The site was identified as important in 2002 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Green Peafowl Pavo muticus	EN	resident	1998	4-6 individuals	A1, A3
Germain's Peacock-Pheasant Polyplectron germaini	VU	resident	1998	present	A1

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	-	-	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

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 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	medium

Year	Protected Area	Designation	% overlap with IBA
-	Ea So	Nature Reserve	-
1999	Ea so	Khu Bảo tồn thiên nhiên	73

Habitat1	Habitat detail	% of IBA
Forest	Semi-evergreen rain forest (tropical), Moist deciduous forest (tropical)	57
