Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	poor (40–69%)	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (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 (management category)	% coverage of IBA
1949	Omo	Strict Nature Reserve (Ia)	<1
1977	Omo Strict Natural Reserve	UNESCO-MAB Biosphere Reserve (UA)	99
