Calauit Island. This island in Palawan is home to the biggest game preserve and wildlife sanctuary in the Philippines. Initially, 104 giraffes, impalas, topis, gazelles, elands and zebras were imported from Kenya, Africa. They now number well over 600. The forests, grasslands and mangrove swamps also host some of the country's rarest and most endangered species, such as the Calamian deer, bearcat, Philippine mousedeer, tarsier, pheasant peacock, scaly ant-eater and monitor lizard. Calauit's marine sanctuary provides refuge to sea turtles (pawikan), giant clams and the rare seacow (dugong).
