Environmental Risk Assessment - Impact of the introduction of Tasmanian devils to Maria Island on the natural values of the island

  title={Environmental Risk Assessment - Impact of the introduction of Tasmanian devils to Maria Island on the natural values of the island},
  author={Menna E. Jones and Hamish I McCallum},
A proposal to introduce Tasmanian devils (Sarcophilus harrisii) to Maria Island, off the east coast of Tasmania, is under consideration by the Steering Committee of the Devil Facial Tumour Disease Program (Department of Primary Industries and Water DPIW). The proposal is to translocate up to 50 juvenile devils from the West Coast of Tasmania to Maria Island, following disease risk reduction protocols. The disease has yet to reach the West Coast, but is spreading at a variable rate of… Expand
Translocation of a top-order carnivore: tracking the initial survival, spatial movement, home-range establishment and habitat use of Tasmanian devils on Maria Island
Initial research indicates that translocation as a management action is a powerful tool for the establishment of ex situ populations, assisting in the continued conservation of this species. Expand
Translocation of a top-order carnivore: tracking the initial survival, spatial movement, home-range establishment and habitat use of Tasmanian devils on Maria Island
The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial threatened with extinction from the emergence of Devil Facial Tumour Disease. The establishment of ex situ populations is a keyExpand
Pedigree reconstruction using molecular data reveals an early warning sign of gene diversity loss in an island population of Tasmanian devils (Sarcophilus harrisii)
This study reconstructs the pedigree of 86 island-born devils using 31 polymorphic microsatellite loci and highlights the value of combining pedigree analyses with molecular data, from both a single-site and metapopulation viewpoint, for analysing changes in genetic parameters within populations of conservation concern.

Temporal partitioning of activity: rising and falling top‐predator abundance triggers community‐wide shifts in diel activity
The rapid changes in devil abundance provide a unique framework to test how the non-lethal effects of top predators affect community-wide partitioning of temporal niches, revealing that this top predator has an important but varied influence on the diel activity of other species. Expand


Tasmania's Threatened Fauna Handbook: What, Where and How to Protect Tasmania's Threatened Animals
Australia already has a long list of native species that have become extinct since the arrival of humans in this country, but ongoing clearing, degradation and replacement of native vegetation combined with the invasion of exotic species threatens the survival of endemic flora and fauna. Expand
Obsevations on the Tasmanian Devil, Sarcophilus harrisii (Marsupialia : Dasyuridae) I. Numbers, home, range, movements and food in two populations
Females were more numerous in all populations but a heavier mortality of this sex occurs in late life in one population, and juvenile recruitment was greater in areas with less food than in areas of abundant food, due to the absence of overcrowding. Expand
Past and Present Distribution of the Eastern Barred Bandicoot (Perameles gunnii) in the Midlands, Tasmania
Evidence is presented that the removal of >80% of the original Midlands native vegetation through clearing for agriculture and stock-grazing is suggested as the principal cause of this decline of the Eastern Barred Bandicoot in Tasmania. Expand
Habitat Requirements of the Eastern Barred Bandicoot, Perameles gunnii, on Agricultural Land in Tasmania
It is hypothesised that the remnant populations of P. gunnii found in the Midlands reflect the availability of pockets of suitable habitat, in particular the presence of significant ground cover for nesting sites and refugia. Expand
Distribution records of native terrestrial mammals in Tasmania
The distributions of 34 species of terrestrial mammals native to Tasmania are presented as presence/ absence records on 10 x 10 km grid maps and notes on the ease of recording species and their habitats are provided to supplement and assist the interpretation of their distributions. Expand
Mammal invaders on islands: impact, control and control impact
It is difficult to predict the outcome of the removal of key species, such as a top predator, given the numerous and complex population interactions among island species, and justifies careful pre‐control study and preparation prior to initiating the eradication of an alien species, in order to avoid an ecological catastrophe.

Defining 'Evolutionarily Significant Units' for conservation.

  • Trends in ecology & evolution
  • 1994
With the explicit recognition of the genetic component of biodiversity in conservation legislation of many countries and in the Convention on Biological Diversity, the ESU concept is set to become increasingly significant for conservation of natural as well as captive populations. Expand
Distribution, habitat characteristics and conservation requirements of a forest-dependent threatened invertebrate Lissotes latidens (Coleoptera: Lucanidae)
The distribution, habitat and conservation requirements of an endangered stag beetle, Lissotes latidens, in south-east Tasmania were investigated and recommendations are made for the conservation management of habitat utilised by L.latidens in ‘off-reserve’ areas. Expand
Coevolution in phenotype among predators and prey and consequent constraint on performance in different habitat types were the most easily measured explanations for habitat differentiation among these species, particularly between spotted-tailed quolls and devils. Expand
Comparison of helicopter line transects with walked line transects for estimating densities of kangaroos
Density estimates obtained from the helicopter surveys were not significantly different from those obtained from ground surveys for both red and eastern grey kangaroos as assessed by repeated-measures ANOVA and regression analysis. Expand
