F. Land Suitability
- Areas suitable for cultivation both agricultural and reforestation is about 18,204.00 hectares. These areas are Agricultural-Alienable and Disposable land and classified forest land (For Agro- & Production Forest). This is about 60% of the total land area of the municipality. Unclassified forest land or timberland also suited for reforestation has an approximate area of 26,183.6292 hectares or 38% of the total land area of Monkayo.
- There are approximately 14,880 hectares of lands are limited pasture. These can be seen in barangays Inambatan, Awao, Mamunga, Macopa, Babag, Haguimitan. This means that 50 hectares of land per barangay be identified for pasture.
- Approximately about 31,584.067 hectares or 45.58% of municipality’s land area are reserved for forest. These areas are classified according to its purpose such as reforestation, production forest and agro-forest, reforestation of Mt. Diwata as mineral land is included in this aspect.

G. Ancestral Domain
- Of the total land area of Monkayo, 39.07 per cent or 27,070.49 hectares were awarded to the unified Mandaya, Manobo, Mangguangan and Dibabawon tribes covering fourteen barangays, namely Awao, Banlag, Baylo, Casoon, Haguimitan, Mt. Diwata, Naboc, Pasian, Rizal, Salvacion, San Isidro, San Jose, Tubo-tubo, and Upper Ulip. Refer to Table 3.
- It was apportioned into two parcels as shown in Figure 5. The ancestral domain areas of Monkayo also shares common boundaries with four (4) other ancestral domains, aside from the Dibabawon and Mangguangan CADT. Being a melting pot of the four tribes, Monkayo indigenous peoples are uniquely situated in that they already have established relationships with these neighboring CADT holders:
- CADT No. R11-BOS-0403-0006: The ancestral domain boundary on the East extends up to the administrative jurisdiction of the Municipality of Boston, Davao Oriental. However, this overlap in administrative jurisdiction does not indicate conflict with the Boston Mandaya Tribe whom CADT No. R11-BOS-0403-0006 was approved on April 3, 2003, as they have their respective management plans.
- CADT No. R11-NEW-0204-019: The common ancestral domain boundary with the Mandaya Tribe of Compostela, Compostela Valley also does not indicate conflict with CADT No. R11-NEW-0204-019 approved on February 17, 2004.
- CADT No. R11-LAA-1005-35: The common ancestral domain boundary with the Dibabawon Tribe of Laak, Compostela Valley and the in the municipalities of Asuncion, Kapalong and San Isidro, does not indicate any conflict with CADT No. R11-LAA-1005-35 approved October 22, 2005.
- CADT No. R13-VER-1108-089: It was approved on November 7, 2008 and issued to the Manobo Tribe of Santa Josefa, Agusan del Sur covers portions of Barangay Awao, Monkayo.

H. Flora and Fauna
- There are still a few species of indigenous plants and wildlife that can still be found within the ancestral domain, except in populated and farmland areas. However, only a few reptiles, mammals, birds and tree species have remained and were observed by local residents. Originally, there were about a hundred species of trees found in the dipterocarp forest in Mt. Diwata mountain ranges. Based on the latest inventory conducted by DENR with the assistance of Datu Mauricio Latiban, only forty-nine (49) known species and three (3) lesser known species of trees were found. However, abaca and other fiberous plants, rattan and native palms are now endangered. These can only be found in some forested areas within the domain.
- Wild animals, particularly land mammals, are trapped in isolated patches of forests in the western section of the ancestral domain. On the eastern corridor section however, land mammals can travel all throughout the mountain range from Mt. Pasian to the Tagub–Kampalili Mountain in Maragusan. Reptiles such as different species of snakes and lizard family are still observable but in reduced number of sightings. Important species of birds include writhed hornbill and blue napped parrot which conservation status is endangered. An unconfirmed report from some indigenous peoples disclose the presence of an unidentified eagle sighted in Bermuda, at the southern boundary of the ancestral domain.
I. Freshwater Resources
- There are existing surface water resources by type and classifications as reflected in Table 4. It shows that such surface water resources can be a great source for Class AA and A public water supply class I and II, particularly in Pasian, Awao and Salvacion. For agriculture, industrial water supply class I and inland water, surface water resource at Macopa can be of beneficial use.
- Agusan River traversing Barangays Babag, Naboc, Mamunga, Poblacion, Baylo, Jaguimitan, San Jose, Rizal and Pasian can be used as Class B, C, and D. While Naboc River traversing Tubo-Tubo, Naboc, Babag, Mamunga connecting Agusan river can also be beneficial for Class B, C and D.

J. Diwalwal Mineral Reservation Area (DMRA)
- On November 25, 2002 President Gloria Macapagal-Arroyo approved Proclamation No. 297, which excluded a certain area from the operations of Proclamation No. 369 series of 1931, and declared 8,100 hectares as mineral reservation and as environmentally-critical area of which 5,839,71 hectares belong to the municipality. Some productive areas in Mt. Diwata are Tinago, Upper Buenas, Busay, Upper Balite, Lower Balite and Paraiso gold vein systems.
- As finalized in the June 23, 2006 Supreme Court Ruling, the State has full control over the mining operations in the Diwalwal Mineral Reservation Area and can pursue full control and supervision of the exploration, development and utilization of the country’s natural mineral resources with two options: (i) through direct undertaking or by entering into co – production, joint venture, or production – sharing agreements; or (ii) by entering into agreement with foreign – owned corporations for large – scale exploration, development and utilization. See Figure 6.
- There are two government-owned and controlled corporations tasked with managing the DMRA, (i) the Natural Resources Development Corporation (NRDC), and (ii) Philippine Mining Development Corporation (PMDC).
