Tools in this family synthesise and assess knowledge relative to status, function, and drivers of nature, nature’s contributions to people, human well-being, and the connections between these. These include scenarios, management effectiveness evaluations, quantitative modelling, cost–benefit analysis, and trade-off analysis.

IUCN Red List of Ecosystems

The IUCN Red List of Ecosystems Categories and Criteria is a global standard for how we assess the conservation status of ecosystems, applicable at local, national, regional and global levels. The Red List of Ecosystems evaluates whether ecosystems have reached the final stage of degradation (a state of Collapse), whether they are threatened at Critically Endangered, Endangered or Vulnerable levels, or if they are not currently facing significant risk of collapse (Least Concern).

IUCN Red List of Threatened Species

The IUCN Red List of Threatened Species™ is the most comprehensive, objective database of the global conservation status of species. It evaluates the extinction risk of thousands of species and subspecies. The IUCN aims to have each species re-evaluated in a peer reviewed manner every five years if possible, or at least every ten years. It provides information about range, population size, habitat and ecology, use, trade, threats, and conservation actions.
