Abstract We assess progress toward the protection of 50% of the terrestrial biosphere to address the species-extinction crisis and conserve a global ecological heritage for future generations. Using a map of Earth's 846 terrestrial ecoregions, we show that 98 ecoregions (12%) exceed Half Protected; 313 ecoregions (37%) fall short of Half Protected but have sufficient unaltered habitat remaining to reach the target; and 207 ecoregions (24%) are in peril, where an average of only 4% of natural…

Informing Canada’s commitment to biodiversity conservation: A science-based framework to help guide protected areas designation through Target 1 and beyond
Biodiversity is intrinsically linked to the health of our planet—and its people. Yet, increasingly, human activities are causing the extinction of species, degrading ecosystems, and reducing nature’s
Area-based conservation in the twenty-first century.
TLDR
To be more successful after 2020, area-based conservation must contribute more effectively to meeting global biodiversity goals-ranging from preventing extinctions to retaining the most-intact ecosystems-and must better collaborate with the many Indigenous peoples, community groups and private initiatives that are central to the successful conservation of biodiversity.
A Global Deal For Nature: Guiding principles, milestones, and targets
TLDR
Freshwater and marine targets included here extend the GDN to all realms and provide a pathway to ensuring a more livable biosphere.
A global-level assessment of the effectiveness of protected areas at resisting anthropogenic pressures
TLDR
This analysis of protected areas across 152 countries finds that compared with matched unprotected areas, PAs have on average not reduced a compound index of pressure change over the past 15 y, and cautions against the rapid establishment of new PAs without simultaneously addressing the conditions needed to enable their success.
Designing an ecologically representative global network of protected areas requires coordination between countries
People are now impacting the natural environment at an unparalleled scale. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) warns that up to one million
Managing the middle: A shift in conservation priorities based on the global human modification gradient
TLDR
A cumulative measure of human modification of terrestrial lands based on modeling the physical extents of 13 anthropogenic stressors and their estimated impacts using spatially explicit global datasets with a median year of 2016 suggests that most of the world is in a state of intermediate modification and moderately modified ecoregions warrant elevated attention.
Reconciling global priorities for conserving biodiversity habitat
TLDR
This work integrates fine-resolution global data on habitat condition and species assemblage turnover, to identify Earth’s high-value biodiversity habitat, which are areas in better condition than most other locations once supporting a similar assemblages of species, and are found within both intact regions and human dominated landscapes.
Terrestrial conservation opportunities and inequities revealed by global multi-scale prioritization
TLDR
This multi-scale linear optimization approach delineates globally the areas required to meet conservation targets for all ∼32,000 described terrestrial vertebrate species, while offering flexibility in decision management to meet different local conservation objectives.

Terrestrial Ecoregions of the World: A New Map of Life on Earth
TLDR
This article has developed a detailed map of the terrestrial ecoregions of the world that is better suited to identify areas of outstanding biodiversity and representative communities and addresses the disparity in resolution between maps currently available for global conservation planning and the reality of the Earth’s intricate patterns of life.

Protected areas’ role in climate-change mitigation
TLDR
It is projected that rapid climate change, similar to high-end projections in IPCC’s Fifth Assessment Report, would cause the annual carbon sequestration rate in protected areas to drop to about 0.3 Pg C by 2100, which is about one fifth of the carbon sequestered by all land ecosystems annually.

Sixteen years of change in the global terrestrial human footprint and implications for biodiversity conservation
TLDR
This work uses recently available data on infrastructure, land cover and human access into natural areas to construct a globally standardized measure of the cumulative human footprint on the terrestrial environment at 1 km2 resolution from 1993 to 2009.
The worldwide costs of marine protected areas.
TLDR
An estimate of the costs of a global MPA network is provided, based on a survey of the running costs of 83 MPAs worldwide, that a global network meeting the World Parks Congress target of conserving 20-30% of the world's seas might cost between 5 and 19 billion US dollars annually to run and would probably create around one million jobs.

TLDR
The criteria address the two key issues for setting site conservation priorities: vulnerability and irreplaceability and propose quantitative thresholds for the identification of KBAs meeting each criterion, based on a review of existing approaches and ecological theory to date.
