Identification of spatial gradients in ecosystem vulnerability to global climate change and local stressors is an important step in the formulation and implementation of appropriate countermeasures. Here we build on recent work to map ecoregional exposure to future climate, using an envelope-based gauge of future climate stability—defined as a meas...

The acquisition or designation of new protected areas is usually based on criteria for representation of different ecosystems or land-cover classes, and it is unclear how well-threatened species are conserved within protected-area networks. Here, we assessed how Australia's terrestrial protected-area system (89 million ha, 11.6% of the continent) o...

The Galapagos Archipelago is renowned for its high endemism but little effort has been made to quantify the human disturbance that compromises the islands' ecological integrity. We provide a quantitative assessment of anthropogenic degradation, which we define as areas either transformed by direct human activity or heavily invaded by four of the mo...

Extensive forest restoration is a key strategy to meet nature-based sustainable development goals and provide multiple social and environmental benefits¹. Yet achieving forest restoration at scale requires cost-effective methods². Tree planting in degraded landscapes is a popular but costly forest restoration method that often results in less biodi...

Protected area downgrading, downsizing, and degazettement (PADDD) is a common occurrence. Although PADDD is expected to weaken biodiversity protection, PADDD offsets and new unrelated protected areas (PAs) could help restore representation of biodiversity features to the reserve network affected by PADDD. Globally, we analyzed 16 territories with t...

Intact native forests under negligible large-scale human pressures (i.e. high-integrity forests) are critical for biodiversity conservation. However, high-integrity forests are declining worldwide due to deforestation and forest degradation. Recognizing the importance of high-integrity ecosystems (including forests), the Kunming-Montreal Global Bio...

The Kunming‐Montreal Global Biodiversity Framework lays out an ambitious set of goals and targets aimed at halting and reversing biodiversity loss. The extent of natural ecosystems has been selected as one of a small set of headline indicators against which countries will report progress under this framework. We evaluate the effectiveness with whic...

Many of the proposed solutions to the global biodiversity crisis rely on national governments to act. The conservation movement needs to motivate governments or face an ongoing extinction crisis. Here we explore how linking biodiversity to electoral systems may assist in motivating government action. Using Australia as a case study, we analyze the...

Despite the importance of protecting forests and woodlands to achieve global climate and biodiversity goals, logging impacts persist worldwide. Forestry advocates often downplay these impacts but rarely consider the cumulative threat deforestation and degradation has had, and continues to have, on biodiversity. Using New South Wales (Australia) as...

The Kunming–Montreal Global Biodiversity Framework (GBF) will become the most important multilateral agreement to guide biodiversity conservation actions globally over the coming decades. An ecosystem goal and various targets for maintaining integrity, restoring degraded ecosystems, and achieving representation in conservation areas feature through...

We report the first detection and prevalence of Beak and feather disease virus (BFDV) in Australia’s Red Goshawk (Erythrotriorchis radiatus). This is a new host for this pervasive pathogen amongst a growing list of non-psittacine species including birds of prey from the orders Accipitriformes (hawks, eagles, kites), Falconiformes (falcons and carac...

Received wisdom has argued that large protected areas are superior to small reserves, based on island biogeography theory, economies of scale, and the need to sustain viable populations of top predators and other large ranging or dispersive species. But this position overlooks evidence that, for many species, strategically placed smaller reserves a...

Aim Colombia has committed to ambitious forest restoration targets which include a 1 million ha Bonn Challenge commitment and 6.47–8.31 million ha (rehabilitation and restoration, respectively) under the National Restoration Plan. Determining where and how to implement programs to achieve these targets remains a significant challenge. Location Col...

Most biodiversity monitoring globally tends to concentrate on trends in species’ populations and ranges rather than on threats and their management. Here we review the estimated impact of threats and the extent to which their management is understood and implemented for all threats to all Australian threatened bird taxa. The assessment reports the...

There are many impediments to conserving threatened birds. Some can be overcome through concerted action across multiple species while others require species-specific research and intensive management. We assess the feasibility of managing 202 threats identified in the Action Plan for Australian Birds across 217 Australian threatened bird taxa agai...

Tracking the state of biodiversity over time is critical to successful conservation, but conventional monitoring schemes tend to be insufficient to adequately quantify how species' abundances and distributions are changing. One solution to this issue is to leverage data generated by citizen scientists, who collect vast quantities of data at tempora...

