T tapestry of life on Earth is unraveling as humans increasingly dominate and transform natural ecosystems. Scarce resources and dwindling time force conservationists to target their actions to stem the loss of biodiversity— a pragmatic approach, given the highly uneven distribution of species and threats (Soulé and Kohm 1989, Olson and Dinerstein 1998, Mace et al. 2000, Myers et al. 2000). Unfortunately, the ability to focus strategically is hindered by the absence of a global biodiversity map… 

The Global 200: Priority ecoregions for global conservation

A global strategy to conserve biodiversity must aim to protect representative examples of all of the world's ecosystems, as well as those areas that contain exceptional concentrations of species and endemics, to conserve the most outstanding and representative habitats for biodiversity.

Mapping More of Terrestrial Biodiversity for Global Conservation Assessment

A new approach to describing and mapping the global distribution of terrestrial biodiversity that focuses on estimating spatial pattern in emergent properties of biodiversity (richness and compositional turnover) rather than distributions of individual species, making it well suited to lesser-known, yet highly diverse, biological groups.

A global test of ecoregions

It is concluded that ecoregion-based conservation planning can guide investments that simultaneously protect species-, community- and ecosystem-level biodiversity, key for securing Earth’s life support systems into the future.

Using the IUCN Red List to map threats to terrestrial vertebrates at global scale

This work uses expert-derived information from the International Union for Conservation of Nature Red List on threats to 23,271 species, representing all terrestrial amphibians, birds and mammals, to generate global maps of the six major threats to these groups.

The Impact of Conservation on the Status of the World’s Vertebrates

Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.

Freshwater Ecoregions of the World: A New Map of Biogeographic Units for Freshwater Biodiversity Conservation

Preliminary data for fish species compiled by ecoregion reveal some previously unrecognized areas of high biodiversity, highlighting the benefit of looking at the world's freshwaters through a new framework.

Temporally inter-comparable maps of terrestrial wilderness and the Last of the Wild

The most up-to-date temporally inter-comparable maps of global terrestrial wilderness areas are presented, which are essential for monitoring changes in their extent, and for proactively planning conservation interventions to ensure their preservation.

Intact Faunal Assemblages in the Modern Era

The results indicate that although protected areas are in some cases associated with the prevention of extinctions, there are many regions in which human activity coexists with intact vertebrate assemblages and several regions that are not represented in other prioritization metrics are identified.

Hotspots and ecoregions: a test of conservation priorities using taxonomic data

The loss of biodiversity is now recognized as a global problem of significant magnitude [ Science 289: 2279]. Conservation efforts focus on measuring species diversity and distribution, assessing

The authors discuss the wider conservation relevance of EBAs, including why birds are good indicators of biodiversity, and how EBAs can be used effectively to influence policy-makers.

Toward a Blueprint for Conservation in Africa

I the last two decades, various quantitative techniques for assessing conservation priorities have been developed, based on data about the distribution of species (Reid 1998, Williams 1998, Margules

Mapping biodiversity value worldwide: combining higher-taxon richness from different groups

Maps of large-scale biodiversity are urgently needed to guide conservation, and yet complete enumeration of organisms is impractical at present. One indirect approach is to measure richness at higher

Flagship species, ecological complementarity and conserving the diversity of mammals and birds in sub‐Saharan Africa

In order to succeed in representing many mammals and birds in area selection, it is not sufficient for the groups used for selection to occur in many different eco-regions, they must also have low overlaps in distribution so as to provide high ecological complementarity.
