Many nations are struggling to reduce deforestation, despite having extensive environmental protection laws in place and commitments to international agreements that address the biodiversity and climate crises. We developed a novel framework to quantify the extent to which contemporary deforestation is being captured under national and subnational...
Context
Promoting heterogeneous agricultural landscapes could help to reduce the negative impacts of habitat conversion on biota. However, the benefits of landscape heterogeneity can vary among spatial scales and taxa.
Objectives
To design biodiversity-friendly landscapes, we use nationwide bird survey data and land use maps to examine the effects...
Most protected area (PA) planning aims to improve biota representation within the PA system, but this does not necessarily achieve the best outcomes for biota retention across regions when we also consider habitat loss in areas outside the PA system. Here, we assess the implications that different PA expansion strategies can have on the retention o...
Biodiversity credits are an emerging vehicle for pro-environmental financing. Here we define and delimit biodiversity credits and explore the pathways through which credits can be issued. We scrutinize early evidence from pilots and suggest lessons from other market-based incentives for conservation and climate mitigation, including biodiversity of...
Biodiversity credits are an emerging vehicle for pro-environmental financing. Here we define and delimit biodiversity credits, explore their impact pathways, discuss potential future supply and demand, bundling/stacking options, and needed social safeguards. We scrutinize early evidence from 34 pilots and suggest lessons from other market-based inc...
Biodiversity offsets are commonly used to compensate for environmental impacts, but their effectiveness is often questioned. Estimations of expected losses and gains often rely on what we called condition metrics, which measure a site’s quality or condition using certain ecological attributes. Condition metrics are central to most offset policies,...
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...
Biodiversity offsetting is a globally influential policy mechanism for reconciling trade-offs between development and biodiversity loss. However, there is little robust evidence of its effectiveness. We evaluated the outcomes of a jurisdictional offsetting policy (Victoria, Australia). Offsets under Victoria's Native Vegetation Framework (2002-2013...
Infrastructure development is a major driver of biodiversity loss globally. With upward of US$2.5 trillion in annual investments in infrastructure, the financial sector indirectly drives this biodiversity loss. At the same time, biodiversity safeguards (project‐level biodiversity impact mitigation requirements) of infrastructure financiers can help...
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...
Biodiversity offsetting is a globally-influential policy mechanism for reconciling trade-offs between development and biodiversity loss. However, there is little robust evidence of its effectiveness. We evaluated the outcomes of a jurisdictional offsetting policy (Victoria, Australia). Offsets under Victoria’s Native Vegetation Framework (2002-2013...
Multi-species indicators (MSIs) have been useful tools for reflecting the state of taxa and ecosystems at global, regional, and national levels. However, most indicators are from Europe and North America, and there are few from the world’s major tropical and subtropical biodiversity hotspots, often in large part because of insufficient data availab...
Although several countries along the East Asian-Australasian Flyway have recently begun reporting population trends and identifying threats to migratory waterbirds, there remains rather sparse geographical coverage of systematic waterbird monitoring, impeding our understanding of the flyway-wide status of waterbird populations. To fill this gap, we...
Agriculture is the largest single source of environmental degradation, responsible for over 30% of global greenhouse gas (GHG) emissions, 70% of freshwater use and 80% of land conversion: it is the single largest driver of biodiversity loss (Foley JA, Science 309:570–574, 2005, Nature 478:337–342, 2011; IPBES. Global assessment report on biodiversi...
Addressing threats to biodiversity from pest species is a global challenge. One such challenge is to mitigate the impact of an overabundant Australian song-bird, the noisy miner Manorina melanocephala, on woodland birds. The overabundance of noisy miners is listed as a key threatening process under federal biodiversity legislation, but current unde...
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...
When designing biodiversity offset transactions, selecting the appropriate currency for measuring losses and gains to biodiversity is crucial. Poorly designed currencies reduce the likelihood that the proposed offset will sufficiently compensate for the development impact on the affected biota. We present a framework for identifying appropriate off...
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...
As fragmented landscapes become increasingly common around the world, managing the spatial arrangement of landscape elements (i.e., landscape configuration) may help to promote the conservation of biodiversity. However, the relative effects of landscape configuration on different dimensions of biodiversity across species assemblages are largely unk...
Most protected area (PA) planning aims to improve biota representation within the PA system, but this does not necessarily achieve the best outcomes for biota retention across regions when we also consider areas outside the PA system. Here we assess the implications that different PA expansion strategies can have on the retention of species habitat...
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...
Monitoring is critical to gauge the effect of environmental management interventions as well as to measure the effects of human disturbances such as climate change. Recognition of the critical need for monitoring means that, at irregular intervals, recommendations are made for new government-instigated programs or to revamp existing ones. Using ins...
