The Philippines is recognized as one of the world’s most important biodiversity hotspots. Despite covering a relatively small land area, the archipelago contains extraordinary levels of endemic plants and animals found nowhere else on Earth. Many of these species survive within a handful of forests, mountains, wetlands, islands, and marine ecosystems that have become critical conservation priorities.
From the ancient rainforests of the Sierra Madre and the mountains of Mindanao to the coral reefs of Palawan and the Visayas, biodiversity hotspots help protect the wildlife, ecosystems, and natural landscapes that make the Philippines one of Asia’s premier ecotourism destinations.
