Potential threats and habitat of the night parrot on the Ngururrpa Indigenous Protected Area

Context The Endangered night parrot (Pezoporus occidentalis) is one of the rarest birds in Australia, with fewer than 20 known to occur in Queensland and, prior to 2020, only occasional detections from a handful of sites in Western Australia (WA). Here, we provide an introduction to night parrots on the Ngururrpa Indigenous Protected Area (IPA) in WA from the perspectives of both Indigenous rangers and scientists working together to understand their ecology. Aims We aimed to identify night parrot sites on the Ngururrpa IPA, compare habitat and likely threats with those in Queensland and identify appropriate management practices. Methods Between 2020 and 2023, we used songmeters (a type of acoustic recorder) to survey for the presence of night parrots at 31 sites (>2 km apart). At sites where parrots were detected, we used camera-traps to survey predators and collected predator scats for dietary analysis. Forty years of Landsat images were examined to assess the threat of fire to roosting habitat. Key results Night parrots were detected at 17 of the 31 sites surveyed on the Ngururrpa IPA. Positive detections were within an area that spanned 160 km from north to south and 90 km from east to west. Ten roosting areas were identified, and these occurred in habitat supporting the same species of spinifex (lanu lanu or bull spinifex, Triodia longiceps) used for roosting in Queensland. However, the surrounding landscapes differ in their vegetation types and inherent flammability, indicating that fire is likely to be a more significant threat to night parrots in the Great Sandy Desert than in Queensland. Dingoes (Canis dingo) were the predator species detected most frequently in night parrot roosting habitat and the feral cat was found to be a staple prey for dingoes at night parrot sites. Conclusions Our surveys indicated that there could be at least 50 night parrots on the Ngururrpa IPA, which is the largest known population in the world. Fire is a key threat to roosting habitat, occurring in the surrounding sandplain country every 6–10 years. Dingoes are common in night parrot habitat and regularly eat feral cats, which are only occasionally detected in roosting habitat. Implications We recommend management that focuses on strategic burning to reduce fuel loads in the surrounding landscape, and limiting predator control to methods that do not harm dingoes.

A summary framework for effective engagement of IPLCs and rangers

In this paper we focus on the pressing need to effectively engage with Indigenous Peoples and Local Communities (IPLCs) and the need to strengthen the capacity of rangers originating from these communities. Opportunities for full participation and leadership by IPLCs are improved by enhancing the role of Indigenous and local rangers in fostering relationships while integrating cultural knowledge into the work on the ground. This also strengthens local benefits. We emphasize the invaluable contribution of IPLCs to conservation, often honed over generations, and explore current models of partnership and engagement. Particularly, we spotlight the vital role of IPLC rangers, who leverage unique skills, local knowledge, and cultural practices in their conservation work. The roles of both IPLCs and local Indigenous rangers are essential if we are to meet our goals for conserving 30% of the earth’s lands and waters by 2030 as promoted at the COP15 meeting of the Convention on Biological Diversity (CBD), achieve the objectives for development of IPLC rangers as stated of Chitwan Declaration of 2019 (CD), or meet the related targets set by the Universal Ranger Support Alliance (URSA). We advocate for a partnership model with IPLCs that applies the principles of Collective Impact to improve outcomes and secure enduring benefits at all levels. To aid stakeholders in conservation projects involving IPLCs (including governments, businesses, and non-governmental organizations), we propose a straightforward summary framework that outlines stages for the development of relationships and projects. It integrates the work of others, including foundation principles, management systems for partnerships, and good practices, and stresses the need for pre-project training, learning and other forms of preparation. Altogether, these principles and accompanying recommendations help lay the groundwork for effective intergenerational projects involving IPLCs with long-term benefits.

