Encompassing some 2,700 square kilometers, Mau Forest is considered the most important water catchment in western Kenya, providing water to millions of people. But recent satellite data reveal that Mau is continuing to lose its water-giving forest cover. Most of Mau Forest is encompassed by a complex of around a dozen protected areas. However, despite formal protections, Mau lost around 25% of its tree cover due to human pressure between 1984 and 2020, according to forest monitoring groups. Satellite data from Global Forest Watch show forest loss dropped dramatically in 2021 and 2022 before shooting back up in 2023. Preliminary GFW data and imagery indicate the Mau Forest has been experiencing another major bout of deforestation in 2024.
