| Operational Classification |
Priority and ready for use globally |
| Status of development |
Could be rapidly generated for marine vertebrates globally. Under development for seabird bycatch species. Could be developed for other taxa. 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). |
