Bukidnon is a landlocked
plateau in north-central Mindanao and the only one in Northern Mindanao. It is bounded on the north by
Misamis Oriental and
Cagayan de Oro; on the south by
Cotabato and
Davao City; on the east by
Agusan del Sur and
Davao del Norte; and west by
Lanao del Sur. It lies between parallels 7°25' and 8°38' north latitude and meridians 124°03' and 125°16' east longitude.
Malaybalay, the capital city, is about by air from
Manila and by road from Cagayan de Oro. It has two important landmarks,
Mount Kitanglad and
Pulangi River. Mount Kitanglad has a peak of above sea level. Pulangi River, on the other hand, traverses through the northeastern and southern part of the province towards the
Rio Grande de Mindanao.
Land area The province's total land area is ,10,498.59 making it the largest in Mindanao in terms of land area. It accounts for 59 percent (59%) of
Northern Mindanao. Thirty-eight percent (38%) is classified as alienable and disposable. The rest is timberland forest. It also accounts for 80 percent (80%) or 34 million metric tons of the region's nonmetallic mineral deposits, which include high grade white and red clay, gold, chromite, copper, serpentine, manganese, quartz and limestone deposits can also be found in the province.
Topography . Also located in the town is a canyon near barangay Lunocan, dubbed as the "
Grand Canyon of the Philippines". Much of Bukidnon is an extensive plateau, but the southern and eastern boundaries are mountainous. The province's average elevation is above sea level. The slope gradient peaks at of Mount Kitanglad, an extinct volcano occupying the central portion. Two other mountain bodies are found in its southern portion, Mount Kalatungan and Mount Tangkulan, which rise to and , respectively. The rest of the province is composed of nearly level terraces,
alluvial plains,
canyons and gorges. The volcanic terraces and volcanic foot slopes that are ≥500 m above sea level are estimated to be about . Gently rolling grassland plateau are cut by deep and wide canyons of the
Cagayan,
Pulangi, and
Tagoloan rivers and their tributaries, which cover a greater part of the province. The Bukidnon plateau is mainly of volcanic zone consisting of
pyroclastic,
basaltic and
andesitic cones. of the Maapag Plain of central Bukidnon. The foothills of the
Kalatungan Mountain Range is visible on the upper right. The whole eastern and southern border adjoining the provinces of
Agusan,
Davao del Norte, and
Cotabato are covered by lofty and densely forested
Pantaron Mountain Range, also known as the Central Cordillera. The Central Cordillera is a mountain range of sedimentary, metamorphic and igneous rocks. About 49% of the land resource of the province is of rugged hills and mountains and 33% of undulating to rolling terrain. At Mailag, south of
Malaybalay, the plateau begins to descend and gradually merges into the lowlands of
Cotabato province.
Climate Two types of climate are roughly divided by the northern and southern areas of Bukidnon. The northern part is classified as belonging to Type III, that is, there is no pronounced rain period but relatively dry during the months of November to May. In the southern portion of the province, the climate is classified as Type IV with no dry season. The driest area is Baungon, while the wettest is the Calabugao plain. The climate is relatively cool and humid throughout the year. The average annual rainfall is . Just like in other parts of the country, rainfall is more pronounced from June to October compared to other months of the year. February to April are the drier months. Temperature ranges vary with elevation. In areas lower than above sea level (m.a.s.l.), the recorded temperature range is between . Areas with elevations greater than above sea level would have temperatures ranging from . Relative humidity also varies with elevation, with those above 500 m having relative humidity of about 80%, while areas lying below , 65-7 percent. Thus, the Malaybalay-Impasugong area and those around the volcanic cones approximate semi-temperate conditions and can support the cultivation of highland tropical crops. Based on the records of climatological stations within and near the province,
lithology and land form, three agro-ecological zones are identified. One covers the mountainous eastern side (Central Cordillera), which is generally wet, with rainfall of about per annum. Another covers the high altitude volcanic plains, the Malaybalay-Impasug-ong area, and the foot slopes of Mount Kitanglad, and Mount Kalatungan. These areas have an annual rainfall in the range of . The third zone covers the south-central and the north-western parts of the province, with elevations of less than 500 meters, relatively dry with mean annual rainfall in the range of .
Bodies of water Rivers Bukidnon is home to the largest concentration of watersheds in Mindanao. It is endowed with six major river systems, namely: Pulangi, Tagoloan, Cagayan, Manupali, Muleta, and Bobonawan rivers. These rivers and their tributaries carved the landscape of the province, creating numerous canyons into the plateau. The
Pulangi River, considered the longest river in the province, is a tributary of the
Rio Grande de Mindanao. Its headwaters are found in the mountains of Kalabugao,
Impasugong. It is the largest as well as the longest river found in the province. It covers the following cities and municipalities of the province:
Impasugong,
Malaybalay,
Cabanglasan,
San Fernando,
Valencia,
Maramag,
Quezon,
Don Carlos,
Kitaotao,
Dangcagan,
Kibawe and
Damulog. The
Tagoloan River has its headwaters in the mountains of Can-ayan, Malaybalay. It traverses the province northwestward passing through Malaybalay, Impasugong, Sumilao, Manolo Fortich, Malitbog and finally empties into the sea at
Tagoloan, Misamis Oriental. winding through the Maapag Plain in
Valencia City The
Cagayan River watershed is found mostly in the municipality of Talakag. Its headwaters are found in the Kitanglad Mountain Range in central Bukidnon. The river flows northward through the municipalities of
Talakag and
Baungon. Its mouth lies at
Cagayan de Oro in
Misamis Oriental, where it is the main source of potable water. The
Manupali River, a major tributary of the Pulangi River, starts in the mountains of
Lantapan, Bukidnon, picking up tributaries along the way from the Kalatungan and Kitanglad Mountain Ranges. It forms part of the natural boundary of the
Valencia and
Lantapan. It flows eastward towards
Malaybalay, eventually joining the Pulangi River in Valencia. The
Muleta River is found in the southern portion of the province covering the municipalities of
Pangantucan,
Don Carlos,
Kitaotao,
Dangcagan,
Kibawe,
Kadingilan and
Damulog. It is another important tributary of the Pulangi River and flows southward. It will join the Pulangi River in the boundary of Bukidnon and
Cotabato province. The
Bobonawan River, found in the municipality of
Cabanglasan, is another tributary of the Pulangi River. It covers most of the parts of the municipality, flowing southward towards Pulangi River.
Lakes Aside from the relatively important river systems, various lakes also dot the landscape of the province.
Pinamaloy Lake, in
Don Carlos, Bukidnon, is the largest in the province covering about 50 hectares. It was named after Barangay Pinamaloy, where the lake is located. Another lake is found in Pigtauranan,
Pangantucan called the
Napalit Lake. The lake covers an area of 36 hectares and is one of the tourist spots in Pangantucan, Bukidnon. There are 24 floating islets in the lake. The third significant inland body of water in the province is
Apo Lake at Guinoyoran,
Valencia. It occupies an approximate area of 25 hectares. A man-made lake called
Pulangi Lake or Maramag Lake is found in
Maramag, Bukidnon, which was the result of the construction of the
Pulangi IV Hydroelectric Dam of the
National Power Corporation (NPC) in the course of the Pulangi River.
Springs and waterfalls There are also numerous springs and waterfalls located in the province. Some of the waterfalls include the Alalum Falls, Dimadungawan Falls, Dila Falls, Gantungan Falls, Natigbasan Falls, Sagumata Falls, Magubo Falls, and Balisbisan Falls. == Biodiversity ==
