Lake Boundouni is famous as a UNESCO Biosphere wetland in Comoro islands
It is very interesting with its fauna and flora consisting of the endemic waterfowl known as Moheli little grebes.
The Lac Dziani Boundouni is a unique natural feature located on the island of Mohéli in the Comoros. It is a volcanic lake and one of the few freshwater lakes in the Comoros. The lake is part of the Djando region and is surrounded by a small forest rich in biodiversity.
It is classified as a Ramsar site since February 9, 1995, highlighting its ecological significance. The lake supports a diverse bird population, with species like the Greyheaded Sandpiper being particularly notable. The lake's unique characteristics and its status as a Ramsar site make it an important area for conservation efforts and environmental protection
The village of Hamavouna is the nearest to the lake, and villagers use to protect the area as an ecogarde in order to keep the place safer.
Lake Dziani Boudouni is normally a crater lake and one of the few freshwater lakes in the Comoros. Limnological characteristics of the site and upwellings suggest subterranean volcanic phenomena. The ancient lake may have some connection with the ocean. No large animal species are found, but a diverse bird population is supported. Ramsar site
The terrestrial portion of the park has rugged terrain, with deep stream valleys separated by ridges. The highest point is Mont Mlédjélé (790 m). Most of the island was once forested, but most of the forest was cleared for agriculture or livestock raising, or degraded by activities like timber harvesting. A large enclave of relatively intact forest remains on the west and south-facing slopes of Mount Mlédjélé.
The forest is home to the native trees Pterophylla comorensis and Khaya madagascariensis, which are valued for their timber, and many other species of trees, shrubs, ferns, and orchids, including many Comorian endemic species. Native animals include Livingstone's fruit bat (Pteropus livingstonii), which lives only on Mohéli and Anjouan, the Moheli scops owl (Otus moheliensis) and Moheli brush warbler (Nesillas mariae), which are endemic to Mohéli, and other species of birds, reptiles, and insects endemic to the Comoro Islands.
