The rights-of-nature model is gaining traction as an innovative legal approach for nature conservation. Although adopted in several countries, it remains in its infancy, including in Australia. An important research question is whether rights of nature will offer superior environmental outcomes compared to traditional nature conservation techniques including creation of protected areas. This article investigates that question through a case study of the Tarkine wilderness, in the Australia state of Tasmania. It first identifies key lessons from existing international experience with affirmation of rights of nature, such as in New Zealand and Ecuador. The article then explores how rights of nature could apply in Australia’s Tarkine region and their value compared to existing or potential protected areas and other nature conservation measures under Australian or Tasmanian law. Affirming rights of nature represents a major conceptual shift in how people via the law relate to the natural world, but whether the model offers practical benefits for nature conservation depends on a variety of conditions, in addition to the need to address broader societal drivers of environmentaldegradation.

With ever-increasing demands being made on remote and natural lands, planners and managers require more detailed information than hitherto to assist them in monitoring the status of this wilderness resource and developing appropriate and effective management prescriptions. These requirements are addressed by a computer-based wilderness evaluation procedure that has been developed for a national wilderness survey of Australia.The methodology, based on the wilderness continuum concept (Lesslie & Taylor, 1985), places emphasis on measuring variation in wilderness quality by using four indicators that represent the two essential attributes of remoteness and naturalness. This permits a precise assessment to be made of the wilderness resource, revealing those factors which contribute to or compromise wilderness quality. The computer-based storage and analysis of data enables surveys to be conducted over large, even continental, areas, yet at a relatively fine level of resolution that is appropriate to localized planning needs.Trial application to the State of Victoria, Australia, demonstrates that the survey procedure can be successfully adapted to a wide range of environments, use-patterns, data-base characteristics, and management objectives, which should be applicable and very widely useful elsewhere.

ABSTRACTThe manner and extent to which birds associate with humans may influence the genetic attributes and antimicrobial resistance of their commensalEscherichiacommunities through strain transmission and altered selection pressures. In this study, we determined whether the distribution of the differentEscherichia coliphylogenetic groups and cryptic clades, the occurrence of 49 virulence associated genes, and/or the prevalence of resistance to 12 antimicrobials differed between four groups of birds from Australia with contrasting types of human association. We found that birds sampled in suburban and wilderness areas had similarEscherichiacommunities. TheEscherichiacommunities of backyard domestic poultry were phylogenetically distinct from theEscherichiacommunities sourced from all other birds, with a large proportion (46%) of poultry strains belonging to phylogenetic group A and a significant minority (17%) belonging to the cryptic clades. Wild birds sampled from veterinary and wildlife rehabilitation centers (in-care birds) carriedEscherichiaisolates that possessed particular virulence-associated genes more often thanEscherichiaisolates from birds sampled in suburban and wilderness areas. TheEscherichiaisolates from both the backyard poultry and in-care birds were more likely to be multidrug resistant than theEscherichiaisolates from wild birds. We also detected a multidrug-resistantE. colistrain circulating in a wildlife rehabilitation center, reinforcing the importance of adequate hygiene practices when handling and caring for wildlife. We suggest that the relatively high frequency of antimicrobial resistance in the in-care birds and backyard poultry is due primarily to the use of antimicrobials in these animals, and we recommend that the treatment protocols used for these birds be reviewed.

