Reconciling Different Forms of Ecological Integrity to Aid the Kunming-Montreal Global Biodiversity Framework

Abstract

With the Kunming-Montreal Global Biodiversity Framework (GBF), the international community has committed to retaining ecosystems of high ecological integrity. Monitoring progress toward this target requires the identification of suitable indicators, but these are not universally recognized. In this study, we analyze available global maps of terrestrial ecological integrity and evaluate their representation of different dimensions of integrity (structure, composition, and function). Although 73% of terrestrial surface holds conservation value according to at least one map, less than 1% of land attains high integrity according to all of them. Solely relying on one indicator map risks overlooking the integrity value of at least 41 million km² of land, with some key areas for biodiversity conservation inadequately represented by these indicators of integrity. However, when used in combination, complementary dimensions of integrity help identify an area covering 41.1% of the terrestrial surface, two-thirds requiring urgent conservation action. The synergistic use of existing measures offers considerable potential to guide the implementation of Target 1 of the GBF while supporting more equitable conservation paradigms. Developing robust indicators and understanding the link among different ecological dimensions is essential to protect ecosystems of high ecological integrity in the long term.
