Genetic Indicators for Nature Monitoring



Ne is considered a key EBV for genetic diversity and is applied as a headline indicator in the Kunming-Montreal Global Biodiversity Framework, with ample scientific support. In GINAMO, we will focus on how to assess N e , even in the absence of primary genetic data. We aim to (1) develop a sound framework of practical guidelines and workflows to enable genetic EBVs and indicators to be effectively used for biodiversity monitoring, allowing policy makers and nature managers globally to assess biodiversity trends; and (2) provide a clear roadmap for the outreach (also towards to wider public), acceptance and uptake of these genetic EBVs and indicators in policy and nature management at national, transnational and international levels. We will work with the two main indicators that have been recently accepted for the Global Biodiversity Framework:
● Indicator 1, “the proportion of populations within species with a genetically effective size (Ne) greater than 500”, is targeted at conserving GD within large populations for rapid response to changing environmental conditions. Ne reflects how fast GD is lost in populations, and it influences both the risk of inbreeding and the evolutionary potential of populations. Monitoring Ne is therefore essential to understand long-term population viability.
● Indicator 2, “the proportion of populations maintained”, aims to conserve GD among populations (genetic distinctiveness) to provide diverse ‘options’ for the future adaptation of the species. This indicates maintenance of local adaptations in different populations across a range, ensuring species'