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...
In the face of the ongoing biodiversity crisis, questions are arising regarding the success, or lack thereof, of biodiversity offset schemes, where biodiversity losses from human development are compensated by producing equitable gains elsewhere. The overarching goal of offsetting is to deliver no net loss (NNL) of biodiversity. Assessing whether o...
The 1972 Stockholm Conference put environmental protection on the global agenda for the first time. But since then, biodiversity losses and increasing threats have outpaced the conservation response. A step change is needed to reverse this trend and will require scaled-up action across society, including from governments, businesses, and financial...
Achieving global sustainability objectives such as the UN Sustainable Development Goals or Aichi Targets, including remaining within planetary boundaries, necessitates proactively avoiding a proportion of the environmental impacts otherwise expected to result from economic development. Quantifying these “avoided” impacts is important for monitoring...
Ecologists are increasingly using bioacoustics in wildlife monitoring programs. Remote autonomous sound recorders provide new options for collecting data for species and in contexts that were previously difficult. However, post-processing of sound files to extract relevant data remains a significant challenge. Detection algorithms, or call recogniz...
Habitat loss is driving the extirpation of fauna across Earth. Many species are now absent from vast areas where they once occurred in inhabited continents, yet we do not have a good understanding of the extent to which different species have been extirpated, nor the degree to which range contractions and habitat loss has contributed to this local...
Increasingly, government and corporate policies on ecological compensation (e.g., offsetting) are requiring “net gain” outcomes for biodiversity. This presents an opportunity to align development with the United Nations Convention on Biological Diversity Post‐2020 Global Biodiversity Framework's (GBF) proposed ambition for overall biodiversity reco...
This project developed an approach for eliciting the knowledge of threatened species experts in a structured way, so as to guide estimates of the benefits of alternative offset approaches. Although it doesn’t replace field-based studies, it can guide decision-makers in basing offset decisions on the best available information at the time, and help...
Around the world, woodlands have been cleared for agricultural production and their bird communities are in decline. To reverse these declines and foster bird community resilience, government agencies, non-government organizations, and private landholders have implemented restoration actions, commonly including grazing exclusion and replanting. The...
Northern Australia is the focus of intense development and investment interest. At the
Commonwealth level alone, promotion of the northern Australia development agenda is facilitated by a dedicated Ministerial portfolio and departmental office, a road map for investment opportunities and policy reform (‘White Paper on Developing Northern Australia’...
Abstract Controlling problem species for conservation can be fraught, particularly when native species are subject to lethal control. The noisy miner (Manorina melanocephala), has been the target of numerous lethal control efforts. Outcomes of these noisy miner removals have varied substantially, so identifying the circumstances under which they ar...
The crucial roles of biodiversity in agriculture - a necessary understanding if agirculture is to become more sustainable.
The linkages between agriculture and biodiversity - an imperative for understanding sustainable food production
Setting aside private land is an essential component of the biodiversity crisis response. In Brazil, landowners are required to have Legal Reserves (LR) (20%–80% of their property set aside for native vegetation) which, if degraded, need to be restored. Alternatively, landowners can compensate for an LR deficit by purchasing surplus credits. Each l...
Despite substantial conservation efforts, the loss of ecosystems continues globally, along with related declines in species and nature’s contributions to people. An effective ecosystem goal, supported by clear milestones, targets and indicators, is urgently needed for the post-2020 global biodiversity framework and beyond to support biodiversity co...
The imperative of a global transition to renewables to achieve net-zero emissions by 2050 calls for an examination of the associated biodiversity risks. Hydropower is the biggest source of renewable energy globally, and its remaining untapped potential is concentrated in low and lower-middle income countries which are also among the world’s most bi...
Increasingly, government and corporate policies on ecological compensation (e.g. offsetting) are requiring ‘net gain’ outcomes for biodiversity. This presents an opportunity to align development with the United Nations Convention on Biological Diversity Post-2020 Global Biodiversity Framework’s (GBF) ambition for overall biodiversity recovery. In t...
One of the basic purposes of protected areas and other effective area-based conservation interventions is to achieve conservation impact, the sum of avoided biodiversity loss and promoted recovery relative to outcomes without protection. In the context of the Convention on Biological Diversity’s negotiations on the post-2020 Global Biodiversity Fra...
Nations of the world failed to fully achieve any of the Convention on Biological Diversity 2010 targets, and the future of biodiversity hangs in the balance. Nations must not let unambitious targets in the current draft of the Post-2020 Global Biodiversity Framework prevent them from maximizing their biodiversity-conservation actions over the next...
