The Mekong River Dolphin Conservation Project was initiated in January 2001.  The primary aims of the project are to undertake a comprehensive status assessment of the Irrawaddy dolphin (Orcaella brevirostris) population that inhabits the Mekong River, develop effective conservation and management initiatives, and build capacity amongst local government officials.
Surveys indicate that the total Mekong River Irrawaddy dolphin population is small (probably no more than 100 individuals remain), and in danger of local extinction in the near future unless effective conservation measures are established and maintained.
The current mortality rates (for example, at least 11 dolphins died during 2003) and total population size indicate that the Irrawaddy dolphin could completely disappear from the Mekong River basin in the next 10-15 years.
