Loss of natural and semi-natural vegetated land is presented as a proxy for pressures on biodiversity and ecosystems. This includes tree cover, grassland, wetland, shrubland and sparse vegetation converted to any other land cover type. Gains of natural and semi-natural vegetated land are conversions in the opposite direction. The denominator used is the ‘stock' of natural and semi-natural land at the start of the period.

"Built-up area" is defined as the presence of buildings (roofed structures). This definition largely excludes other parts of urban environments or human footprint such as paved surfaces (roads, parking lots), commercial and industrial sites (ports, landfills, quarries, runways) and urban green spaces (parks, gardens).

This dataset provides country-level protected area coverage for the terrestrial and marine domains calculated from the World Database on Protected Areas (WDPA). The exclusive economic zone (EEZ) of a country extends 200 nautical miles from the coastline, or to the mid-point between coastlines where the EEZ of different countries would otherwise overlap.

Number of threatened mammal species expressed as percentage of total known species. The threatened category refers to critically endangered, endangered and vulnerable species, that is those plants and animals that are in danger of extinction or likely soon to be (for further information, see the IUCN Red List Categories and Criteria: Version 3.1, Second edition). Data refer to 2015 or latest available data.