An aerial survey along a transect from eastern side of the Arnhem Land Plateau where Aboriginal people still lead a semi-traditional lifestyle, to the unoccupied western side of the Plateau, revealed systematic differences in the proportion of living and dead Callitris intratropica trees. Multiple regression analysis showed that the highest proportion of dead C. intratropica stems occurred on unoccupied, level terrain dominated by open Eucalyptus forests, with a minor or complete absence of Allosyncarpia ternata closed-canopy forests. A detailed study of one population of C. intratropica in western Arnhem Land adjacent to a small patch of A. ternata forest, known as Round Jungle, showed that the population had a unimodal size-class distribution, reflecting a low density of stems less than 10 cm in diameter at breast height (dbh). A computer simulation model was developed on the basis of estimates of annual fecundity, mortality and growth rates derived from observations of the stand. Sensitivity analyses suggested that a well-stocked stand could be transformed to one similar to that observed at Round Jungle after 50 years, if annual mortality rate of the immature stems (i.e. <12 cm dbh) was greater than 85%. Under these conditions, the stand would become extinct after 325 years. Variation in estimates of mature-stem (>12 cm dbh) mortality and fecundity had much less effect on the predictions of the model than the rate of mortality of the smallest size class. The model suggests that C. intratropica populations can rapidly fluctuate in response to changes in fire regime, while extinction is a gradual process and is consequently unlikely if some seedlings can escape burning, for instance by establishing in fire-protected microsites. This conclusion is consistent with the observed greater mortality of C. intratropica on sand sheets that have little topographic variability at the micro- or mesoscale, compared with other habitat types in areas that are currently unoccupied by Aboriginal people. Our study shows that predicting the fate of individual populations will require careful consideration of local factors such as the presence of micro-topographically safe sites for seedling establishment, as well as the surrounding pattern of vegetation and landforms that mediate the impact of fire on C. intratropica. However, we suggest that rather than refining details of the adjustment of C. intratropica in response to changed fire regimes associated with European colonisation, subsequent research should focus on the effect and significance of these changes for other organisms.

Context Since the introduction of fallow deer (Dama dama) to Tasmania in the early 1830s, the management of the species has been conflicted; the species is partially protected as a recreational hunting resource, yet simultaneously recognised as an invasive species because of its environmental impact and the biosecurity risk that it poses. The range and abundance of fallow deer in Tasmania has evidently increased over the past three decades. In the 1970s, it was estimated that ~7000–8000 deer were distributed in three distinct subpopulations occupying a region of ~400 000 ha (generally centred around the original introduction sites). By the early 2000s, the estimated population size had more than tripled to ~20 000–30 000 deer occupying 2.1 million ha. No study has attempted to predict what further growth in this population is likely. Aims The purpose of our study was to provide a preliminary estimate of the future population range and abundance of fallow deer in Tasmania under different management scenarios. Methods We developed a spatially explicit, deterministic population model for fallow deer in Tasmania, based on estimates of demographic parameters linked to a species distribution model. Spatial variation in abundance was incorporated into the model by setting carrying capacity as a function of climate suitability. Key results On the basis of a conservative estimate of population growth for the species, and without active management beyond the current policy of hunting and crop protection permits, abundance of fallow deer is estimated to increase substantially in the next 10 years. Uncontrolled, the population could exceed 1 million animals by the middle of the 21st century. This potential increase is a function both of local increase in abundance and extension of range. Conclusions Our results identify areas at high risk of impact from fallow deer in the near future, including ecologically sensitive areas of Tasmania (e.g. the Tasmanian Wilderness World Heritage Area). Implications The research approach and results are presented as a contribution to debate and decisions about the management of fallow deer in Tasmania. In particular, they provide a considered basis for anticipating future impacts of deer in Tasmania and prioritising management to mitigate impact in ecologically sensitive areas.

Natural area tourism may contribute to deterioration in biophysical environments important for sustainable conservation of biodiversity and/or historically significant sites. Levels of protection within the IUCN guidelines provide general descriptors of desirable outcomes, and the Limits of Acceptable Change (LAC) management tool has often been implicitly applied. This article presents an initial attempt to assess the value of Thresholds of Potential Concern (TPC) relative to LAC as management frameworks for protected areas, using the example of trail width as an indicator of visitor impacts on vegetation, soil, water and, potentially, visitor safety. Visitor preferences relating to trail width were incorporated when applying the TPC and LAC principles. Sections of three walking trails in a high-visitation national park near Sydney, Australia, were measured at ~10.7 m intervals: the mean trail widths were 1.6 m, 1.8 m and 2.14 m. Of the 115 recreationists surveyed, 16% of those having the greatest tolerance towards management interventions (‘Non-purist’ wilderness category) viewed a trail ≥ 2 m wide as acceptable, but 96% of ‘Purists’ nominated a maximum of ≤1.5 m. The TPC was found to provide a broad strategy for identification, assessment and grading of multiple biophysical thresholds within an ecological framework. Combined with stakeholder information, the TPC allows for timely, proactive and calibrated management responses to maintaining biophysical and social sustainability.

