This table provides metadata for the actual indicator available from Ghana statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Ghana statistics, this table should be consulted for information on national methodology and other Ghana-specific metadata information.
Goal 15: Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss
Target 15.5: Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species
Indicator 15.5.1: Red List Index
|Definition and concepts||
The Red List Index measures change in aggregate extinction risk across groups of species. It is based on genuine changes in the number of species in each category of extinction risk on The IUCN Red List of Threatened Species expressed as changes in an index ranging from 0 to 1.
Threatened species are those listed on The IUCN Red List of Threatened Species in the categories Vulnerable, Endangered, or Critically Endangered (i.e., species that are facing a high, very high, or extremely high risk of extinction in the wild in the medium-term future).
Changes over time in the proportion of species threatened with extinction are largely driven by improvements in knowledge and changing taxonomy. The indicator excludes such changes to yield a more informative indicator than the simple proportion of threatened species. It therefore measures change in aggregate extinction risk across groups of species over time, resulting from genuine improvements or deteriorations in the status of individual species.

Resource Management Support Centre (RMSC), 2020
Ghana’s Sustainable Development Goals (SDGs) Report, 2020
Forestry Commission of Ghana (FC)
National Development Planning Committee (NDPC)
This indicator can be used to assess overall changes in the extinction risk of groups of species as a result of these threats and the extent to which threats are being mitigated. The Red List Index value ranges from 1 (all species are categorized as ‘Least Concern’) to 0 (all species are categorized as ‘Extinct’), and so indicates how far the set of species has moved overall towards extinction. An upward global Red List Index trend would indicate that the SDG Target 15.5 of reducing the degradation of natural habitats and protecting threatened species is on track. A global Red List Index value of 1 would indicate that biodiversity loss has been halted.
