Abstract Fucus virsoides is a glacial relict-species endemic to the Adriatic that was widespread from northern Italy southern Albania. In recent decades, however, it has suffered an alarming decline. this study, all available records were reviewed reconstruct its historical and current occurrence investigate possible causes of Comprehensive mapping revealed continuing decline with significant shift, leaving only about 20 fragmented populations. While species already classified as critically endangered in Albania, F. could be considered functionally extinct Istria (Croatia), threatened extinction Montenegro locally Slovenia. The status rest Croatia still unclear. remaining populations are located areas characterised by low temperatures, salinity high nutrient concentrations. Long-term analyses these key abiotic factors profound changes suggest link species' This study provides thorough assessment overall argues for inclusion on IUCN Red List. Immediate conservation measures needed long-term survival species.
