Contraction–Expansion Dynamics Shape Refugia and Recolonisation Processes in the Gondwana Rainforests of Australia World Heritage Area
Climate stability and historical gene flow have shaped distinct refugial and recolonised areas within the Gondwana Rainforests of Australia World Heritage Area (GRWHA), with significant implications for future conservation. The study identified persistent refugia—regions of high climate stability, species richness, and genetic differentiation—and recolonised zones marked by lower stability but higher genetic diversity. Notably, the Clarence River Corridor acts as both a biogeographic barrier and a zone of admixture, homogenizing genetic signals. While rainforest suitability expanded post-Last Glacial Maximum (LGM), future projections indicate substantial contraction, particularly in southern regions, with high-altitude refugia emerging. This multi-species approach integrates climate modeling, landscape genomics, and intraspecific diversity metrics to inform regionally tailored restoration strategies, prioritizing provenancing guidance and assisted migration under climate change.
Environmental Controls of Rainforest Tree Communities: Climate Change Implications for the Gondwana Rainforests
A 15-year study of the Gondwana Rainforests of Australia reveals significant floristic changes driven by elevation-dependent environmental controls. High-elevation tree communities (≥ 900 m) show persistent in situ recruitment patterns, closely mirroring canopy composition, and are primarily influenced by precipitation and cloud water inputs, which mitigate moisture stress. In contrast, mid-to-low elevations (≤ 700 m) exhibit distinct understorey recruit compositions differing from the established canopy, linked to higher temperatures, evaporation, and lower humidity. These changes, particularly pronounced at low elevations (300 m), are exacerbated by drought and bushfires, suggesting a trajectory toward future community turnover. Climate projections indicate increasing moisture stress and fire risk, potentially threatening the Outstanding Universal Value of this UNESCO World Heritage Area. The study used multivariate analyses to examine shifts in tree community composition and their environmental drivers, providing critical insights for management strategies.
Long-term demographic responses to historical logging and ongoing climate change in an upland subtropical rainforest
Historical logging and ongoing climate change continue to significantly impact the recovery of upland subtropical rainforests in southeast Queensland, part of Australia's Gondwana Rainforests World Heritage Site. Despite over 50 years since logging cessation, these forests show persistent structural and compositional differences compared to intact plots, with logged areas exhibiting higher recruitment of pioneer species but greater sensitivity to warming temperatures and extreme weather events. The study, utilizing a rare long-term dataset spanning 1962–2015, found that while logged plots demonstrate faster diameter growth initially, this slows as basal area increases. Intact plots, conversely, show growth concentrated in larger, cloud-water-intercepting trees. These findings highlight the enduring legacy of logging and the need for adaptive management strategies to mitigate climate change impacts on these critical biodiversity refugia.

Paleobotany reframes the fiery debate on Australia's rainforest edges
Fossil evidence from Argentina and eastern Australia reveals that biodiverse rainforests with abundant Eucalyptus existed over 50 million years ago, shaped by nonfire disturbances like landslides and volcanic flows. The dominance of fire-adapted eucalypts is linked to more recent geological and climatic changes, including C4 grassland expansion and human activity. This challenges the narrative that tall eucalypt forests (TEFs) are threatened by 'invasive' neighboring rainforests, suggesting instead that both ecosystems are part of a single humid forest system with ancient, evolving interactions. The study urges a reevaluation of management practices to protect the outstanding World Heritage values and carbon storage of these areas, emphasizing the need for restoration and research focused on rainforest margins.
Investigating the role of the World Heritage brand in attracting visitors to protected areas in Queensland, Australia
Approximately one in four visitors to UNESCO World Heritage Sites in Queensland, Australia, indicated that the World Heritage brand influenced their decision to visit. This study is the first in-depth exploration of visitor awareness and preference for the World Heritage brand, revealing that while brand recognition varies significantly across sites—with only one-third of visitors recalling it spontaneously—it remains a powerful motivator for tourism. The research developed a practical framework for understanding protected area brands' roles among stakeholders and established baseline sociodemographic data across Queensland’s World Heritage Sites. Methodologically, the study employed focus groups, visitor surveys (1,827 valid responses), expert interviews, and on-site observations, analyzing data through descriptive statistics and chi-square tests to assess brand influence. Findings have already informed national and international policy on World Heritage branding.
