Bandicoots (Perameles gunnii, Isodon obesulus)

​Application for Scientific Permit – Available for Public Comment

Public comment on the following application for a Scientific Research (Fauna) Permit is open until 4 September.

Applicant: Murdoch University

Species/Taxon: Eastern barred Bandicoot (Perameles gunnii), Southern brown bandicoot (Isoodon obesulus)

Location: Various locations in Tasmania, including private land, crown land and reserves.

Title of research: Development of a framework for the assessment of the health of wild bandicoot populations.

Aim of project:
This project’s definitive goal is to develop a comprehensive framework to assess the health of wild bandicoot populations. To achieve this, the following goals will be met in relation to populations of wild bandicoots in Tasmania: (1) measurement and assessment of a wide range of individual health/disease parameters; (2) collection of demographic data ; (3) assessment of genetic diversity; (4) development and use of innovative monitoring methods using remote microchip readers at baited stations, to investigate longevity and long-term movements;(4) investigation of mortality & morbidity associated with various conditions affecting wild platypuses.

Justification:
There are a range of changes that are known to occur during population declines. These include changes to demographic factors such as age/sex structure and geographic distribution, as well as genetic diversity and disease prevalence.  Our population health assessment framework aims to be a structured way of looking at a broad range of population characteristics concurrently, and may improve the sensitivity of population status monitoring.  This work will follow and parallel successful health and conservation work completed in one other species to date.  We intend to undertake projects developing similar population health assessment frameworks for other species of wildlife, to allow better interpretation of results and improved conservation management outcomes.  This project will update knowledge relating to the health of bandicoots in Tasmania, and address key gaps in knowledge of bandicoot population health including (1) morbidity and mortality rates associated with the various conditions affecting bandicoots; (2) population dynamics, including longevity, migration and juvenile recruitment rates; (3) the immunogenetic diversity of populations;and (4) the relationship between environmental factors (such as land use and habitat disturbance) and disease.  A range of habitat types will be selected for fieldwork, which may require some fieldwork to be performed in reserves.

Activities undertaken and methods:
Animals will be captured using baited cage traps.  Captured bandicoots will be examined under isofluorane anaesthesia.  Body measurements will be taken.  The following samples will be taken for laboratory testing: blood, skin notch from an ear, rectal swab, urine, external parasites, as well as punch biopsies, fine needle aspirates, biopsies and swabs from skin lesions. Bandicoots will be individually identified with a microchip and release at the site of their capture after being held for no more than 4 hours.  All individuals of bycatch species will be released immediately.  Remote microchip readers will be used at baited stations to monitor the movements and survivorship of microchipped bandicoots.

Fate of animals: All animals will be released at the site of their capture

Likely impact on species involved (including any by-catch):
There is likely to be no impact on species involved; no individuals will be removed from their natural environment and all individuals will be released at the site of their capture.
