Liguasan Marsh, also known as Ligawasan Marsh, is a marsh in the Mindanao River basin in the southern island of Mindanao, Philippines.[1]
The marsh covers an area of around 2200sqkm[2] spanning the provinces of Cotabato, Maguindanao and Sultan Kudarat.[3] 300sqkm of this area is reserved for a game refuge and bird sanctuary[2]
At least 92 species of birds, dozens of fish species, six species of reptiles and five species of amphibians are recorded to live in the area. The marshland is the only area in the Philippines where the Comb-crested Jacana can be sighted according to the Haribon Foundation. The place is also one of the few places in the country where there are populations of the Philippine crocodile and the Estuarine crocodile, and in the forested area of the march, the Philippine eagle.[4]
Liguasan Marsh is also noted for its natural gas deposit which is estimated to cover a radius of 300sqkm.[3]
