Description
of site:
|
A permanent freshwater swamp in Kron Trai Wildlife Sanctuary, on the border between Phu Khanh Province and the high plateau (Tay Nguyen) provinces of Gia Lai-Kontum and Dak Lak. The water supply appears to come from the nearby Ba River. |
|
Climatic
conditions:
|
Tropical monsoonal climate with an average annual rainfall of 1,300-1,400 mm, a mean annual temperature of 26.4°C and a mean relative humidity of 83%. |
|
Principal
vegetation:
|
The swamp supports an abundant growth of reeds and other aquatic plants. Some rice is grown in adjacent areas. The surrounding forests of the wildlife sanctuary are dominated by species of Lagerstroemia and Dipterocarpus and associated species such as Cratocylon sp and Acanthus sp. |
|
Land
tenure:
|
Owned by Tay Son District. |
|
Conservation
measures taken:
|
The swamp is protected within the Kron Trai Wildlife Sanctuary (20,000 ha). The local people, especially the inhabitants of Bung and Bai villages, have been exposed to environmental education and are conscious of the need to conserve their natural resources. As a consequence, there is now little illegal bunting in the area. |
|
Conservation
measures proposed:
|
|
|
Land
use:
|
The entire swamp is used for the natural production of crocodiles for meat and hides. The swamp also provides water for irrigating adjacent rice paddies. |
|
Possible
changes in land use:
|
Crocodile hunting causes considerable disturbance to wildlife, and there is a possibility that the crocodiles are being over-exploited. The principal threat elsewhere in the wildlife sanctuary is shifting agriculture. |
| Disturbances and threats: | Crocodile hunting causes considerable disturbance to wildlife, and there is a possibility that the crocodiles are being over-exploited. The principal threat elsewhere in the wildlife sanctuary is shifting agriculture. |
| Economic and social values: | The swamp provides water for irrigation during the dry season, and supports a small crocodile industry. |
| Fauna: | Ban
Sau (which translates as "Crocodile Swamp") supports a population
of about 200 Siamese Crocodiles Crocodylus siamensis, a species listed
as endangered in the IUCN Red Data Book and now extinct in the wild throughout
most of its former range. Other reptiles include Gekko gekko and
many species of snake. The swamp is very important for waterbirds, particularly during the dry season when all other swamps in the region have dried out. Waterfowl recorded in recent years include Phalacrocorax carbo, Ixobrychus cinnamomeus, Egretta alba, Ardea cinerea, Dendrocygna javanica, Anas querquedula, Amaurornis phoenicurus, Gallicrex cinerea, Gallinula chioropus, Vanellus duvaucelii and Gallinago gallinago. The surrounding forests are rich in bird life and support a variety of larger mammals including Nycticebus coucang, Selenarctos thibetanus, Felis temmincki, Panthera tigris, P. pardus, Cervus unicolor, Bos gaurus, Capricornis sumatraensis and Manis pentadactyla. |
