Theme 4.00

Reintroductions and refugia

Species close to extinction require special effort in the hope that new opportunities to deal with threats in the wild may emerge and increase their chances of survival.

Intensive management of threatened species involving zoos, fenced enclosures, nest boxes, translocation of individuals and quarantine from disease is expensive. Research is urgently needed to improve the cost-effectiveness of conservation interventions.

This theme will focus on:

  • Saving species on Australian islands
  • Increased security of threatened plants through translocation
  • Improved management of refugia in the landscape.

Translocation, reintroduction and conservation fencing for threatened fauna

Project: 4.1
Whether moving species into fenced areas, intensively managed habitats or outside its previous habitat - translocating threatened species presents a number of challenges.

This project will research the most feasible and cost-effective translocation strategies to boost the size and long-term viability of wild populations. This will include improved planning for, and implementation of, translocations of mammals, birds, reptiles and frogs.

Can assisted gene flow increase the resilience of terrestrial-breeding frogs to a drying climate?

Project: 4.1.6
Assisted gene flow is an emerging method to aid species to adapt to new conditions, such as those created by climate change. It involves the movement of individuals (or their genes) from one population to another. This project will investigate whether assisted gene flow could enhance the resilience of two species of non-threatened amphibians from the south-west of Australia to increasingly dry conditions.

Improving conservation outcomes for critically endangered white-bellied frogs

Project: 4.1.8
White-bellied frogs are a critically endangered species that are endemic to the Margaret River region of Western Australia. The species has undergone continued population declines, despite careful management. This project will target knowledge gaps around factors contributing to population declines, as well as better resolve the specific habitat and hydrological requirements of this species.

Learning from mammal translocations

Project: 4.1.3
Australian Wildlife Conservancy is undertaking a major project to re-establish populations of 10 regionally-extinct mammals, including nine threatened species, at Mt Gibson Wildlife Sanctuary, Western Australia. The reintroductions will integrate monitoring and research activities in order to improve the conduct of future reintroductions in Australia.

Saving species on Australian islands

Project: 4.2
This project will help shape on-ground actions on Australian islands – which are havens for threatened species. It will develop information to more effectively protect Australia’s island biodiversity and create safe refuges for species at risk.

Improving threatened plant reintroduction success

Project: 4.3
Reintroducing threatened plant species can be a risky and expensive undertaking, especially in cases where current knowledge is inadequate. Project 4.3 will fill these knowledge gaps to improve the feasibility and cost-effectiveness of reintroducing threatened plant species.
It will provide practical guidance on how, where and when reintroductions should be implemented to cost effectively minimise the extinction of threatened plants.

Identifying and managing refuges from threats

Project: 4.4
Some locations in Australia are particularly valuable for threatened species because they offer natural protection from introduced predators, diseases, fire, drought, and the effects of climate change. Project 4.4 will locate and identify the features that form natural refugia and the places where conservation efforts will be most effective.