As anthropogenic transformation of Earth's ecology accelerates, and its impacts on the sustainability of humanity and the rest of nature become more obvious, geographers and other researchers are leveraging an abundance of spatial data to map how industrialization is transforming the biosphere. This review examines the methodologies used to create...

As part of the Kunming‐Montreal Global Biodiversity Framework (K‐M GBF), signatory nations of the Convention on Biological Diversity (CBD) aim to protect at least 30% of the planet by 2030 (Target 3). This bold ambition has been widely celebrated and its implementation seen as pivotal for the overall success of K‐M GBF. However, given that many CBD...

An evidence-based approach to the conservation management of a species requires knowledge of that species' status, distribution, ecology, and threats. Coupled with budgets for specific conservation strategies, this knowledge allows prioritisation of funding toward activities that maximise benefit for the species. However, many threatened species ar...

Although ideas about preventive actions for pandemics have been advanced during the COVID-19 crisis, there has been little consideration for how they can be operationalised through governance structures within the context of the wildlife trade for human consumption. To date, pandemic governance has mostly focused on outbreak surveillance, containme...

Budgeting for biodiversity conservation requires realistic estimates of threat abatement costs. However, data on threat management costs are often unavailable or unable to be extrapolated across relevant locations and scales. Conservation expenditure largely occurs without a priori cost estimates of management activities and is not recorded in ways...

Global efforts to deliver internationally agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services have been poorly integrated. These goals rely in part on preserving natural (e.g., native, largely unmodified) and seminatural (e.g., low intensity or sustainable human use) forests, woodlands, and grass...

Despite the importance of safeguarding forests and woodlands for achieving global climate and biodiversity agendas, logging continues across most forested countries. Forestry advocates often claim logging has minimal impacts, but rarely consider the cumulative threat deforestation and degradation has had, and continue to have, on species. Using New...

Australia’s Red Goshawk (Erythrotriorchis radiatus) is a taxonomically distinct raptor endemic to the tropics and sub-tropics of eastern and northern Australia, and the Australian mainland’s rarest bird of prey. Classified as Vulnerable when legislation was first enacted in 1992, the species’ status and distribution remain unclear, and it is possib...

Insects dominate the biosphere, yet insect populations are plummeting worldwide. Massive conservation efforts will be needed to reverse these declines. Protected areas (PAs) could act as a safeguard against extinction, but documented coverage of insect representation across the PA estate is limited. Here, we show that 76% of 89,151 insect species a...

Maintaining peace and conserving biodiversity hinge on an international system of cooperation codified in institutions, but Russia’s invasion of Ukraine brings recent progress to a crossroads. Against this backdrop, we address some implications of Russia’s invasion of Ukraine for the governance of biodiversity conservation both within and beyond Ru...

The Painted Button-quail Turnix varius is a widespread and frequently encountered ground-dwelling bird endemic to Australia. Despite being regularly recorded throughout its distribution, our understanding of this species’ vocalisations is poor. Published accounts are limited to brief descriptions without quantitative analyses in a standardised form...

Biodiversity offsets aim to counterbalance the residual impacts of development on species and ecosystems. Guidance documents explicitly recommend that biodiversity offset actions be located close to the location of impact because of higher potential for similar ecological conditions, but allowing greater spatial flexibility has been proposed. We ex...

Earth’s wilderness areas are reservoirs of genetic information and carbon storage systems, and are vital to reducing extinction risks. Retaining the conservation value of these areas is fundamental to achieving global biodiversity conservation goals; however, climate and land-use risk can undermine their ability to provide these functions. The exte...

All tropical savannahs are experiencing extensive transformation and degradation, yet conservation strategies do not adequately address threats to savannahs. Here, using a recently published ecosystem intactness metric, we assess the current condition of tropical savannahs across Earth, finding that <3 % remain highly intact. Moreover, their overal...

The draft Global Biodiversity Framework proposes to increase protected areas and OECMs to at least 30 per cent of land and ocean by 2030 (30x30). Such areas are central to conservation, but only if effectively managed and equitably governed. In practice, governments often recognise areas that do not achieve successful outcomes or respect human righ...

