Population of dugong in Indonesia: 10.000 before 1990 (Compost, 1980) 1.000 after 1990 (de Iongh, 1993) now ? IUCN: Vulnerable
Decreasing population of dugong species biology and external threats.

Species biologyReproduction rate very low (5 %/year).The females do not bear their first calf until they are
at least 10 and up to 17 years old. Gestation lasts about 13-15 months. The calf suckles for 14-18 months.Seagrass dependent

Conservation initiatives in Indonesia ?1. Habitat protection2. Education : public awareness (National-, local- and
community levels)3. Ecotourism4. Research and monitoring

Swimming with dugong Diving with dugong
Ecotourism (?)
Dugong as a tourist attraction: dugong watching
Effect of these activities on the animals is unknown (need to be investigated)

Dugong as meat vs as tourist attraction
As a meat Rp. 6.000.000.- for one family, one week.As a tourist attraction more than Rp. 6.000.000.-
for many families and last longer.

The presence of seagrasses and dugong by interviewing local people/fishermen
Prof. H. Marsh (Dugong expert) her presentation in Srilanka, October 2015.
How many dugongs are there?•Ask the fishers?•Vessel surveys?•Aerial surveys?•Mark-recapture studies?
How are your dugongs doing?•Ask the fishers?•Conduct vessel/aerial surveys over time?•Calf counts?•Genetic studies?•Health assessments?
Where are the dugong hotspots?•Ask the fishers?•Conduct vessel/aerial surveys?•Satellite tracking?•Acoustic surveys?

Doing research on dugong is very difficult and very risky, as you can only spot them
from the air (Adulyanukosol, 2007)
Most of the pictures are from Thailand, only 1 picture in Indonesia

Conclusion GEF-Abu Dhabi dugong project is only as a trigger
to conserve dugong from extinction in Indonesian waters.
Cooperation between the relevant agencies (MMAF, LIPI, WWF, Universities i.e. IPB, UNHAS, UNSRAT, Private sectors, etc) to work together in efforts to create dugong conservation for the public welfare.
