At Son Tra Nature Reserve:
Since 2007, the DLF has supported a professional staff of Vietnamese biologists and botanists who collect field observations on the douc diet, behavior and ecology all year. These studies are providing the first long term data on various aspects of behavior by all members of the group. Our botanist has been documenting the characteristics of all plants the doucs’ utilize. In addition, the chemical properties of all foods consumed are being analyzed.

In addition to the study of feeding ecology, we are tracking group composition throughout the year and have found that douc groups vary in numbers from one season to another. We continue to document the reproduction and development of doucs at Son Tra Nature Reserve.

At Chu Mom Ray National Park:
The DLF has conducted four extensive surveys to delimit the populations of doucs and gibbons. These surveys formed the foundation of the successful snare and trap and conservation actions at the national park. This year a major grant will support the first long term monitoring of the douc and gibbon populations.
