The Species Threat Abatement and Restoration (STAR) metric is a science-based tool designed to measure, in a spatially explicit way, the potential reduction in species global extinction risk that could be achieved through conservation action and restoration.
Built on data from the IUCN Red List of Threatened Species™, STAR quantifies how much global species extinction risk could be lowered through actions taken at a particular site or collection of sites, such as a company’s footprint, or even an entire country.
STAR provides a consistent approach to set extinction risk reduction targets both locally and globally, transparently making progress measurable and comparable.
STAR is available through IBAT's Estimated Species report and will be highly relevant for organisations contributing towards the KMGBF, as well as those setting science-based targets for nature.
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
IBAT guidance on how to use STAR and the IBAT Estimated Species report is below. Additionally, IBAT Alliance partner IUCN recently launched the Rapid High-Integrity Nature-positive Outcomes (RHINO) approach to help guide organisations in their interventions to deliver Nature Positive outcomes now. RHINO offers guidance and case study examples on how to use the Species Report as part of your nature-positive journey. Click here to learn more.
