With an estimated 13,500 plant species in the country, 3,200 of which are unique to the islands, Philippine rainforests boast an array of flora, including many rare types of orchids and rafflesia. Many species are endangered and scientists say that Southeast Asia, which the Philippines is part of, faces a catastrophic extinction rate of 20% by the end of the 21st century due in part to habitat loss resulting from deforestation.