What type of rainforest burnt in the South East Queensland's 2019/20 bushfires and how might this impact biodiversity
During Australia's 2019/20 bushfires, 12% of South East Queensland's (SEQ) rainforest estate, including parts of the UNESCO World Heritage Gondwana Rainforests, was affected by fires. Surprisingly, the wettest rainforest types and putative past refugia experienced higher burn rates than expected, challenging traditional assumptions about fire resilience in such ecosystems. The study used NIAFED data combined with regional ecosystem mapping to estimate burn areas and severity, revealing that while most fires were low-severity, patches of high severity occurred. Biodiversity impacts were assessed using previous estimates for each rainforest type, highlighting the potential threat to endangered rainforest species like semi-evergreen vine thickets on igneous rocks, where 50% of remnants may have burned. The findings suggest that under drought conditions, any rainforest is vulnerable, implying a contraction of rainforest areas if climate change exacerbates wildfires and droughts.
A new species of Philoria (Anura: Limnodynastidae) from the uplands of the Gondwana Rainforests World Heritage Area of eastern Australia
Researchers have identified a new species of mountain frog, Philoria knowlesi, within the Gondwana Rainforests World Heritage Area of eastern Australia. This discovery was made through comprehensive genetic sampling and analysis, including SNP data from the nuclear genome, which revealed distinct genetic lineages in the central and western McPherson Ranges. The study also clarified the distributions of two other species, P. loveridgei and P. kundagungan, while highlighting significant threats to these amphibians, including climate change and chytridiomycosis. All three taxa—Philoria knowlesi, P. loveridgei, and P. kundagungan (including its northern subpopulation)—are classified as Endangered (EN), with the southern subpopulation of P. kundagungan critically endangered (CR). The findings underscore the urgent need for conservation efforts to protect these highly threatened species.
Beyond bushfire severity: mapping the ecological impact of bushfires on the Gondwana Rainforests of Australia World Heritage Area
Bushfire severity mapping in Queensland's Gondwana Rainforests World Heritage Area properties following the 2019/20 wildfires was found to under-predict ecological impact, particularly in closed-canopy rainforests. This oversight biased against prioritizing rainforest-dependent threatened fauna for assessment and recovery resource allocation. The study introduces an approach that incorporates fire tolerance of vegetation communities to extend bushfire severity mapping, predicting potential ecological impact on ecosystems and priority species. By prioritizing threatened species based on ecological impact rather than fire severity alone, post-fire surveys and monitoring can be more effectively targeted, directing resources and recovery actions towards areas of greatest concern.
Extensive range contraction predicted under climate warming for two endangered mountaintop frogs from the rainforests of subtropical Australia
Two endangered mountaintop frogs, Philoria kundagungan and Philoria richmondensis, endemic to the Gondwana Rainforests of Australia World Heritage Area (GRAWHA), face severe range contraction due to climate warming. Under projected low and high warming scenarios by 2055, their habitats are expected to shrink by 64% to 91% for P. kundagungan and 50% to 85% for P. richmondensis, respectively. The study used the maximum entropy approach to model current and future distributions, validated against field data, revealing alarming declines that necessitate urgent conservation action. Proposed strategies include establishing ex-situ insurance populations and conservation translocations to ensure long-term survival amid ongoing threats such as wildfires.
Propositional A/r/tography: An Analytical Protocol

Conserving Refugia: What Are We Protecting and Why?
Refugia serve as vital conservation tools by buffering environmental conditions and safeguarding species and communities. This study introduces three novel definitions for refugia—persistent, future, and temporary—that integrate ecological and evolutionary dynamics into a decision-making framework applicable across varying temporal and spatial settings. These definitions are supported by criteria for identification, core value, and management strategies to guide both short- and long-term conservation efforts. Using the World Heritage Gondwana Rainforests (WHGR) of eastern Australia as a case study, the research illustrates how recognizing buffer zones, corridor connections, and emergency species translocations can protect critical assets following extreme events like the 2019–2020 fires. The findings emphasize the importance of safeguarding ecological and evolutionary processes across scales to enhance biodiversity conservation outcomes.
Disparate origins for endemic bird taxa from the ‘Gondwana Rainforests’ of Central Eastern Australia
A phylogenetic analysis of eight bird taxa endemic to Central Eastern Australia's Gondwana Rainforests reveals disparate origins, with five showing Plio-Pleistocene divergences from northern relatives, indicating recent lowland rainforest expansion and contraction. In contrast, two upland species, the rufous scrub-bird and logrunner, diverged during the Miocene, suggesting longer persistence and temperate origins. Additionally, reciprocal monophyly was not recovered in mitogenomes of Albert’s lyrebird and superb lyrebird. These findings support the rainforests' biota comprising isolates of varying ages and origins.