Building meaningful collaboration in conservation genetics and genomics

AbstractGenetic diversity is the foundation of biodiversity, and preserving it is therefore fundamental to conservation practice. However, global conservation efforts face significant challenges integrating genetic and genomic approaches into applied management and policy. As collaborative partnerships are increasingly recognized as key components of successful conservation efforts, we explore their role and relevance in the Australian context, by engaging with key entities from across the conservation sector, including academia, botanic gardens, herbaria, seed banks, governmental/non-governmental organisations, private industry, museums, Traditional Owners, Indigenous rangers, and zoos and aquaria. By combining perspectives from these entities with comprehensive literature review, we identified five guiding principles for conservation genetic and genomic research and explored the different elements of, and approaches to, collaboration. Our reflections suggest that there is a substantial overlap in research interests across the Australian conservation sector, and our findings show that collaboration is increasing. We discuss approaches to building collaborative partnerships, the reciprocal benefits of collaborating, and some remaining challenges associated with data generation, data collection, and cross-cultural considerations. We emphasise the need for long-term national resourcing for sample and data storage and consistency in collecting, generating and reporting genetic data. While informed by the Australian experience, our goal is to support researchers and practitioners to foster meaningful collaborations that achieve measurable management outcomes in conservation genetics and genomics, both in Australia and globally.

Extant and extinct bilby genomes combined with Indigenous knowledge improve conservation of a unique Australian marsupial

Ninu (greater bilby, Macrotis lagotis) are desert-dwelling, culturally and ecologically important marsupials. In collaboration with Indigenous rangers and conservation managers, we generated the Ninu chromosome-level genome assembly (3.66 Gbp) and genome sequences for the extinct Yallara (lesser bilby, Macrotis leucura). We developed and tested a scat single-nucleotide polymorphism panel to inform current and future conservation actions, undertake ecological assessments and improve our understanding of Ninu genetic diversity in managed and wild populations. We also assessed the beneficial impact of translocations in the metapopulation (N = 363 Ninu). Resequenced genomes (temperate Ninu, 6; semi-arid Ninu, 6; and Yallara, 4) revealed two major population crashes during global cooling events for both species and differences in Ninu genes involved in anatomical and metabolic pathways. Despite their 45-year captive history, Ninu have fewer long runs of homozygosity than other larger mammals, which may be attributable to their boom–bust life history. Here we investigated the unique Ninu biology using 12 tissue transcriptomes revealing expression of all 115 conserved eutherian chorioallantoic placentation genes in the uterus, an XY1Y2 sex chromosome system and olfactory receptor gene expansions. Together, we demonstrate the holistic value of genomics in improving key conservation actions, understanding unique biological traits and developing tools for Indigenous rangers to monitor remote wild populations.

Current and emerging feral cat management practices in Australia

Context Feral cats are responsible for the decline and extinction of species globally. Predation by feral cats is identified in Australian legislation as a key threatening process. However, clear guidance to local land managers on feral cat management techniques and their impacts, limitations and potential costs can be difficult to find. Aims In this study, feral cat management experts from around Australia identified available management techniques and their average environmental, social, and economic impact for different ecoregions and land-use types. Methods We convened a 1-day structured elicitation workshop with 19 experts and five facilitators. Experts identified the techniques used for feral cat management; the effectiveness, impact, and cost of each method; and the key knowledge gaps associated with feral cat management. Facilitators aided in the design and format of the workshop, led the discussion at each stage and collated the results. Key results Experts identified the following 10 techniques currently used in Australia: aerial baiting; ground baiting; leghold trapping; cage trapping; shooting; tracking with detector dogs; tracking by Indigenous Rangers; habitat modification; resource modification; and exclusion fencing. In general, experts highlighted that permits, legislation and scale of application constrained many of these techniques. Aerial baiting was considered the most effective technique for reducing feral cat populations in natural and production systems. Cage trapping, shooting, or tracking with detector dogs were considered more effective in residential areas. For all techniques, efficacy estimates varied according to the following three broad vegetation structural regions: (1) deserts and xeric shrublands; (2) forests and woodlands; and (3) grasslands, savannas and shrublands. Techniques considered to have the lowest social tolerance and highest impact to non-target native species included aerial baiting, ground baiting and leghold trapping. Techniques considered to have high social tolerance and low impact on non-target species included tracking by Rangers, tracking with detector dogs, and habitat and resource modification. Conclusions Estimates of management action efficacy differ among land-use types and at least three vegetation structural regions. However, social licence, logistic and legislative constraints are the key drivers of the availability of methods for these areas. Implications Feral cat management programs should consider how program strategy can be prioritised on the basis of technique availability, region of use and expected impact.

