STAR (Species Threat Abatement and Restoration Metric) allows organisations to quantify the potential contributions that species threat abatement and restoration activities offer towards reducing extinction risk across the world.
The Species Threat Abatement and Restoration Metric (STAR) is a raster data layer and IBAT Report derived from the IUCN Red List of Threatened Species™.
For the first time, STAR allows organisations to quantify the potential contributions that species threat abatement and restoration activities offer towards reducing extinction risk across the world.
STAR shows how interventions deliver reductions in pressure that can result in changes to the Red List Index (RLI), which is used as the biodiversity indicator for the Sustainable Development Goals, the Aichi Targets and the United Nations System for Environmental-Economic Accounting.
STAR will be highly relevant for organisations contributing towards the Kunming-Montreal Global Biodiversity Framework, as well as organisations setting science-based targets for nature.
IBAT has produced an Industry Briefing Note on STAR and for more information on the calculation and interpretation of STAR, please refer to IBAT’s Business User Guidance.
STAR Scores reflect:
- The number and Red List categories of Threatened and Near-Threatened species present at a site or administrative region, and the proportion of their ranges occupied by the site. The greater the proportion of species’ ranges occupied by the site, the greater influence a project can have over the populations that live there, and the more threatened they are, the larger the potential return.
- How much each kind of pressure affects those species. The greater the potential reduction in a pressure is, the greater the potential return.
- The effectiveness with which particular pressures are reduced by interventions .
- STAR Scores represent the opportunity to reduce the threat status for species of conservation concern to the category of ‘Least Concern’ - if all species were Least Concern, the STAR score for a given area would be 0
