“…The first of these includes a variety of stoat and weasel species often introduced for the purposes of pest control-sometimes as a misguided response to problems caused by introduced rodents (Uchida 1968;Uesugi et al 1998). Introduced Diprotodontia include a number of translocations to offshore islands for the purposes of conservation, again largely in response to problems caused by other introduced species (Langford and Burbidge 2001;Miller et al 2011), but also introductions for food (e.g. P. orientalis mentioned above), fur (Trichosurus vulpecula to New Zealand) and through escapes from private collections (e.g., Macropus rufogriseus in the UK) (Long 2003).…”

Humans have an extremely long history of transporting and introducing mammal species outside their native geographic ranges. The characteristics of the species introduced (taxonomy, life-history, ecology, environment) can all influence which traits are available (and selected) for establishment, and subsequent invasive spread. Understanding the non-randomness in species introductions is therefore key to understanding invasions by alien species. Here, we test for selectivity in the identities and traits of mammal species introduced worldwide. We compiled and analysed a comprehensive database of introduced mammal species, including information on a broad range of life history, ecological, distributional and environmental variables that we predicted to differ between introduced and non-introduced mammal species. Certain mammal taxa are much more likely to have been introduced than expected, such as Artiodactyls in the families Bovidae and Cervidae. Rodents and bats were much less likely to have been introduced than expected. Introduced mammal species have significantly larger body masses, longer lifespans and larger litter sizes than a random sample of all mammal species. They also have much larger native geographic ranges than expected, originate from significantly further north, from cooler areas, and from areas with higher human population densities, than mammal species with no recorded introductions. The traits and distributions of species help determine which have been introduced, and reflect how the evolutionary history of mammals has resulted in certain species with certain traits being located in the way of human histories of movement and demands for goods and services. The large amount of unexplained variation is likely to relate to the intrinsically stochastic nature of this human-driven process. Blackburn et al. / NeoBiota 33: 33-51 (2017) 34

“…Rufous Hare-wallaby (RHW; central Australian subspecies) males weigh from 0.8 to 1.6 kg, slightly heavier than females (0.9-1.3 kg) (Johnson & Burbidge 1998). Their distribution and behaviour are described in Langford and Burbidge (2001) and Hardman and Moro (2006a). Banded Hare-wallabies (BHW) weigh up to 2.1 kg (Prince 1998).…”

Summary As evidence mounts that the feral Cat (Felis catus) is a significant threat to endemic Australian biodiversity and impedes reintroduction attempts, uncertainty remains about the impact a residual population of cats following control will have on a mammal reintroduction programme. Also, behavioural interactions between cats and their prey continue to be an area of interest. Within the framework of an ecosystem restoration project, we tested the hypotheses that successful reintroductions of some medium‐sized mammals are possible in locations where feral cats are controlled (but not eradicated) in the absence of European Red Fox (Vulpes vulpes), and that hare‐wallabies that dispersed from their release area are more vulnerable to cat predation compared with those that remain at the release site. We used radiotelemetry to monitor the survivorship and dispersal of 16 Rufous Hare‐wallabies (Lagorchestes hirsutus spp.) and 18 Banded Hare‐wallabies (Lagostrophus fasciatus fasciatus) reintroduced to four sites within Shark Bay, Western Australia. Nearly all foxes were removed and feral cats were subject to ongoing control that kept their indices low relative to prerelease levels. All monitored hare‐wallabies were killed by cats within eight and 10 months following release. Significant predation by feral cats was not immediate: most kills occurred in clusters, with periods of several months where no mortalities occurred. Once a hare‐wallaby was killed, however, predation continued until each population was eliminated. Animals remaining near their release site survived longer than those that dispersed. The aetiology of predation events observed offers new insights into patterns of feral cat behaviour and mammal releases. We propose a hypothesis that these intense per capita predation events may reflect a targeted hunting behaviour in individual feral cats. Even where feral cats are controlled, the outcome from consistent predation events will result in reintroduction failures. Managers considering the reintroduction of medium‐sized mammals in the presence of feral cats should, irrespective of concurrent cat control, consider the low probability of success. We advocate alternative approaches to cat‐baiting alone for the recovery of cat‐vulnerable mammals such as hare‐wallabies.

Translocations have become an increasingly popular tool in threatened macropod conservation in Australia. Although previous evaluations of Australian macropod translocations have been published, the number of contemporary translocation programmes awaiting analysis, and new data regarding historic translocations, required a new assessment of macropod translocation programmes. We aimed to assess trends in the way macropod translocations were conducted during the period 1969–2006, determine the number of successful translocations and identify factors common to successful translocations. Data regarding macropod translocations were obtained from a wide variety of sources, including peer‐reviewed journals, ‘grey’ literature and popular interest publications. Questionnaires were also sent to translocation managers to acquire detailed information. Specific aspects of macropod translocation methodology were analysed, and classification tree analysis was conducted to identify methodological and environmental factors common to successful translocations. We identified 109 macropod translocations for which sufficient data could be collected to permit analysis. Using the presence of a population on 1 January 2007 as a simple criterion, 61% of translocations were successful. Of these translocations, 66% were also considered successful by Short et al.'s criteria (population persisted for five years and is deemed likely to continue to persist); the remainder could not be assessed due to lack of data or insufficient elapsed time since release. Classification tree analysis suggested methodological and environmental factors common to successful translocations; the overriding factor determining success was the absence of cats and foxes at the release site. Although Australian macropod translocation proponents are faced with myriad methodological options when designing a translocation protocol, the primary consideration should be whether or not cats or foxes are present at the release site. Managers should be aware that there may be no safe population level of such predators for some translocation candidate species. Ignoring this fact will inevitably lead to a repeat of past translocation failures.