Mortality rates of desert vegetation during high‐intensity drought at Uluru‐Kata Tjuta National Park, Central Australia

AbstractPrecipitation variability and heatwaves are expected to intensify over much of inland Australia under most projected climate change scenarios. This will undoubtedly have impacts on the biota of Australian dryland systems. However, accurate modelling of these impacts is presently impeded by a lack of empirical research on drought/heatwave effects on native arid flora and fauna. During the 2018–2021 Australian drought, many parts of the continent's inland experienced their hottest, driest period on record. Here, we present the results of a field survey in 2021 involving indigenous rangers, scientists and national parks staff who assessed plant dieback during this drought at Uluru‐Kata Tjuta National Park (UKTNP), central Australia. Spatially randomized quadrat sampling of eight common and culturally important plants indicated the following plant death rates across UKTNP (in order of drought susceptibility): desert myrtle (Aluta maisonneuvei subsp. maisonneuvei) (91%), yellow flame grevillea (Grevillea eriostachya) (79%), Maitland's wattle (Acacia maitlandii) (67%), waxy wattle (A. melleodora) (65%), soft spinifex grass (Triodia pungens) (53%), mulga (A. aneura) (42%), desert oak (Allocasuarina decaisneana) (22%) and quandong (Santalum acuminatum) (0%). The sampling also detected that seedling recruitment was absent or minimal for all plants except soft spinifex, while a generalized linear mixed model (GLMM) indicated two‐way interactions among species, plant size and stand density as important predictors of drought survival of adult plants. A substantial loss of biodiversity has occurred at UKTNP during the recent drought, with likely drivers of widespread plant mortality being extreme multi‐year rainfall deficit (2019 recorded the lowest‐ever annual rainfall at UKTNP [27 mm]) and record high summer temperatures (December 2019 recorded the highest‐ever temperature [47.1°C]). Our findings indicate that widespread plant death and extensive vegetation restructuring will occur across arid Australia if the severity and frequency of droughts increase under climate change.

Urban billabong restoration benefits from Traditional Owner involvement and regular flooding

Context Floodplain wetlands (e.g. billabongs) in urban environments have significant ecological and cultural value, yet are often highly degraded. Impacts such as reduced flooding and weed invasion continue to threaten these critical ecosystems. Both ecological and Indigenous people’s knowledge are important for urban billabong restoration. Aims Our project aimed to (1) assess the response of billabong vegetation to flooding, and (2) increase the role of local Traditional Owners in billabong management. Methods Over 3 years, a team of wetland ecologists and local Wurundjeri Woi Wurrung Narrap (‘Country’) Rangers surveyed responses of understorey vegetation and the condition and flowering of remnant river red gums (Eucalyptus camaldulensis) to flooding across seven degraded billabongs adjacent to the Birrarung (Yarra River) in Melbourne, Australia. Knowledge sharing during ‘On Country’ days guided restoration targets and management direction. Key results Regular (at least 2 in 3 years) and longer-duration (up to 8 months) flooding promoted native wetland plants, supressed weeds, and improved the condition and reproductive output of river red gums. Monitoring by Indigenous Rangers facilitated the cultural practice of caring for Country. Conclusions Regular flooding and Traditional Owner involvement promotes billabong health. Implications Collaborative research and knowledge sharing with Traditional Owners advances wetland restoration practice and improves care of Country.

Expanding the biocultural benefits of species distribution modelling with Indigenous collaborators: Case study from northern Australia

Urgent calls for biocultural conservation highlight the need to engage with Indigenous peoples, whose lands cover some of the most biodiverse regions on Earth. In these places, Indigenous knowledge can be strong, especially for culturally significant species; however, this knowledge tends to be overlooked and deemed incompatible with dominant Western systems of conservation decision-making. The practical mechanics of how Indigenous and Western knowledge systems can be respectfully synergized to inform species conservation decision-making on a regional scale are not well documented. In collaboration with Yolŋu Indigenous rangers from northern Australia, we used a ‘multiple evidence based’ approach to synergize knowledge from senior Yolŋu custodians with Western scientific species distribution modelling (SDM) to explore distribution shifts and biocultural knowledge of two culturally significant, near threatened (critical weight range) mammals: wan'kurra, (Northern Brown Bandicoot, Isoodon macrourus) and marrŋu/rupu (Common Brushtail Possum, Trichosurus vulpecula). Historical Yolŋu species sightings and seasonal observations and the SDM revealed spatial contractions of both species to the northern and mesic regions of the Laynhapuy Indigenous Protected Area over the last 50 years. Knowledge custodians were concerned about the loss of these species and associated cultural knowledge in younger generations. Such cross-cultural knowledge gathering can guide biocultural conservation decision-making and facilitate intergenerational knowledge transmission of threatened cultural knowledge. This approach to collaborative cross-cultural fauna research can be applied globally, and we argue is imperative in contexts where: species and cultures are under threat, and where Indigenous knowledge and peoples can provide insight to inform inclusive biocultural conservation strategies.

