity (Boulton & Brock 1999) and contribute to the floristic diversity of off-reserve areas. Benefits can be effectively achieved by measures to raise awareness of freshwater environments and their conservation management requirements, and by encouraging implementation