Introduction:Beginning Education at Central Coast Hospitals (BEACCHEs) was developed as an experiential wilderness experience to assist with student exposure to new hazards when commencing at a coastal regional hospital. The coast has several hazards which are specific to the area.Aim:To provide students with first responder education for situations commonly encountered on the Central Coast.Methods:Sessions on first responder training specific to coastal and remote locations included: first aid and surf safety with the Ocean Beach Surf-Lifesaving Club and anti-venom education with the Australian Reptile Park. Education was provided regarding the transition from academic to clinical medicine including support and workload management. A two-day workshop was held on the Central Coast. Pre- and post-workshop surveys were conducted with a combination of matrix questions, Likert response scales, and long answer questions. Ethics was obtained. Both quantitative and qualitative responses were analyzed.Results:Excellent feedback regarding this program was received. All students reported an increase in knowledge in all three domains of critical medicine and evacuation issues, student health and workload management, and Central Coast community and environment. The areas of greatest knowledge in each of these domains were the management of surf incidents, signs and symptoms of PTSD, and Central Coast marine and ocean environment. A confidence increase was seen in responding effectively to an emergency, particularly, in response to improvisation in the field. All findings were statistically significant with all P-values <0.01.Discussion:The addition of BEACCHEs to the orientation of medical students at the Central Coast Medical School has demonstrated to be an effective program for allowing students to adjust more quickly to the new clinical environment. Following the success of this program, BEACCHEs is expected to become part of the new Junior Medical Officer orientation in 2019.

In Sri Lanka, there are 31 species of bats distributed from lowlands to mountains. To document bat diversity and their habitat associations, 58 roosting sites in Maduru-Oya National Park periphery were surveyed. Fifteen bat species were recorded occupying 16 different roosting sites in this area. Among all the species recorded, Rhinolophusrouxii was the most abundant species per roosting site whereas Kerivoulapicta was the least abundant. A road-kill specimen similar to genus Phoniscus was found during the survey, a genus so far only documented in Southeast Asia and Australasia. Although our study area provided habitats for a diverse chiropteran community, the colony size per roost was remarkably low. Although our study area is supposedly a part of the park’s buffer zone, many anthropogenic activities are threatening the bat community: felling large trees, slash-and-burn agriculture, excessive use of agrochemicals, vengeful killing, and subsidized predation. We strongly recommend adoption of wildlife-friendly sustainable land management practices in the buffer zone such as forest gardening, agroforestry (alley cropping, mixed-cropping), and integrated farming. Bat conservation in this region should take a landscape-scale conservation approach which includes Maduru-Oya National Park and other surrounding protected areas into a regional conservation network. Extents of undisturbed wilderness are dramatically declining in Sri Lanka; thus, future conservation efforts must be retrofitted into anthropocentric multiuse landscapes and novel ecosystems like areas surrounding Maduru-Oya National Park.

Introduction:Best practice first aid management of accidental hypothermia and cold injuries in the prehospital setting is relevant for disaster management in cold environments as well as for wilderness and expedition medicine, and space medicine. In the Australasian context, guidance is currently taken from the Australian Resuscitation Council (“ARC”) Guidelines dealing with these issues.Aim:To review and update the recommendations of the ARC Guideline 9.3.3 Hypothermia: First-Aid Management (February 2009) and ARC Guideline 9.3.6 Cold Injury (March 2000).Method: The review is being undertaken through a combination of a focused literature review and expert opinion. Through the author’s membership of the International Commission for Alpine Rescue (“ICAR”) Alpine Emergency Medicine Commission, two northern-hemisphere experts on hypothermia have reviewed the guidelines and provided commentary and recommendations.Results:Much of the literature around accidental hypothermia and cold injuries (including frostbite, frostnip, and chilblains), relies on expert opinion and case studies. There are relatively few randomized controlled trials, and these are often confined to the laboratory setting. As a result, there is a heavier reliance on expert opinion than in any other areas of medicine.Discussion:This presentation will summarize the current best practice recommendations for the first aid management of accidental hypothermia and cold injuries through combining the existing ARC Guidelines with key advances identified through the literature review, and the key management recommendations stemming from expert opinion. This will provide attendees with a cohesive set of clinical practice recommendations which can be used in the field.

