Sep 27, 2021 · Despite legislations to forbid dugong meat consumption outside specific traditional permits, poaching persists, in New Caledonia and in many of the “low-income” countries that are home to dugongs.
Aug 25, 2021 · August 25, 2021. A close relative of the manatee found in the Indo-Pacific, dugongs are a hit for tourists and an important part of coastal marine ecosystems. But between climate change,...
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.

Mar 5, 2024 · The dynamic habitat use by dugongs (Dugong dugon) in small coral reef lagoon systems spatially limited by tides is not well understood and has hampered adaptive management. Aims. We investigated how dugongs locally used a high conservation value coral-reef lagoon system during different seasons and tides to support local management. Methods.

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

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...
Sep 14, 2023 · Dugongs can be found in warm coastal waters of the Indo-Pacific region, including the Red Sea, Indian Ocean, and the western Pacific Ocean. They are herbivorous animals that primarily feed on seagrass, which makes up a significant part of their diet. Dugongs are fascinating creatures with a rich history dating back millions of years.
Jan 13, 2023 · In the case of New Caledonia’s dugongs, a geographically and genetically isolated subpopulation, the assessment found that the number of mature dugongs is now estimated to be between 149–896 individuals, based on aerial surveys conducted from 2003 to 2012.
