Abstract Translocation is a core conservation strategy, yet the outcomes of invertebrate translocations are often poorly documented due to the small size and limited mobility of invertebrates. Levels of genetic diversity and inbreeding are key indicators of translocation success, reflecting breeding success, adaptive capacity, and long‐term viability of translocated populations. This study characterizes the genetic diversity of a recently translocated flightless grasshopper, Vandiemenella viatica , two generations after release. Genome‐wide sequence data revealed significant reductions in observed heterozygosity (19.07% decrease) and nucleotide diversity (12.69% decrease) in the F 2 generation relative to the source population. Runs of homozygosity were 50.74% more common and 112.98% longer in the F 2 generation relative to the source population. These rapid reductions in diversity underscore the need for genetic monitoring to be integrated into translocation protocols to inform management actions like genetic supplementation for improved conservation outcomes.
