This project delivers formal conservation assessments of bird species using internationally recognised frameworks such as the IUCN Red List and Green Status of Species. We assess extinction risk, population trends, threats and conservation actions to identify which species are most at risk and where conservation efforts are working. These assessments provide the authoritative evidence base used by government, conservation organisations and funders to prioritise action and track progress over time.
We synthesise data from citizen science, targeted surveys and expert knowledge, applying transparent and repeatable assessment methods aligned with global standards such as those put forward by the IUCN.

The IUCN Red List provides a standardised assessment of a species’ risk of extinction. It draws on evidence about population size and trends, distribution, habitat and threats to classify species in categories such as Least Concern, Vulnerable, Endangered or Critically Endangered.
The IUCN Green Status of Species complements the Red List by measuring how far a species has progressed towards full recovery across its natural range. It considers whether populations are present, viable and ecologically functional, and assesses the contribution of past conservation, dependence on continued action, and future recovery potential.
Together, Red List and Green Status assessments show where species are declining, which threats require attention and whether conservation is working. This evidence guides species and habitat priorities, management plans, policy, funding and monitoring, while providing a baseline against which progress towards recovery can be measured.
