The Data

Caracol State Park
National Park
World Database on Protected Areas

We host and maintain the three key global biodiversity datasets

Logo for IUCN Red List of Threatened Species

IUCN Red List of Threatened Species

The IUCN Red List of Threatened Species (also known as the IUCN Red List) is a rich compendium of information on threats, ecological requirements, and habitats of over 147,517 species; and on conservation actions that can be taken to reduce or prevent extinctions. It is based on an objective system for assessing the risk of extinction of a species based on past, present, and projected threats. Species assessments are conducted following a standardized process using the rigorous IUCN Red List Categories and Criteria, ensuring the highest standards of scientific documentation, information management, expert review, and justification. IUCN aims to re-evaluate the IUCN Red List category of species every five to ten years to monitor change.

World Database on Protected Areas

The World Database on Protected Areas (WDPA) is a joint project between UN Environment Programme and the International Union for Conservation of Nature (IUCN), managed by UN Environment World Conservation Monitoring Centre. Data for the WDPA is collected from international convention secretariats, governments, and collaborating NGOs. The WDPA uses the IUCN definition of a protected area as the main criteria for entries included in the database.

Logo for World Database of Key Biodiversity Areas

World Database of Key Biodiversity Areas

Key Biodiversity Areas (KBA) are 'sites contributing significantly to the global persistence of biodiversity’, in terrestrial, freshwater and marine ecosystems. Sites qualify as global KBAs if they meet one or more of 11 criteria, clustered into five categories: threatened biodiversity; geographically restricted biodiversity; ecological integrity; biological processes; and, irreplaceability. The World Database of Key Biodiversity Areas is managed by BirdLife International on behalf of the KBA Partnership.

Derived Data

The Species Threat Abatement and Restoration Metric data layer

Raster data underpinning the STAR Metric in IBAT are also available to download via PAYG or subscription options. STAR scores for any terrestrial 5x5km grid cell provide an indication of the relative potential contribution to reducing species extinction risk through either threat abatement or restoration activities. STAR scores are derived based on a species’ current and restorable Area of Habitat (AOH). Terrestrial scores are currently calculated for species of amphibians, birds and mammals for which current or historical AOH are available.

Rarity-weighted species richness

The rarity-weighted richness map is a raster layer showing the relative importance of each ~10km (30 arc-seconds) grid cell in terms of its aggregate contribution to the global distribution of species of mammals, birds, amphibians, crabs, crayfishes and shrimps. High values show that a cell holds a large number of species and/or that the average ranges of the species present in the cell are small, so that the cell represents a relatively high proportion of their range. Rarity-weighted richness is also known as ‘range-size rarity’ or ‘range-rarity’, and has been used as a metric of ‘biodiversity significance', as well as feeding into the Biodiversity Impact Metric.

IBAT uses the most up to date information from each of these datasets to ensure the information our customers are accessing accurately reflects our ever-changing world. Over US$6.5 million is invested each year to update and maintain these databases.
