Weather…

The Nioumbadjou Forest stretches across the slopes of Mount Karthala on Grande Comore island and represents one of the last contiguous primary forest areas in the archipelago. This ecosystem is of critical importance for the preservation of Comorian biodiversity, as it shelters numerous rare and endemic species. The forest is particularly renowned for the presence of the Comoro Scops-owl and the Karthala White-eye, which can only survive within this specific habitat. The vegetation consists of a mix of tropical rainforest and montane forest, where giant tree ferns and moss-covered trunks define the landscape. Due to high precipitation rates on the volcanic slopes, the forest functions as a vital water catchment area that feeds the island's aquifers. In the past, the area was threatened by deforestation and the expansion of agriculture, leading to intensified conservation efforts. Today, the Nioumbadjou Forest is a focus for scientific studies on island biogeography. The preservation of this forest ecosystem is central not only for wildlife but also for climate protection in the Comoros. Hiking trails through the forest offer nature-loving visitors the chance to experience the unique flora and fauna firsthand.
