As well as assessing newly recognized species, the IUCN Red List also re-assesses the status of some existing species, sometimes with positive stories to tell. For example, good news such as the downlisting (i.e. improvement) of a number of species on the IUCN Red List categories scale, due to conservation efforts. The bad news, however, is that biodiversity is declining. Currently there are more than 105,700 species on The IUCN Red List, with more than 28,000 species threatened with extinction, including 40% of amphibians, 34% of conifers, 33% of reef building corals, 25% of mammals and 14% of birds.']]> This map shows the global proportion of plant species endangered in 2019.

Data sources
This map uses data by IUCN Red List (last accessed July 2019). We aim to map as complete data as possible and therefore estimate data for missing values. In some cases, missing data for very small territories is not used in the cartogram and that area is therefore omitted in the map.

Further notes on the data, as well as all modifications to the original data source are noted in our data sheets.

[...] Gross primary production (GPP), shown here, is the total amount of carbon dioxide 'fixed' by land plants per unit time through the photosynthetic reduction of CO2 into organic compounds." Quoted from Gough, C.M. (2011) Terrestrial Primary Production: Fuel for Life, Nature Education Knowledge 3(10):28. Read more and see an animated version of this map in our blog]]> This map shows the land surface resized according to its annual gross primary production (GPP) in terms of their carbon currency (g C m-2). Each transformed grid cell in the map is proportional to the total annual production in that area which is also indicated through the colours that are overlaid. GPP is the net amount of energy that is produced by the main energy producers of an ecosystem.
Production is determined by first computing a daily net photosynthesis value which is then composited over an 8-day interval of observations for a year.

Data sources
This map uses satellite-derived cumulative composite Gross Primary Production values from NASA’s Moderate Resolution Imaging Spectroradiometer (MOD17) at 1km resolution (accessed June 2018).
