The site was identified as important in 2003 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2003) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2003. The most recent assessment (2010) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	very poor (< 40%)	very poor (< 40%)	very unfavourable
Wetlands (inland)	very poor (< 40%)	very poor (< 40%)	very unfavourable
Artificial/Terrestrial	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Agricultural expansion and intensification	past (and unlikely to return) and no longer limiting	majority/most of area/population (50-90%)	very rapid to severe deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
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

Year	Protected Area	Designation	% overlap with IBA
1999	Ang Trapeng Thmor	Protected Forest	81

Habitat1	Habitat detail	% of IBA
Artificial/Terrestrial	Rice paddies	50
Artificial/Aquatic & Marine		minor (<10)
Forest	Moist deciduous forest (tropical)	minor (<10)
Wetlands (inland)	Artificial wetlands	minor (<10)
