1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2002) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2008) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	-	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation	% overlap with IBA
-	Ban Bung	Nature Reserve	100
1994	Na Hang	Khu Bảo tồn thiên nhiên	71
2004	Nam Xuan Lac	Khu Bảo tồn loài và sinh cảnh	2

Habitat1	Habitat detail	% of IBA
Forest	Semi-evergreen rain forest (tropical), Hill evergreen forest (subtropical)	70
Artificial/Terrestrial		15
Shrubland	Secondary scrub	15
