Dugong conservation status, estimated numbers and threats in the Pacific Basin Dugong movement and connectivity Advances in some key monitoring tools Matthieu Juncker
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

Heterogeneous movements Possible long-range migratory patterns in some locations movements more likely response to climatic events Local-scale seasonal adjustments in habitat use in locations Movement behaviour adjusted to small coral reef lagoon habitats Dugong movements and connectivity Dugongs’ long distance journeys have led to species range ...

New insights into the long-term/range movements (GPS-sat tags) and short-term, fine scale dive profiles Require animal capture: logistically challenging if not impossible in low dugong density areas. Risky, and need to be culturally acceptable GPS-Iridium or Diary and cam-diary tags ✪ ✪
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...
Mar 5, 2024 · We conducted local-scale. aerial surveys to document the seasonal and tidal changes in the distribution and number of dugongs over seagrass and non-seagrass coral reef habitats in a small lagoon in New Caledonia. The surveys were conducted fortnightly over 18 months in different seasons and at different tides.
Aug 21, 2020 · Dugongs are found in the waters of the West Pacific across nearly 40 countries and 57,000 miles of coastline. The largest populations are found in wide, shallow, protected coastal areas such as estuaries, bays, and mangroves.