Bioacoustics offers new ways to monitor wildlife populations. Understanding vocal changes related to age can provide demographic data that are valuable but difficult to collect for threatened species. Here, we present the vocal signals of ontogeny and fledging in nestlings for two endangered black-cockatoos, the Kangaroo Island glossy black-cockato...
Environmental policies that require native vegetation conservation can be challenging to implement, especially in productive agricultural landscapes. In Brazil, the Brazilian Native Vegetation Protection Law mandates ‘Legal Reserves’, protected native vegetation that landowners must retain on their properties. If landowners do not have the required...
A key obstacle to wildlife conservation is a scarcity of funding. A recent paper [Courchamp, F., Jaric, I., Albert, C., Meinard, Y., Ripple, W. J., and Chapron, G. (2018). The paradoxical extinction of the most charismatic animals. PLoS Biol. 16:e2003997. doi: 10.1371/journal.pbio.2003997] illustrates how for-profit businesses' widespread use of th...
The new global biodiversity framework (GBF) being developed under the Convention on Biological Diversity must drive action to reverse the ongoing decline of the Earth's biodiversity. Explicit, measurable goals that specify the outcomes we want to achieve are needed to set the course for this action. However, the current draft goals and targets fail...
Tropical deforestation continues at high rates in many regions, but it is often reported only in terms of area lost or its impacts on high-profile threatened species. Here, we examined the impact of both past and projected future deforestation on habitat extent for the entire assemblage of forest-dependent birds across the country with the greatest...
Humanity is on a pathway of unsustainable loss of the natural systems upon which we, and all life, rely. To date, global efforts to achieve internationally-agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services, have been poorly integrated. However, these different goals all rely on preserving natur...
The upcoming Convention on Biological Diversity (CBD) meeting, and adoption of the new Global Biodiversity Framework, represent an opportunity to transform humanity's relationship with nature. Restoring nature while meeting human needs requires a bold vision, including mainstreaming biodiversity conservation in society. We present a framework that...
Ecosystem services (ESs)-the benefits provided to people by nature-are fundamental to human well-being. The sustainable provision of such services is constrained by both spatial and temporal dynamics of ES supply (S) and demand (D), but the temporal aspect is usually disregarded despite its high relevance in sustainability analyses. Here, we propos...
An amendment to this paper has been published and can be accessed via a link at the top of the paper.
The fulfilment of the benefits resulting from services provided by nature requires an integrated framework that combines appropriate ecosystem service governance with spatially explicit models of service provision.
Here, we propose using a social‐ecological network approach to develop a ‘landscape governance framework’ that identifies how different...
The conflict of large carnivores and agro-pastoral communities is a key driver of carnivore decline globally. The East African state of Uganda relies heavily on tourism as a GDP contributor and large carnivores are important for generating visitor revenue in its national parks. African leopards, spotted hyenas and African lions are three species th...
Global biodiversity policy is at a crossroads. Recent global assessments of living nature (1, 2) and climate (3) show worsening trends and a rapidly narrowing window for action. The Convention on Biological Diversity (CBD) has recently announced that none of the 20 Aichi targets for biodiversity it set in 2010 has been reached and only six have bee...
Evaluating the effectiveness of management actions for threatened species recovery is critical for adaptive management. However, decision makers frequently lack the resources and time to develop data‐driven models for rigorous monitoring and evaluation. Expert knowledge can be useful in such situations, but can be challenging to translate into spec...
Australia’s 2019–2020 mega-fires were exacerbated by drought, anthropogenic climate change and existing land-use management. Here, using a combination of remotely sensed data and species distribution models, we found these fires burnt ~97,000 km2 of vegetation across southern and eastern Australia, which is considered habitat for 832 species of nat...
ContextUnderstanding how landscape fragmentation affects functional diversity, defined as the distribution of functional traits in an assemblage, is critical for managing landscapes for biodiversity and ecosystem functions. Despite some scattered evidence, we lack a clear understanding of how patterns of fragmentation drive changes in functional di...
Humanity will soon define a new era for nature-one that seeks to transform decades of underwhelming responses to the global biodiversity crisis. Area-based conservation efforts, which include both protected areas and other effective area-based conservation measures, are likely to extend and diversify. However, persistent shortfalls in ecological re...
Suppressing expert knowledge can hide environmentally damaging practices and policies from public scrutiny. We surveyed ecologists and conservation scientists from universities, government, and industry across Australia to understand the prevalence and consequences of suppressing science communication. Government (34%) and industry (30%) respondent...
Estimating the effectiveness of protected areas (PAs) in reducing deforestation is useful to support decisions on whether to invest in better management of areas already protected or to create new ones. Statistical matching is commonly used to assess this effectiveness, but spatial autocorrelation and regional differences in protection effectivenes...
