São Tomé and Príncipe, a two-island nation in the Gulf of Guinea, is known for high levels of species found nowhere else. Its isolation has produced distinctive birds, plants, and reptiles across a small land area.
Príncipe island was designated a UNESCO Biosphere Reserve in 2012. In 2025 the entire country became a single UNESCO Biosphere Reserve, covering volcanic peaks, rainforests, and agricultural land. Obô natural parks protect rainforest on both islands.
Studying the islands’ equatorial ecosystems covers endemism, rainforest ecology, and the balance between conservation and local livelihoods such as fishing and cocoa farming.