Mining companies increasingly commit to a net positive impact on biodiversity. However, assessing the industry's progress toward achieving this goal is limited by knowledge of current mining threats to biodiversity and the relevant opportunities available for them to improve conservation outcomes. Here, we investigate the global exposure of terrest...

Reducing deforestation underpins global biodiversity conservation efforts. However, this focus on retaining forest cover overlooks the multitude of anthropogenic pressures that can degrade forest quality and imperil biodiversity. We use remotely sensed indices of tropical rainforest structural condition and associated human pressures to quantify th...

The current ornithological literature describes the Painted Button-quail Turnix varius having a distribution in Queensland that reaches its northern limit around Cooktown. North of Cooktown, the species is thought to be replaced by the Buff-breasted Button-quail T. olivii in savanna habitats of Cape York Peninsula. Here we present observations of P...

Anthropogenic pressures are driving insect declines across the world. Although protected areas (PAs) play a prominent role in safeguarding many vertebrate species from human-induced threats, insects are not widely considered when designing PA systems or building strategies for PA management. We review the effectiveness of PAs for insect conservatio...

Among the conservation community, it is well known that Earth’s mass species extinction crisis is getting worse. Yet, an often neglected problem is the need for effectively communicating the species extinction crisis to diverse audiences in ways that catalyse immediate action. Here we generated a streamlined threatened species recovery report card...

China has emerged as the largest overseas financier of hydropower in low-income countries. Since hydropower dams pose risks to biodiversity, an examination of potential biodiversity impacts of Chinese projects is critically needed. We conducted a biodiversity risk and safeguards assessment of Chinese-funded dams being built in Belt and Road Initiat...

The 2019/20 wildfire season was devastating for Australia’s biodiversity and unprecedented in its extent and severity, yet the consequences for sites important for biodiversity and other world heritage values remain unknown. Here, we summarise the 2019/20 wildfire impacts on key sites set aside for, or identified as being important for, biodiversit...

Due to climate change, megafires are increasingly common and have sudden, extensive impacts on many species over vast areas, leaving decision makers uncertain about how best to prioritize recovery. We devised a decision‐support framework to prioritize conservation actions to improve species outcomes immediately after a megafire. Complementary locat...

In the summer of 2019–2020, southern Australia experienced the largest fires on record, detrimentally impacting the habitat of native species, many of which were already threatened by past and current anthropogenic land use. A large-scale restoration effort to improve degraded species habitat would provide fire-affected species with the chance to r...

The Buff-breasted Button-quail Turnix olivii is arguably the rarest, most threatened bird species in Australia. Despite many reports over the last four decades, the species has never been reliably photographed nor its vocalisations definitively recorded. No records in contemporary literature are supported irrefutably. Consequently, examining histor...

Ambitious conservation efforts are needed to stop the global biodiversity crisis. In this study, we estimate the minimum land area to secure important biodiversity areas, ecologically intact areas, and optimal locations for representation of species ranges and ecoregions. We discover that at least 64 million square kilometers (44% of terrestrial ar...

Many threats to biodiversity can be predicted and are well mapped but others are uncertain in their extent, impact on biodiversity, and ability for conservation efforts to address, making them more difficult to account for in spatial conservation planning efforts, and as a result, they are often ignored. Here, we use a spatial prioritisation analys...

One of the biggest stumbling blocks for global environmental agreements is how higher-income and lower-income countries share the costs of implementing them. This problem has become particularly acute as biodiversity and climate ambitions have increased across recent COPs (Conferences of Parties). Here, we estimate the likely distribution of costs...

Indicators supporting implementation of the post-2020 Global Biodiversity Framework (GBF) are likely to be used not only to monitor progress toward achieving agreed goals and targets, but also to help prioritise specific actions to address shortfalls in this achievement as efficiently as possible. To perform this dual role, adopted indicators must...

Area-based conservation measures, including protected areas (PA) and other effective area-based conservation measures (OECM), play an important role in biodiversity conservation. In the Brazilian Amazon, even though Conservation Units and Indigenous Lands have been shown to reduce deforestation, few studies have addressed Quilombola Territories, an...

The Chestnut-backed Button-quail Turnix castanotus is a small, cryptic, ground-dwelling species endemic to savanna ecosystems of northern Australia. Due to aspects of its ecology, cryptic plumage and behaviour, and the remoteness of most of its distribution, there are few published observations from the field documenting its breeding biology. The e...
