Many global environmental agendas, including halting biodiversity loss, reversing land degradation, and limiting climate change, depend upon retaining forests with high ecological integrity, yet the scale and degree of forest modification remain poorly quantified and mapped. By integrating data on observed and inferred human pressures and an index of lost connectivity, we generate a globally consistent, continuous index of forest condition as determined by the degree of anthropogenic…

Limited protection and ongoing loss of tropical cloud forest biodiversity and ecosystems worldwide
TLDR
A global assessment of the status of tropical cloud forests shows that they have declined overall by ~2.4% since 2001, with much of this occurring despite formal protection and with up to 8% loss in some regions.
Limiting the loss of terrestrial ecosystems to safeguard nature for biodiversity and humanity
TLDR
This work found that at least 67 million km2 of Earth’s natural terrestrial ecosystems require retention – via a combination of strict protection but more prominently through sustainably managed land use regimes complemented by restoration actions – to contribute to biodiversity, climate, soil and freshwater objectives under four United Nations’ Resolutions.
Reforestation enhanced landscape connectivity for thermal buffering in China
Deforestation-induced landscape fragmentation causes habitat loss and isolation, modifies local climate, and therefore threatens biodiversity. While, on the contrary, how large-scale reforestation…
Where Might We Find Ecologically Intact Communities?
Conservation efforts should target the few remaining areas of the world that represent outstanding examples of ecological integrity and aim to restore ecological integrity to a much broader area of…
Maximizing the effectiveness of national commitments to protected area expansion for conserving biodiversity and ecosystem carbon under climate change
TLDR
A case study for endangered species planning for old-forest-associated species in the US Pacific Northwest demonstrates how regional planning can be nested hierarchically within national biodiversity-focused adaptation and nature-based mitigation strategies which integrate refugia, connectivity, and ecosystem carbon metrics.
Southeast Asian protected areas are effective in conserving forest cover and forest carbon stocks compared to unprotected areas
TLDR
This study is the first to find that METT scores could predict the level of carbon emissions avoided in protected areas, and illustrates the need to scale-up protected area management effectiveness reporting programs to improve their effectiveness for conserving forests, and for storing and sequestering carbon.
Drought-driven wildfire impacts on structure and dynamics in a wet Central Amazonian forest
TLDR
Fire impacts are weaker in the wetter Amazon and trees of greater sizes and higher wood densities may confer a margin of fire resistance; however, this may not extend to higher intensity fires arising from climate change.
Toward monitoring forest ecosystem integrity within the post‐2020 Global Biodiversity Framework
Signatory countries to the Convention on Biological Diversity (CBD) are formulating goals and indicators through 2050 under the post-2020 Global Biodiversity Framework (GBF). Among the goals is…
Past and Future of Temperate Forests State under Climate Change Effects in the Romanian Southern Carpathians
Research Highlights: Carpathian forests hold high ecological and economic value while generating conservation concerns, with some of these forests being among the few remaining temperate virgin…
Scientific foundations for an ecosystem goal, milestones and indicators for the post-2020 global biodiversity framework.
TLDR
Science-based goals, supported by well-formulated action targets and fit-for-purpose indicators, will provide the best foundation for reversing biodiversity loss and sustaining human well-being.

The exceptional value of intact forest ecosystems
TLDR
It is argued that maintaining and, where possible, restoring the integrity of dwindling intact forests is an urgent priority for current global efforts to halt the ongoing biodiversity crisis, slow rapid climate change and achieve sustainability goals.
The last frontiers of wilderness: Tracking loss of intact forest landscapes from 2000 to 2013
TLDR
It is shown that global IFL extent has been reduced by 7.2% since the year 2000, largely driven by the tripling of IFL tropical forest loss in 2011–2013 compared to that in 2001–2003.
Anthropogenic disturbance in tropical forests can double biodiversity loss from deforestation
Concerted political attention has focused on reducing deforestation, and this remains the cornerstone of most biodiversity conservation strategies. However, maintaining forest cover may not reduce…
Primary forests are irreplaceable for sustaining tropical biodiversity
TLDR
It is found that biodiversity values were substantially lower in degraded forests, but that this varied considerably by geographic region, taxonomic group, ecological metric and disturbance type.
Spatial priorities for conserving the most intact biodiverse forests within Central Africa
The forests of Central Africa contain some of Earth's few remaining intact forests. These forests are increasingly threatened by infrastructure development, agriculture, and unsustainable extraction…
Global forest loss disproportionately erodes biodiversity in intact landscapes
TLDR
Deforestation substantially increased the odds of a species being listed as threatened, undergoing recent upgrading to a higher threat category and exhibiting declining populations, and it was shown that these risks were disproportionately high in relatively intact landscapes.
Importance of Indigenous Peoples’ lands for the conservation of Intact Forest Landscapes
Intact Forest Landscapes (IFLs) are critical strongholds for the environmental services that they provide, not least for their role in climate protection. On the basis of information about the…
Forest Loss in Protected Areas and Intact Forest Landscapes: A Global Analysis
In spite of the high importance of forests, global forest loss has remained alarmingly high during the last decades. Forest loss at a global scale has been unveiled with increasingly finer spatial…
Global humid tropics forest structural condition and forest structural integrity maps
TLDR
Two data products are introduced to meet the need for structurally complex forests with low human pressure in the humid tropics, and represent an important step in maturation from conservation focus on forest extent to forest stands that should be considered “best of the last” in international policy settings.
Wilderness areas halve the extinction risk of terrestrial biodiversity
TLDR
The persistence probability of biodiversity is modeled, combininghabitat condition with spatial variation in species composition, to show that retaining these remaining wilderness areas is essential for the international conservation agenda.
