Here are some interesting trivia from the Department of Environment and Natural Resources or DENR, which placed advertisements on several newspapers on June 5, 2009.
DENR claims that in terms of biodiversity resources, the Philippines was 5th in the world in number of plant species; 8th in the world list of endemic plants; 4th in bird endemism; 5th in mammal endemism; and 8th in endemic reptiles. These species include Philippine tarsier, the world's smallest primate; mouse deer, the smallest deer; Pandaka pygmea, the smallest fish; Rafflesia, largest flower; whaleshark, the largest fish, and Philippine eagle, the largest bird.
The Philippines has 52,177 species of which more than half are found nowhere else in the world. Of the 10,000 to 15,000 plant species in the Philippines, more than half are found only in the country. There are 9,000 species of flowering plants in the Philippines. About 558 of the 1,137 terrestrial species are unique to the Philippines.
There are 3,000 tree species in the Philippines, and 77 species of mangroves.