Indigenous knowledge in conservation science and the process of a two‐way research collaboration

AbstractEnvironmental research often occurs in short bursts with the duration of fieldwork often governed by the time constraints of a funding body. Collaborations between academic researchers and Indigenous People have occurred for many years and the exchange of information can create value and knowledge for both participants in the collaboration. Indigenous People play a vital role as knowledge keepers in environmental science and can, in some instances, provide a more secure repository of local knowledge and conservation practice than digital archives. In this essay, Indigenous Rangers on Larrakia country in Darwin, Australia, and a non‐Indigenous academic researcher describe how value‐creation was increased for both parties involved in a collaborative project on the migratory shorebird far eastern curlew (Numenius madagascariensis). We share our experiences of expectations, the development of methods, the codeveloped goals and complementary ways of thinking to manage threatened species at a local scale, the scale at which the local Larrakia People operate. Through our collaboration, we show that both parties within the collaboration can benefit and create value for a species of conservation concern that has not typically been considered culturally important.

Cross‐cultural collaboration leads to greater understanding of the rare Spectacled Hare‐wallaby in the west Kimberley, Western Australia

SummaryCross‐cultural collaboration between Yawuru Country Managers (Rangers) and WWF‐Australia ecologists led to new detections of the Spectacled Hare‐wallaby (SHW), (Lagorchestes conspicillatus) in the west Kimberley region of Western Australia where it was presumed to be locally extirpated. This collaboration relied on the expertise of the Yawuru Country Managers to select specific locations for targeted field surveys and resulted in the confirmation of SHW on the Yawuru IPA for the first time in a decade. Subsequent remote camera trap surveys over a larger area included collaboration with two additional neighbouring Indigenous ranger groups, Karrajarri and Nyikina Mangala. These surveys investigated the spatial and temporal relationship between SHW and other mammals which may threaten (e.g., feral Cat [Felis catus], Dingo [Canis familiaris dingo]) or compete (e.g., Agile Wallaby [Macropus agilis]; Cattle [Bos taurus]) with them. We found a negative relationship between SHW and cat activity, suggesting that cats may limit the activity or abundance of SHW. Temporal portioning was evident between SHW and both Cattle and Agile Wallaby suggesting that SHW may avoid times when these species are most active. Further, we found a negative relationship between SHW occurrence and distance to fire scar edge burnt in current or previous fire season. This edge habitat is likely important to SHW because they may require recently burnt areas to forage and dense unburnt areas to shelter. This project highlights the benefits of cross‐cultural research and monitoring partnerships with Indigenous rangers as active observers and managers of their traditional lands.

Cultural Understanding and Dialogue within the Canadian Armed Forces: Insights from Canadian Ranger Patrols

In November 2015, Prime Minister Trudeau stressed in his Minister of Defence Mandate Letter that “no relationship is more important to me and to Canada than the relationship with Indigenous Peoples. It is time to renew the nation-to-nation relationship with Indigenous Peoples so that it is based on recognition of rights, respect, collaboration and partnership.” In order to assess the relationships between Indigenous Peoples and the Canadian Armed Forces (CAF), this article is centred on the relationships between Indigenous reservists and non-Indigenous military. Based on an inductive analysis of semi-structured interviews and field observations conducted in 2016 and 2017 in Nunavik, Quebec, and Nunavut, this contribution studies the relationships between Indigenous reservists and military within Canadian Rangers patrols, and aims at demonstrating how those patrols reinforce understanding and dialogue between the different cultures. As a subcomponent of the Canadian Armed Forces Reserve, Canadian Ranger patrols from Nunavik and Nunavut are mainly composed of Indigenous Rangers under the responsibility of non-Indigenous Ranger instructors. Providing a meeting place between Indigenous and non-Indigenous individuals, the patrols enable cultural understanding and dialogue between different cultures. An analysis of the relationships within those patrols offers a particularly relevant illustration of Inuit issues and people in the Canadian Armed Forces, and more broadly in Canadian society.

