Nous avons constaté une forte corrélation entre les abondances de flamants nains et de chlorophylle- a. Ce site est connu pour accueillir des milliers d'oiseaux tout au long de l'année. Le lac Natron est le seul site de reproduction régulier de la population est-africaine de cette espèce spécialisée. Cette étude, menée dans trois lagunes du lac Natron pendant dix mois consécutifs à compter de mars 2019, a examiné la relation entre les abondances de chlorophylle- a et de flamants nains, ainsi qu’entre les variables physiques et/ou chimiques et l'abondance de la chlorophylle- a. Le flamant nain, qui est un animal filtreur de phytoplancton, est largement considéré comme étant l'espèce emblématique de ces terres humides salines et alcalines sur tout le continent africain. Les lacs salés sont des écosystèmes alcalins caractérisés par des conditions extrêmes et sont l'un des écosystèmes aquatiques les plus productifs. Thus, the conservation and management of this lake require concerted efforts from different stakeholders including those found in Kenya. In turn, these changes are mainly due to both anthropogenic activities and weather changes within the lake basin and its surroundings. Findings from this study suggest that annual fluctuation in the lesser flamingos numbers in Lake Natron is triggered by phytoplankton abundance whose primary productivity is influenced by physical–chemical variables in the lake waters. Chlorophyll- a abundance was significantly influenced by dissolved oxygen, water turbidity, phosphate, nitrate and ammonium. There was a strong correlation between lesser flamingo and Chlorophyll- a abundances. Lake Natron is the only regular breeding site for the East African population of this specialised species and is known to host thousands of birds year-round. This study, carried out at three lagoons in Lake Natron for ten consecutive months from March 2019, investigated the relationship between Chlorophyll- a and lesser flamingo abundances, and physical–chemical variables and Chlorophyll- a abundance. Lesser flamingo, an obligate phytoplankton filter feeder, is widely identified as the flagship species of these saline-alkaline wetlands throughout the African continent.

Soda lakes are alkaline ecosystems characterised by extreme conditions and are one of the most productive aquatic ecosystems.
