| Status of development |
For extinction risk trends: available for birds, mammals, and amphibians globally; further taxonomic groups being added over the next decade (e.g., sharks, groupers and wrasses, cycads, conifers, corals etc). Available globally, regionally and, over the next decade, nationally (many countries have produced national Red Lists (some using the IUCN methodology and others not) which when repeated could produce national RLIs). For population trends, available for vertebrates globally. Trends in the status of utilized species can be used as a surrogate for impacts of unsustainable utilization on species, although many are impacted by other threats too. Extinction risk indicators and population trend indicators are complementary because they measure different levels of biodiversity (species vs populations), have different levels of sensitivity (high for population trends, moderate for extinction risk) and different levels of geographic & species coverage (comprehensive for extinction risk for a number of taxonomic groups; much lower for population trends, which are based on better studied species). |

| Data Sources |
Global IUCN Red List. National red lists (either those that apply IUCN criteria and guidelines at the sub-global level, or from other risk-ranking protocols). Living Planet Index database. |
| Data Requirements |
IUCN Red List categories for complete sets of species from two or more time-points. Requires genuine recategorisations to be distinguished from non-genuine changes following standard protocols. For population trends, requires population time-series. PLUS for both, requires identification of which species are utilized (included which are traded). |
| Who's responsible for measuring? |
IUCN and its Partners (BirdLife InteR, National, NatureServe, Conservation InteR, National, Kew etc) at the global level. National agencies developing or updating national red lists. ZSL/WWF for LPI. |
| Other conventions/processes using indicator |
