Diani / Shimoni
Kenya · East Africa
Kenya's southern coast hides one of East Africa's most biodiverse marine parks in Kisite-Mpunguti, where whale sharks patrol October to February and humpback whales sing through the channel from June to September, all above pristine hard coral gardens that see a fraction of the tourist pressure of the north.
How this reef is doing
ⓘ How we measure thisReef state
Inside the fully protected park off Shimoni, reef fish biomass runs far higher than in the fished waters around it, from roughly 680 to 1,350 kilograms per hectare against 260 to 460 outside (McClanahan et al. 2006); the wider Diani reef sits outside that boundary.
