The Aliwagwag Protected Landscape is a protected area that preserves a major drainage catchment in the southern Philippine island of Mindanao in the Davao Region. It contains the headwaters of the Cateel River in the southern Diuata Mountain Range which provides the water source and irrigation for surrounding rice fields and communities in Davao Oriental and Compostela Valley provinces. It was named after the remote rural village in the municipality of Cateel where Aliwagwag Falls, the country's highest waterfall, is located.〔(【引用サイトリンク】title=The Highest Waterfall in the Philippines )〕 The protected landscape is part of the Philippines' National Integrated Protected Areas System and was established in 2011 through Proclamation No. 139 issued by President Benigno Aquino III.〔(【引用サイトリンク】title=Proclamation No. 139, s. 2011 )〕 It was initially a component of the Agusan–Davao–Surigao Forest Reserve declared in 1931 through Proclamation No. 369 by Governor-General Dwight F. Davis which underwent several amendments over the years to open up a few areas in the mineral rich watershed to mining.〔(【引用サイトリンク】title=Administrative Order No. 66 )〕〔(【引用サイトリンク】title=Proclamation No. 583, s. 1959 )〕 ==Description== Aliwagwag is situated in the Eastern Mindanao Biodiversity Corridor which contains one of the largest remaining blocks of tropical lowland rainforest in the Philippines.〔(【引用サイトリンク】title=Eastern Mindanao Biodiversity Corridor )〕 It covers an area of and a buffer zone of in the hydrologically rich mountainous interior of the municipalities of Cateel and Boston in Davao Oriental as well as a portion of the municipality of Compostela in Compostela Valley.〔 A tributary of the Cateel River which includes the Aliwagwag Falls flows through the park from the high Mount Agtuuganon in the Diuata Range or Mindanao Pacific Cordillera.

A small Mandaya community who practice slash-and-burn agriculture and plantation farming can also be found in the park's lower slopes.〔(【引用サイトリンク】title=PH087 Mount Agtuuganon and Mount Pasian )〕 Near the park's eastern edge are irrigation canals leading to the Cateel Dam in the village of Aragon which provides irrigation to over of rice fields in 11 villages in Cateel.
