Restoring genetic diversity to facilitate the implementation of the EU Nature Restoration Law

Abstract

Governments and economic blocs are recognising that the world faces a biodiversity crisis. The restoration of biodiversity to the levels prior to widespread human induced damage has been incorporated as a crucial component of conservation in the Global Biodiversity Framework of the Convention of Biological Diversity. The Nature Restoration Law (NRL) forms part of the European Union's response and after its adoption by the European Parliament and the Council of the European Union, it has formally become the Nature Restoration Regulation (NRR). The NRL aims to play a role in restoring ecosystems, habitats and species but does not expressly include genetic diversity, the third biodiversity component. Considering genetic diversity in strategic biodiversity planning is important to help nature adapt to rapid anthropogenic change. We have reviewed the text of the NRL and note opportunities to incorporate genetic diversity in National Restoration Plans to augment its implementation. In particular, genetic diversity assessments are well aligned with the NRL's aspiration to enhance connectivity, and genetic indicators can assess the effectiveness of its implementation. Here we give examples where restoration has incorporated genetic diversity to ensure long term wide-reaching success. This is of relevance beyond the NRL and applies generally to policy for nature restoration efforts globally, especially those related to the Global Biodiversity Framework.