Evolutionary Biogeography of the Australian Flora in the Cenozoic Era
The Gondwana Rainforests of Australia have been shaped by a complex interplay of contraction and diversification over the last 65 million years. A once-widespread mesic flora, comprising both rainforest and sclerophyll elements, has given way to an expansion and diversification of dry-adapted, fire-tolerant species, particularly sclerophyllous groups. While many species trace their lineage back to Australia's isolation following Gondwana's breakup, the continent's flora also reflects significant migration patterns, including trans-oceanic dispersal among southern hemisphere landmasses and exchanges with Asia. Despite clear historical biogeographic patterns—such as the separation of mesic zones in southwestern and southeastern Australia—many processes remain poorly understood.
Molecular Biogeography of Australian and New Zealand Reptiles and Amphibians
Reptiles and amphibians, though ubiquitous in Australia and New Zealand, exhibit markedly distinct taxonomic compositions due to the continents' divergent geological histories. Australia's ancient, arid landscape contrasts with New Zealand's young, geologically active terrain, shaped by Gondwana's breakup and recent climatic fluctuations. These factors have driven adaptive radiations, resulting in unique herpetofaunal diversity across both regions. The study employs molecular biogeography to elucidate these evolutionary patterns, highlighting the influence of tectonic processes and environmental changes on reptile and amphibian distributions.
Protected area management under climate change: A framework for decision making
Protected areas worldwide face increasing threats from climate change, necessitating adaptive management strategies that go beyond traditional static boundary approaches. This study developed a climate change adaptation framework to guide on-park decision-making for the Gondwana Rainforests of Australia World Heritage Site, focusing on four Queensland national parks: Springbrook, Lamington, Mount Barney, and Main Range. The research identified socio-ecological attributes as critical for effective park planning and management, incorporating Bayesian belief networks to assess climate change impacts on key values such as stream-dwelling frogs, cool temperate forest, and recreational walking access. A workshop with Queensland Parks and Wildlife planners evaluated the feasibility of management strategies, highlighting the need for flexibility, resource efficiency, and sometimes challenging community or agency principles to sustain protected areas under changing climates.
Using automated acoustic monitoring to detect elevational migration in the avian community of the Gondwana Rainforests of Australia
Automated acoustic monitoring revealed seasonal elevational migration among resident bird species in Australia's Gondwana Rainforests, marking the first comprehensive avian biodiversity survey in the region. This study demonstrated that affordable bioacoustic recorders could efficiently collect large-scale, long-term data on species distributions, migratory patterns, and breeding behaviors—previously challenging to obtain. By analyzing 14 months of continuous recordings along two elevational gradients in northern New South Wales, researchers identified key insights into avian ecology, including the arrival and departure times of migratory species and the reproductive activity of cryptic species. These findings provide critical baseline data for understanding climate change impacts on rainforest avifauna and guiding conservation strategies.
The distribution of epiphytes over environmental and habitat gradients in tropical and subtropical Australia
Epiphytes in Australia's Gondwana Rainforests exhibit predictable distributions influenced primarily by moisture and light gradients, with vascular epiphytes showing species richness peaks at mid-elevations (500-700 m) and distinct partitioning over continuous light and vapour pressure deficit (VPD) gradients. Unlike mosses, which display uniform distribution across height zones, vascular epiphytes, such as orchids and ferns, occupy specific microclimatic niches, suggesting fine-scale habitat patchiness within host trees. The study also found that drought-mitigating traits in vascular epiphytes correlate with xeric conditions, while broader zonation systems like the Johansson zones may overlook intra-zone microhabitat variations. These findings highlight the critical role of microclimate in epiphyte survival and underscore the need for further research to mitigate biodiversity loss under climate change.
