Theme 4.0

Theme 4.0

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: 

  • 4.1 Translocation, reintroduction and conservation fencing for threatened fauna 
  • 4.2 Saving species on Australian islands 
  • 4.3 Increased security of threatened plants through translocation 
  • 4.4 Improved management of refugia in the landscape

Translocation, reintroduction and conservation fencing for threatened fauna

Translocation, reintroduction and conservation fencing for threatened fauna

4.1
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.
Reintroductions inside and outside fences in the ACT

Reintroductions inside and outside fences in the ACT

4.1.2
This project is learning from, and providing strategic and technical support to a number of reintroduction programs within the ACT. This includes examining the feasibility of reintroducing a number of additional species to areas surrounded by a feral-proof fence, and a “beyond-the-fence” trial release of eastern bettong.
Learning from mammal translocations

Learning from mammal translocations

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.

A decision tool for evaluating whether ex situ management is appropriate for a threatened species

4.1.5
Ex situ management (e.g., captive breeding) can be used to increase the viability of a species in the wild by supplementing or creating wild populations. This research project will create an accessible decision tool to aid decision-making and planning for ex situ management of threatened species.

Genetic management and population modelling of translocated fauna

Genetic management and population modelling of translocated fauna

4.1.6.2
This project focuses on the genetic management of mammals translocated as part of a major restoration project underway on Dirk Hartog Island that is led by Western Australia’s Department of Biodiversity, Conservation and Attractions (DBCA). Focal species include the Shark Bay bandicoot, the banded hare-wallaby and the dibbler.
Genetic rescue of mountain pygmy possums and eastern barred bandicoots: Understanding the genomic consequences of genetic rescue

Genetic rescue of mountain pygmy possums and eastern barred bandicoots: Understanding the genomic consequences of genetic rescue

4.1.6.3
Genetic rescue strategies are becoming more important in many threatened species conservation programs. However, an understanding of genomic consequences of a genetic rescue is currently lacking. In this project we will dissect the genomics of genetic rescue in two Australian threatened species, the mountain pygmy-possum and the Victorian eastern barred bandicoot.
Enhancing ecosystem function by reintroductions of digging mammals

Enhancing ecosystem function by reintroductions of digging mammals

4.1.7
Many of Australia’s threatened species, such as bettongs and bandicoots, are considered ecosystem engineers due to the important functional role they provide in landscapes. This project examines what happens to ecosystem processes at sites where digging mammals have been reintroduced.

Understanding genomic variation in the western ringtail possum for adaptive conservation

4.1.8
The western ringtail possum is Critically Endangered. It faces numerous threats that have resulted in highly fragmented populations, including habitat loss, predation by introduced predators and climate change in the south-west of Australia.

Genetic analysis of the Norfolk Island morepork and green parrot

4.1.9
The Norfolk Island morepork (or boobook), Ninox novaeseelandiae undulata, and the Norfolk Island green parrot, Cyanoramphus cookii, are both endemic to Norfolk Island and are listed as Endangered under the EPBC Act. Both are priority species under the Threatened Species Strategy and a priority for management by Norfolk Island National Park.

Re-establishing critical weight range mammals in the northern wheatbelt of Western Australia: Reintroductions to a safe haven free of introduced predators

4.1.11
Introducing threatened mammals to feral predator-free safe havens (islands and fenced reserves) has made an important contribution to their conservation, and the establishment of additional safe havens is a key action of the Australian Government’s Threatened Species Strategy.

Reintroduction plan to rescue the northern eastern bristlebird

4.1.12
The ecologically unique northern population of the eastern bristlebird is among the most threatened Australia birds. This project will develop an emergency action plan that will guide on-the-ground actions to stop the decline, increase the wild population and directly improve long-term persistence.
Saving species on Australian islands

Creation and analysis of a national database of threatened species on Australian islands

4.2.1
This project is establishing a national database of threatened species across all of Australia’s islands, which is helping fill these knowledge gaps, as well as beginning the process of understanding how to best conserve our island-based plants, animals and ecosystems.
Actions for saving threatened species on priority islands

Actions for saving threatened species on priority islands

4.2.2
Although islands are havens for biodiversity, more species extinctions have occurred on Australia’s islands than on its mainland. This project looked at case study islands, focusing on eradicating cats and managing other invasive species to improve threatened species conservation on Stradbroke Island, Maria Island and Bruny Island.

Norfolk Island threatened species conservation

Norfolk Island threatened species conservation

4.2.4
This research seeks to examine the mechanisms driving native plant recruitment, along with an assessment of flora–fauna interaction networks, particularly native plant interactions with invasive weeds, rats and chickens on Norfolk Island. It will identify and quantify key threats and barriers to recruitment of native plant species.
Protecting threatened quolls and other biodiversity on Kimberley islands from cane toads

Protecting threatened quolls and other biodiversity on Kimberley islands from cane toads

4.2.5
This research will use existing data to predict future invasion by cane toads of Australian islands, particularly the Kimberley islands. This information is important for prioritizing surveillance action on these islands in order to conserve toad-sensitive species such as the endangered Northern Quoll.
Threatened plant translocations

Threatened plant translocations

4.3
Translocations are being increasingly used in threatened plant recovery programs. The outcomes of past translocation programs have often been poorly documented or unpublished. This makes it hard to learn from the past experiences, to adapt and improve techniques in response to outcomes or to determine if investments have been worthwhile.
Identifying and managing refuges from threats

Identifying and managing refuges from threats

4.4
Refuges are important to many species, as they allow many species to survive environmentally stressful times, like droughts, fires and disease outbreaks. While fixed refuges like mountain tops can be easy to identify, many species rely on temporary refuges which move in time and space.

A national approach to the integration of koala spatial data to inform conservation planning

4.4.12
The koala populations of New South Wales, Queensland and the Australian Capital Territory are listed as threatened under the EPBC Act. This project will work with these jurisdictions to ensure the national recovery plan for koalas aligns with state/territory strategies, plans and legislation, with the outcome of a coordinated and collaborative national approach to koala conservation.
