Well, it depends on the taxonomic group, of course!That’s why the #ERGAcommunity is working on taxon-specific sampling procedures.

Real conservation action, guided by genomes!

Why go beyond the reference genome?
Because population genomics reveals hidden risks — low diversity, genetic drift, and declining gene flow. 🌍
Wetlands are disappearing… and so is genetic diversity.