Examining the Associations between Indigenous Rangers, Culture and Wellbeing in Australia, 2018-2020.

The centrality of culture to Indigenous peoples’ health and wellbeing is becoming increasingly acknowledged in government policy. In Australia, the Indigenous Ranger program is a leading example of employment that supports increased cultural participation. In 2017, we demonstrated higher life satisfaction and family wellbeing among Indigenous Rangers compared to non-Rangers in Central Australia. Using an expanded national dataset, this present study aimed to: examine if associations between Ranger status and wellbeing continued to be observed in Central Australia; assess if these associations were observed among non-Central Australian Rangers; and, quantify the effect of mediating variables (Rangers status, cultural factors) on wellbeing outcomes. We analyzed Mayi Kuwayu baseline data (n = 9691 Aboriginal and Torres Strait Islander people) and compared participants who identified as past or currently employed Rangers compared to non-Rangers across two geographic locations (Central Australia, non-Central Australia). Ranger participation was significantly associated with very high life satisfaction and family wellbeing in Central Australia (high life satisfaction PR 1.31, 95% CI 1.09–1.57, and family wellbeing (PR 1.17, 95% CI 1.01–1.36) and non-Central Australia (high life satisfaction PR 1.29, 95% CI 1.06–1.57), family wellbeing (PR 1.37, 95% CI 1.14–1.65). These findings concord with those observed in the 2017 proof-of-concept study. Additionally, we found that Ranger status partially mediated the relationships between existing cultural practices (first language as your Indigenous language and living on your country) and the two wellbeing outcomes. Current cultural practices, spending time on country and speaking your Aboriginal language, also partially mediated the associations between Ranger status and high life satisfaction, and between Ranger status and high family wellbeing. This analysis supports evidence that both Ranger employment and cultural participation are contributors to wellbeing. Ranger work is not only good for land, but it is good for people. As such, determining policies that mutually acknowledge and enhance culture, health and wellbeing will likely have additional benefits for the broader Aboriginal and Torres Strait Islander population.

Frame Analysis: An Inclusive Stakeholder Analysis Tool for Companion Animal Management in Remote Aboriginal Communities.

Simple SummaryThe management of dogs and cats in remote communities is challenging due to limited availability of veterinary services and high reproductive rates in companion animal populations. Support for animal management within communities is also weak, and consequently, programs delivered by external providers rarely achieve sustainable outcomes. An alternative approach whereby communities are engaged in analysing and understanding the issues, and designing solutions themselves, may help to achieve sustainable improvements in animal populations and health management. To test this approach, stakeholders involved with animal management in a remote Australian Aboriginal community were interviewed to gain their perspectives on animal management. By applying frame analysis to understand stakeholders’ perceptions, knowledge and power, interviewees fell into four distinct groups: Indigenous Locals, Indigenous Rangers, Non-Indigenous Locals and Animal Managers. The most important issue identified by all groups was the overpopulation of dogs, but there were differences in their framing of the problem and its causes. Frame analysis achieved the important first step of the process, identifying “What is the issue?”.Companion animal management in Australian remote Aboriginal communities (rAcs) is a complex problem, with multiple stakeholders involved with differing needs, knowledge, power and resources. We present our CoMM4Unity approach, a participatory systemic action research process designed to address such problems. In the first step, frame analysis is used to analyse stakeholders’ perspectives, knowledge types and power dynamics to determine their relative roles in animal management. Twenty individuals were interviewed from stakeholder groups involved in animal management in the remote, island rAc of Wurrumiyanga, Tiwi Islands. Frame analysis indicated that stakeholders aligned into four groups with distinct identity frames, knowledge types and power frames: Indigenous Locals, Indigenous Rangers, Non-Indigenous Locals and Animal Managers. All four groups shared overlapping perceptions about companion animals in Wurrumiyanga, and agreed that dog overpopulation was the primary issue. However, the groups differed in their strength of opinions about how dogs should be managed. Therefore, the situation is not one of diametrically opposing frames but more a misalignment of goals and values. Our application showed that frame analysis can reveal subtle variations in stakeholder groups’ identities, goals and values, and hence how they prioritise management measures.

