Protecting forest ecosystems is a critical action for addressing both the climate and biodiversity crises. Effective long-term management of forests requires landscape approaches, but evaluating the management actions is a key challenge. Previous research has suggested evaluation should focus on three interrelated pillars: ecosystem integrity, effective planning, and strong governance. This paper presents a framework for evaluating ecosystem integrity based on the ‘Principle, Criteria, Indicator and Verifier’ (PCIV) method. The key principle used is ecosystem autopoiesis – the ability of a system for self-generation and maintenance by creating its own parts. Four key criteria are applied, accompanied by a set of nine indicators. Verifiers for each indicator are suggested for which feasible data sources are likely available. The use of the three-pillar framework, including ecosystem integrity, is illustrated using three hypothetical cases representing different forest landscape contexts. Such evaluation can provide practical, consistent, repeatable, and comparable information for stakeholders and decision makers.