Throughout history the city and the wilderness have been both idea and environment for urban man. The conflict between them is expressed in the earliest mythology and manifest today in the conservation versus development debate. The conflict is misdirected: conservation and development are interdependent. They are the same process on different time scales: the sustainance and security of life on earth. Their reconciliation is proposed in the concept of sustainable development.The widespread concern about the environment in the industrialised, developed societies today combines scientific and emotional components. The scientific component is a new and valuable appreciation of, and commitment to, the global ecology. The emotional component is more an anti-technology mood, an historically cyclic phenomenon of complex origins. Modern environmentalism is a complex amalgamation of those environmental concerns with wide ranging socio-economic and political reforms. Those reforms frequently involve the concept of no-growth or very limited economic growth, especially in Western industrial society, and derive from a pessimistic world view historically common among intellectuals. It is environmentalism, not conservationism, which is in conflict with the concept of development.A successful petroleum industry is vital to Australia's future security and welfare. The main threat to the industry comes from environmentalism, and the confusing myriad of legislation and regulation it has sponsored. Of particular significance is the policy of excluding exploration from conservation areas, rather than adopting a multiple and sequential land use approach. The single-usage approach to land management is inefficient balancing of resources and, correspondingly, is poor conservation practice. Multiple land use is a fundamental tenet of the sustainable development and the National Conservation Strategy of Australia.APEA, and business and industry generally, must improve communications with the public. The significance of primary resources in the daily life and national economy must be retaught. Industry must play a leading role in defining and implementing sustainable development, and in championing the concept. The concept will be attacked and manipulated by no-growth environmentalists, but they must not be allowed to prevail.Sustainable development offers the present generations the chance to reconcile conservation and development. That reconciliation is an imperative for the future.

The disruption of natural fire regimes has threatened animal species in many ecosystems around the world. A combination of prescribed burning and fire suppression is often used to promote successional variation in vegetation (i.e. fire mosaics), with little knowledge of how this will affect animal persistence. Understanding the processes that govern species responses to fire regimes is essential to build a predictive capacity for ecological fire management. I examined life-history, demographic (survival, reproduction and mortality) and dispersal attributes of reptiles to investigate mechanisms of fire responses in reptiles. I studied reptiles in conservation reserves of semi-arid southern Australia dominated by mallee vegetation (multi-stemmed Eucalyptus spp. with a shrubby understory). An introduction describes the ecological and management context of my research (Chapter 1). A community-level framework was used to determine if a generalised model of fire responses could be developed based on traits shared by groups of species (Chapters 2-3). I found a number of fire responses in reptiles that were previously undetected in analyses of smaller, but substantial subsets of the same data (Chapter 2). Nocturnal burrowers tended to be early-successional, while diurnal leaf-litter dwellers tended to be late successional, but a trait-based model of succession had limited power to describe responses among the community. I also documented some observations that suggested non-burrowing reptiles were more vulnerable to mortality during wildfire than burrowers (Chapter 3). A species-level framework was then used to examine variation in demographic and dispersal attributes within species among different post-fire successional stages (Chapters 4-7). These studies focussed on three species with significant and contrasting responses to fire: Amphibolurus norrisi (Agamidae; mid/late successional species), Ctenotus atlas (Scincidae; late successional) and Nephrurus stellatus (Gekkonidae; early/mid successional).
Using mark-recapture modelling (Chapter 4), I described changes in abundance of N. stellatus that incorporated detectability, and showed that variation in survival and fecundity are possible drivers of this species strong population response to fire. Microsatellite DNA data were then used to examine gene flow in the three target species and gain insights into the effects of fire on dispersal. Chapter 5 begins this section with a description of the markers I used to generate the genetic data. I then used spatial models of landscape resistance to assess the importance of post-fire succession and other landscape features (e.g. topography) on gene flow in the three species (Chapters 6 and 7). For N. stellatus these analyses were combined with direct observations of movement (Chapter 6). Results showed that long-unburnt vegetation restricts dispersal in N. stellatus, which may result from, or contribute to its decline in population density with increasing time since fire. In Chapter 7 I found that fire affected gene flow in A. norrisi, but not in C. atlas, while genetic diversity in both species was affected by post-fire succession.
My thesis demonstrated how examining demographic and dispersal attributes of reptiles can give insights into the mechanisms underlying species responses to fire. I concluded by providing management recommendations and highlighting key points for future research on fire ecology (Chapter 8). -- provided by Candidate.
