What does 10 dugong deaths between 2015 and 2022 signal?

Question

Accepted Answer

The 10 dugong deaths between 2015 and 2022 signal a threat to the dugong population and its seagrass habitat.

The observed trend of approximately 10 dugong deaths, particularly among young animals, between 2015 and 2022 indicates a significant threat to the survival of the dugong species in Peninsular Malaysia. This situation also points to a broader concern for the health of their essential seagrass habitat.
Dugong Deaths and Population Concerns

Between 2015 and 2022, approximately 10 dugongs, with a notable number being young animals, have died. While precise population figures for the Mersing Islands are unavailable, the MareCet Research Organisation estimates the total dugong population in the area to be under 100. This ongoing mortality trend suggests a dwindling population, raising concerns about the long-term viability of dugongs in the region.
Importance of Seagrass Habitat

The seagrass meadows in Johor, specifically around Pulau Sibu and Pulau Tinggi, serve as critical grazing areas for dugongs. Evidence of grazing has been consistently observed in surveys since 2014. These fertile seagrass ecosystems are not only vital for the survival of dugongs but also support other commercial species, such as the 'mabang' squid, which use these waters for spawning.
Marine Park Limitations

Although the waters of Pulau Sibu and Pulau Tinggi are gazetted as a Marine Park, a significant portion of the dugong population, approximately 62%, is found outside its boundaries. Most mother-and-calf pairs have been observed outside the designated Marine Park area, indicating that current protected zones may not fully encompass the essential habitats required for the dugongs' life cycle and foraging needs.
