Mount Malindang is a mountain range rising from 600 meters to 2,404 meters above the mean sea level. The range covers 53, 262 hectares of which about 33,000 hectares is still covered with forest vegetation while more than 20,000 hectares is cultivated and inhabited by forest occupants mostly members of the Subanen Tribe. The forest vegetation is composed of highly diverse species of and plants dominated by dipterocarps. It is inhabited by diverse species of fauna including the rare ones such as the Philippine Eagle (Pithecophaga jefferyi), Rofous Hornbill (Buceros hydrocorax), Tarsier (Tarsius philippinensis) and Flying Lemur (Cynocephalus volans).The mountain range was believed to be formed through series of volcanic activities within the historical times but was not well documented. Several indicators of such activities are found in the site. These include six (6) hectare of Crater Lake (Lake Duminagat) and two (2) big sunken areas (more than 20 hectares each) surrounded by high rock walls, cinder cones, dome volcanic plugs, amphitheater structures, extensive distribution of volcanic rocks, carbonized wood found in pyroclastic deposits and two sulfuric hot springs. The entire mountain range is dissected by several canyons, gores and ravines making its terrain very rugged and the forest beautiful scenery. Mt. Malindang Natural Park lies within the Malindang mountain range in Mindanao, straddling the provinces of Misamis Occidental, Zamboanga del Norte and Zamboanga del Sur. It covers over 34,000 hectares. Its highest peak is at 2,402 meters above sea level. The Park’s allure comes from its waterfalls, crater lake and dense virgin forests which host diverse and rare species of flora and fauna. A variety of trees – large, straight trunked evergreens, igem and almaciga grow in the lower parts of its forests while dwarf and crooked stem trees crowd the mossy forest found in the mountains upper parts. The rare and endangered Philippine Eagle, Flying Lemur, Deer, Tarsier, and Hornbills live in the Park. Other significant species found there include mammals such as the Philippine Deer, Wild Pig, Long-tailed Macaque, Palm Civet and Civet Cat. Moreover, the Park is known to be home of six amphibians, three reptiles, 67 birds and 25 mammals which are endemic to the place.
Lake Duminagat is named after the crater lake and its clear waters. It is nested within a dense forest hosting wildlife such as deer, monkeys and wild boars.
