4.2 Recovery objectives and performance criteria

This Recovery Plan guides the recovery of the threatened western barred bandicoot, burrowing bettong and banded hare-wallaby, for 10 years or until this plan is replaced.



Long term recovery objectives
The long term objective of the recovery program is to undertake conservation actions which:

Ensure the survival and maintain or improve the status of the western barred bandicoot and Bernier and Dorre Island subspecies of the burrowing bettong and banded hare-wallaby and Barrow Island subspecies of the burrowing bettong based on the IUCN criteria 2001 extent of occurrence*.


* Extent of occurrence is defined as the area contained within the shortest continuous imaginary boundary which can be drawn to encompass all the known, inferred or projected sites of present occurrence of a taxon, excluding cases of vagrancy. This measure may exclude discontinuities or disjunctions within the overall distributions of taxa (e.g. large areas of obviously unsuitable habitat). Extent of occurrence can often be measured by a minimum convex polygon (the smallest polygon in which no internal angle exceeds 180 degrees and which contains all the sites of occurrence) (IUCN, 2001).


The downgrading of the status of these three species to anything less threatened than ‘Vulnerable’ is unlikely within the next ten years, due to the inability to implement broadscale control of the primary threat of introduced predators on mainland Australia.
There are five primary strategies recognised for the recovery of the western barred bandicoot, burrowing bettong and banded hare-wallaby:

  1. Maintenance of wild populations;

  2. captive breeding and reintroduction;

  3. threat abatement;

  4. community involvement and education;

  5. Recovery team to manage recovery actions

The success of the recovery plan will be measured through assessing whether the recovery actions have been successful in achieving the primary objectives.

Criteria for success:


  • population estimates calculated from a five year moving average for each species on Bernier, Dorre, Barrow and Boodie Islands, do not fall below the minimum figure (Illustrated in Figure 5 this would be approximately 1000 for each species);

  • within ten years translocations to at least 3 new mainland or island sites have been established for each species.

Criteria for failure:



  • The population estimate calculated from a five year moving average for any species on any island falls below the minimum figure (Illustrated in Figure 5 this would be approximately 1000 for each species);

  • less than three introduced mainland or island translocations are established within ten years for each species.

For each recovery action, performance evaluation is regarded as the responsibility of the primary organisation involved in that recovery action and the Recovery Team.




4.3. Recovery actions


The recovery team for the western barred bandicoot, burrowing bettong and banded hare-wallaby is currently managed by DEC. Annual meetings are held to evaluate the progress of the Recovery Plan, and to modify recovery actions where necessary. These are organised by DEC, with participation from DEC, AWC, ARP, ULCBPG, DENR and other organisations as appropriate.

Action 1: Protect the wild populations and their habitat



This action includes:

a) Manage and monitor populations on Bernier and Dorre Islands, Faure Island, Boodie Island and Barrow Island Nature Reserve.

Tasks:

  • protecting from threats such as: biosecurity incursions, foxes, cats and fire


  • implementing the disease risk management strategy (Chapman et al. 2008)

  • include a management strategy to address the disease risk to fauna by members of the public visiting Bernier and Dorre Islands

These tasks will be undertaken in accordance with the Shark Bay Terrestrial Reserves Management Plan 2000 – 2009 (Hancock et al. 2000) and Barrow Island Nature Reserve Interim Management Guidelines (CALM 1999a).



b) Developing and implementing a cost-effective monitoring program for the wild island populations.

Tasks:


  • Implement monitoring protocol includes:

    • monitor island populations yearly,

    • checking for signs of disease and condition,

    • use baseline data as reference for ‘early warning’ thresholds to indicate where population declines may be cause for concern and developing management actions should such an occasion arise

  • report annually to the Recovery Team to facilitate adaptive management of the populations and their habitat

  • incorporate recommendations into recovery actions to manage re-introduced populations and to re-introduce species to new sites.

Responsibility: DEC, Recovery Team

Cost: $8,000

Priority: Medium



b) Ensure the publication of results of research into the taxonomic status and genetic structure of burrowing bettong populations.