Restoring cultural plant communities at sacred water sites

ABSTRACT Water places have been critical to central Australian Indigenous peoples for thousands of years. However, many waterhole communities have been degraded by factors including invasion by large feral herbivores and non-native plants. We document the restoration of two waterholes near Santa Teresa (Ltyentye Apurte), with a focus on culturally significant plants. We described plant communities around waterholes in 2007, before fences were erected to exclude large feral animals, and again in 2018. Plant cover and diversity were higher after fencing and the occurrence of culturally significant plants greatly increased. However, invasive buffel grass was the dominant ground cover after fencing and will require active suppression to allow culturally significant native plants to proliferate. Traditional Owners identified excellent opportunities to achieve restoration through educating young people, with a focus on sharing intergenerational knowledge and engaging local Indigenous rangers in management, enabling them to meet the traditional obligations to care for country.

Indigenous cultural burning had less impact than wildfire on the threatened Backwater grevillea (

Indigenous self-determination, land rights and caring for Country programs are enabling Indigenous peoples across the world to re-establish customary roles in biodiversity conservation and cultural fire management. In Australia, Indigenous-controlled lands form the majority of the protected area estate, harbour almost 60% of listed threatened species and maintain high levels of biodiversity. This study used cross-cultural (Indigenous and Western academic) methods to monitor the impact of Indigenous cultural burning v. wildfire on the threatened plant, Backwater grevillea (Grevillea scortechinii subsp. sarmentosa). Cultural burning resulted in lower mature grevillea mortality and less impact on reproductive output than wildfire. Both fires stimulated a mass germination but the cultural burn preserved a multi-aged population while the wildfire killed 99.6% of mature shrubs. Comparison of fuel load changes resulting from cultural burning, hazard reduction burning and wildfire indicated that fuel loads were reduced by all fire treatments, although the cultural burn was less severe than other fires. Our case study of the Backwater grevillea and its Banbai custodians provides an example where Indigenous rangers have adopted a plant into their cultural management framework. They are conserving this threatened species using culturally driven, holistic management that is locally focused and supported by cross-cultural knowledge.

A Methodology for the Assessment of Climate Change Adaptation Options for Cultural Heritage Sites

Cultural sites are particularly important to Indigenous peoples, their identity, cosmology and sociopolitical traditions. The benefits of local control, and a lack of professional resources, necessitate the development of planning tools that support independent Indigenous cultural site adaptation. We devised and tested a methodology for non-heritage professionals to analyse options that address site loss, build site resilience and build local adaptive capacity. Indigenous rangers from Kakadu National Park and the Djelk Indigenous Protected Area, Arnhem Land, Australia, were engaged as fellow researchers via a participatory action research methodology. Rangers rejected coastal defences and relocating sites, instead prioritising routine use of a risk field survey, documentation of vulnerable sites using new digital technologies and widely communicating the climate change vulnerability of sites via a video documentary. Results support the view that rigorous approaches to cultural site adaptation can be employed independently by local Indigenous stakeholders.

Indigenous guardians as an emerging approach to indigenous environmental governance.

Over the past 3 decades, indigenous guardian programs (also known as indigenous rangers or watchmen) have emerged as an institution for indigenous governments to engage in collaborative environmental governance. Using a systematic review of peer‐reviewed literature for research conducted in Australia, Canada, Aotearoa‐New Zealand, and the United States, we sought to characterize the emergence of indigenous guardians in the literature and explore whether guardian approaches are representative of Indigenous approaches to environmental governance. Using a multistep relevance‐screening method, we reviewed 83 articles published since 1995, that report on, critique, or comment on Indigenous guardians. Our findings indicated that most articles on the topic were published in the last decade (88%), focused on Australia (65%), and were in a social science discipline (53%). The lead author of the majority of articles was an academic, although only half of the articles included an indigenous scholar or member of an indigenous group or organization as a coauthor. Finally, 11 articles were on research of guardian programs that were locally led and only 5 exemplified indigenous governance, based on 2 well‐known community‐based monitoring typologies. Our findings indicate that more research is required to understand the implications of current guardian programs for indigenous self‐determination, particularly when such programs are embedded in a broader western environmental governance structure.

