The IUCN Green List of Protected and Conserved Areas is the first global standard of best practice for area-based conservation. It is a programme of certification for protected and conserved areas – national parks, natural World Heritage sites, community conserved areas, nature reserves and so on – that are effectively managed and fairly governed. By giving recognition to well-managed and well-governed protected and conserved areas, the IUCN Green List aims to increase the number of natural areas delivering long-lasting conservation results for people and nature.

IUCN has developed this standardized methodology for Conservation Outlook Assessments of natural World Heritage sites.

BirdLife International has developed this global framework for monitoring the conservation status of, threats to, and conservation actions at IBAs.

The Enhancing our Heritage (EoH) Toolkit contains twelve practical tools for assessing the management effectiveness of natural World Heritage sites.
