The site was identified as important in 1999 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
Black-necked Grebe Podiceps nigricollis	LC	non-breeding	1997	3,700 individuals	A4i
Greater Flamingo Phoenicopterus roseus	LC	non-breeding	2001	18,540 individuals	A4i
Lesser Flamingo Phoeniconaias minor	NT	non-breeding	1999	1,070,000 individuals	A1, A4i
A4iii Species group - waterbirds	n/a	non-breeding	-	1,000,000-2,499,999 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1999) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2023) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Climate change and severe weather	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium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
1970	Lake Bogoria	National Reserve	71
2001	Lake Bogoria	Ramsar Site, Wetland of International Importance	71
