BirdLife Indochina Programme (BirdLife Direct Action Programme)

Site description The IBA comprises an area of seasonally inundated grassland in the floodplain of the Bassac River, which forms part of one of the largest areas of contiguous natural habitat remaining in the Mekong Delta. To the south and east, this area borders Vietnam, where the natural habitat has been almost entirely converted to agriculture. The IBA is inundated for 3 to 4 months each year, during which time a mat of floating vegetation, comprising around 30 aquatic plant species, forms. During the dry season, from December until May, the IBA supports a non-breeding population of Sarus Crane Grus antigone. After Ang Tropeang Thmor (KH001), this is the largest non-breeding population of this species known in Cambodia. The IBA also supports a number of other globally threatened and near-threatened bird species, most notably Bengal Florican Houbaropsis bengalensis. During 2002, the establishment of a Sarus Crane Conservation Area at the IBA was proposed by Department of Forestry and Wildlife.

Key Biodiversity 50 Baya Weavers, 278 Grey Herons and 25 Purple Herons were recorded in November 2001.

IBA Monitoring

2010 medium favourable high
Medium - based upon reliable but incomplete / partially representative data

Agriculture and aquaculture annual & perennial non-timber crops - small-holder farming past (and unlikely to return) and no longer limiting small area/few individuals (<10%) no or imperceptible deterioration low
Human intrusions and disturbance work and other activities likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium
Invasive & other problematic species, genes & diseases invasive non-native/alien species/diseases - unspecified species happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution agricultural & forestry effluents - nutrient loads happening now some of area/population (10-49%) slow but significant deterioration medium

Grassland Secondary grassland  0 0 good (> 90%) good (> 90%) favourable

Mycteria leucocephala Painted Stork 408 408 individuals 100 favourable
Antigone antigone Sarus Crane 301 275 individuals 92 favourable

Whole area of site (>90%) covered by appropriate conservation designation  A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species  Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity  high
