The majority of vulnerability assessments biodiversity to global changes have so far been applied to, and designed for, mainland systems, overlooking islands. However, islands harbour unique are epicentres ongoing extinctions. We thus introduce a specific framework for quantifying the terrestrial insular biota multiple threats. This uses markers exposure, sensitivity, adaptive capacity account characteristics island biodiversity. Our assessment involves five steps: (1) defining scope assessment, (2) selecting most appropriate markers, (3) computing metric, (4) evaluating uncertainties, (5) providing recommendations conservation. development this tailored systems is part larger initiative meet international policy targets that better integrate threats dimensions. discuss need urgency applying guide evidence-based decisions conservation biodiversity, increased attention at science-policy interface.
