Long-lived and slow to mature Geographical overlap between dugongs and people put the animals at risk from a range of activities Type and intensity of threat vary with location (across and within countries)
National laws protect dugongs in the Pacific range states, but enforcement is lacking.
Status remain mostly unknown (except Australia) Several countries lack baseline data + formal assessment hasn’t really been conducted new data starting to emerge Opportunities to conduct IUCN regional assessments (IUCN Sirenia specialist group here help) Need for evidence of decline in the population

Decision support tool for research into dugongs, seagrasses and associated human communities. Developed by Dugong Technical Group. Audience: marine natural resource managers, decision-makers (government and non-government) and researchers. Purpose: standardise data sets and methods across countries for better comparison of global dugong and seagras...
The dugong (Dugong dugon) is the only herbivorous mammal that is strictly marine. It has a range spanning some 37 countries, including tropical and subtropical coastal and island waters. This plan presents a global overview of the status of the dugong and its management throughout its range.