Conservation of imperiled crayfish, Euastacus clarkae Morgan, 1997 (Decapoda: Parastacidae), a highland crayfish from the Gondwana Rainforests of Australia’s World Heritage Area
A recent comprehensive survey of the Gondwana Rainforests of Australia’s World Heritage Area has significantly advanced the conservation understanding of Clark’s crayfish (Euastacus clarkae), a critically endangered highland species. The study, conducted by the Australian Crayfish Project, mapped its distribution across the entire Hastings River catchment (3846 km²), revealing that the species is confined to headwater streams at elevations between 670–1150 meters, with an Extent of Occurrence of just 200 km². Nearly all populations were found within Werrikimbe National Park, where they are locally abundant. Based on these findings, researchers recommend downlisting the species from Critically Endangered to Endangered in conservation assessments. The study also provides a key for identifying Euastacus crayfish species in the region and offers critical data to inform future management strategies.
If a frog calls in the forest: Bioacoustic monitoring reveals the breeding phenology of the endangered R ichmond R ange mountain frog ( P hiloria richmondensis)
Bioacoustic monitoring of the endangered Richmond Range mountain frog (Philoria richmondensis) in Australia's Gondwana Rainforests reveals that peak calling activity occurs during austral spring mornings and evenings, with ambient temperature (15–16°C) significantly influencing call frequency. A negative relationship between precipitation and calling activity was also observed. These findings provide a benchmark for detecting phenological shifts due to climate change and optimize future survey efforts by targeting periods of high acoustic detectability.
Species turnover of corticolous bryophyte assemblages over 15 years in an Australian subtropical cloud forest
A 15-year study of corticolous bryophyte assemblages in the Gondwana Rainforests of Australia World Heritage Area reveals significant species turnover, particularly among liverworts (43–62%), despite limited changes in overall species richness. Liverwort communities exhibit strong spatial patterns linked to orographic moisture exposure from south-easterly winds, suggesting microclimatic factors drive their assemblages more than mosses. The study posits that temporal fluctuations in moisture inputs from orographic clouds—undetectable via precipitation records—are likely responsible for the observed directional changes in liverwort communities. This research highlights the vulnerability of subtropical cloud forests to climatic shifts and underscores the need for long-term ecological monitoring.
Some new and noteworthy bryophytes from Antarctic Beech (Nothofagus moorei) forests of north-eastern New South Wales
Research in the Gondwana Rainforests of Australia has uncovered several new and noteworthy bryophytes, including rare mosses and liverworts. Among the discoveries are the epiphytic moss Rosulabryum epiphyticum, the moss Leptodontium viticulosoides, and endemic species of Macromitrium. Additionally, two species, Fissidens thorsbornei (synonym: Nanobryum thorsbornei) and the liverwort Lejeunea gracilipes, were recorded for the first time in New South Wales. These findings highlight the biodiversity of the region, particularly within Antarctic Beech (Nothofagus moorei) forests, despite bryophytes being absent from the site's statement of outstanding universal values. The study used bryophytes as fine-scale indicators to assess rainforest condition, contributing valuable insights into the ecological significance of this globally recognized heritage area.
The evolutionary history of the Australian flora and its relevance to biodiversity conservation
Australia's unique flora, once part of the ancient supercontinent Gondwana, has undergone significant evolutionary changes due to shifting environmental conditions from wet to dry climates. While fossil records indicate a prevalence of rainforest communities during the Tertiary period, the continent's flora adapted to cooler, drier, and more seasonal environments. Quaternary glacial cycles further altered plant communities, creating transitional ecosystems distinct from today's landscapes. However, human activity has introduced new pressures, including habitat degradation, invasive species, and intensive land use, posing severe threats to biodiversity. The study emphasizes the need for proactive conservation strategies that integrate an understanding of species vulnerability to past, present, and future environmental changes.
Trophic cascades in bell miner‐associated dieback forests: Quantifying relationships between leaf quality, psyllids and P syllaephagus parasitoids
A significant negative correlation was found between leaf toughness and foliar nitrogen content, indicating that younger leaves with higher nitrogen levels support greater psyllid abundances. This relationship is further influenced by the presence of bell miners (Manorina melanophrys), which protect psyllids from predation, thereby promoting lerp-forming psyllids—some of which reduce leaf lifespan. The study, conducted in the Gondwana Rainforests of Australia World Heritage Area, identified 14 Psyllaephagus species, including primary parasitoids and hyperparasitoids, with their abundances positively linked to lerp availability but not directly to psyllid parasitism rates. Epicormic foliage, produced post-defoliation, may enhance Glycaspis psyllid populations, creating 'lerp hotspots' that attract bell miners. These findings suggest complex trophic interactions and feedback mechanisms in bell miner-associated dieback (BMAD) forests, warranting further longitudinal study.