Indigenous Knowledge and Seasonal Calendar Inform Adaptive Savanna Burning in Northern Australia

Indigenous fire management is experiencing a resurgence worldwide. Northern Australia is the world leader in Indigenous savanna burning, delivering social, cultural, environmental and economic benefits. In 2016, a greenhouse gas abatement fire program commenced in the savannas of south-eastern Arnhem Land in the Northern Territory, managed by the Indigenous Yugul Mangi rangers. We undertook participatory action research and semi-structured interviews with rangers and Elders during 2016 and 2019 to investigate Indigenous knowledge and obtain local feedback about fire management. Results indicated that Indigenous rangers effectively use cross-cultural science (including local and Traditional Ecological Knowledge alongside western science) to manage fire. Fire management is a key driver in the production of bush tucker (wild food) resources and impacts other cultural and ecological values. A need for increased education and awareness about Indigenous burning was consistently emphasized. To address this, the project participants developed the Yugul Mangi Faiya En Sisen Kelenda (Yugul Mangi Fire and Seasons Calendar) that drew on Indigenous knowledge of seasonal biocultural indicators to guide the rangers’ fire management planning. The calendar has potential for application in fire management planning, intergenerational transfer of Indigenous knowledge and locally driven adaptive fire management.

A call for collaboration: linking local and non-local rangeland communities to build resilience

The people who live in Australia’s rangelands are vital for maintaining natural systems, agricultural production, infrastructure for tourism and many services and products which benefit the nation. However, the number of people living within many rangeland regions is declining, services are being withdrawn and resilience undermined. Social capital is an important concept within the resilience literature. Bonding social capital is based strong ties within relatively homogenous local groups, bridging social capital is based on ties between more diverse local groups and linking social capital is based on ties between local and external groups. Within the rangelands, there are often strong bonding and bridging social capitals based on internal social and formal connections, but gaps in linking social capital due to weak or imbalanced connections with external groups and organisations. There is evidence that all three social capitals are needed for regional resilience, and the gap in linking is thus a key issue. People who live outside the rangelands can help rebuild this resilience by linking their skills, knowledge and expertise with local groups and communities. Many city-based scientists, policy makers, influencers and other professionals work in and have empathy for the rangelands. By connecting meaningfully with local groups such as Landcare, service clubs, philanthropic groups or Indigenous Rangers, they would find many benefits to their own endeavours through improved policies, knowledge and service delivery. Central-western Queensland is provided as an example where many such mutual benefits and networks already exist, offering pathways for linking local residents with external experts. Current platforms offer opportunities for a greater range of external academic institutions and organisations to engage with locals, with everyone standing to gain.

Cross-Cultural Monitoring of a Cultural Keystone Species Informs Revival of Indigenous Burning of Country in South-Eastern Australia

Globally, Indigenous cultural burning has been practiced for millennia, although colonization limited Indigenous people’s ability to access and manage their ancestral lands. Recently, recognition of Indigenous fire management has been increasing, leading to the re-emergence of cultural burning in Australia, the Americas, parts of Asia and Africa. We describe how the Banbai people of south-eastern Australia have reintroduced cultural burning at Wattleridge Indigenous Protected Area. Our team of Banbai Rangers and non-Indigenous scientists conducted cross-cultural research to investigate the impact of burning on a cultural keystone species, the Short-beaked echidna (Tachyglossus aculeatus). Our comparison of the effects of a low-intensity, patchy, cultural fire in the Wattleridge Indigenous Protected Area to a nearby higher intensity fire in Warra National Park through a Before-After-Control-Impact assessment indicated that the higher intensity fire reduced echidna foraging activity, possibly to avoid predation. Most importantly, we describe a cross-cultural research model whereby Indigenous rangers and non-Indigenous scientists work together to inform adaptive natural and cultural resource management. Such trans-disciplinary and collaborative research strengthens informed conservation decision-making and the social-ecological resilience of communities.
