The site was identified as important in 2001 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:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Shoebill Balaeniceps rex	VU	resident	-	present	A1
Papyrus Gonolek Laniarius mufumbiri	NT	resident	1998	present	A1, A3
Carruthers's Cisticola Cisticola carruthersi	LC	resident	1998	present	A3
White-winged Swamp-warbler Bradypterus carpalis	LC	resident	1998	present	A3
Black-lored Babbler Turdoides sharpei	LC	resident	1998	present	A3
Red-chested Sunbird Cinnyris erythrocercus	LC	resident	1998	present	A3
Northern Brown-throated Weaver Ploceus castanops	LC	resident	1998	present	A3
Papyrus Canary Crithagra koliensis	LC	resident	1998	present	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2012) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	good (> 90%)	good (> 90%)	favourable
Wetlands (inland)	good (> 90%)	good (> 90%)	favourable

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%)	no or imperceptible deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Natural system modifications	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Biological resource use	happening now	small area/few individuals (<10%)	no or imperceptible 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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Very little or no conservation action taking place	low

Year	Protected Area	Designation	% overlap with IBA
1932	Mujuzi	Forest Reserve	1
1932	Manwa	Forest Reserve	<1
1963	Kisasa	Forest Reserve	1
2004	Lake Nabugabo wetland system	Ramsar Site, Wetland of International Importance	98
