INTRODUCTION
On June 17, 1986, Municipal Resolution No. 60-86 was passed by the
Municipal Council of Cabadbaran, Agusan del Norte duly approved by its
Mayor Designate Abelardo M.
Carloto thru the proposal of the
National Irrigation Administration
to conserve the forested areas
surrounding the source of
Cabadbaran River for protection
against further denudation and for
extensive reforestation thru
proclamation of 17,900.00
hectares as Watershed and Forest
Reservation Area.
On November 13, 1991, Cabadbaran River Watershed Forest Reserve
was proclaimed by virtue of Proclamation No. 834 signed by then President
Corazon C. Aquino for purposes of protecting and maintaining and improving
its water yield and to provide mechanism
for inappropriate forest exploitation and
disruptive land use containing an area
of 16, 025.00 hectares situated in the
Municipalities of Cabadbaran and
Santiago, Province of Agusan del Norte.
The area was also proclaimed in account
of its importance as main source of
water not only for the previously
mentioned municipalities but also for
the Municipality of R.T. Romulaldez and
portions of Los Angeles, Butuan City.
Since Cabadbaran River Watershed Forest Reserve was already
proclaimed prior to the signing of RA 7586 otherwise known as the National
Integrated Protected Area System Act of 1992 (NIPAS), the area was
considered as an initial component (Section 5 of NIPAS and Rule 6 item 6.1
of DAO 2008-26) dubbed as CABADBARAN-SANTIAGO NATURAL PARK. In
1998, the initial steps for proclamation of the area under NIPAS were done
but unfortunately the 13 steps were not concluded.

In 2009, the created Interim Protected Area Management Board
(PAMB) passed Resolution No. 2009-002 supporting Senate Bill 1066 entitled
“Mt. Hilong-hilong Range Protected Landscape” introduced by Senator Pia S.
Cayetano which covers the Cabadbaran River Watershed Forest Reserve and
Taguibo River Watershed Forest Reserve.
In 2015, Cabadbaran River Watershed Forest Reserve (Cabadbaran-
Santiago Natural Park) was one of the sites targeted for PASA
updating/making use of the old PASA Forums. However, with the issuance
of BMB Technical Bulletin No. 2016-04, an enhanced PASA/ updated PASA
was again conducted to comply the latest guidelines, hence this report.

1. GENERAL INFORMATION
1.1 Geographic Location and Accessibility
The Cabadbaran-Santiago Natural Park (Cabadbaran River Watershed
Forest Reserve per PP 834 S-1991) is geographically and politically under the
Province of Agusan del Norte. It is located in Sitios Ansile, Lusong, Tumipe
and Dagnasay, Putingbato and portions of Barangays Mahaba, Calamba and
Bayabas all of Cabadbaran City and in Barangays San Isidro and Poblacion
1 of the Municipality of Santiago, Agusan del Norte. The area approximately
lies between 9◦10’10” north latitude and 125◦38’00” to 125◦44’30” east
longitude.
The site is 15.6 kilometers from Cabadbaran City proper and is 12.5
kilometers from the junction (Brgy. Comagascas) of the national highway.It
can be reached through riding motorcycles and four-wheel vehicles passing
the road. Portions of the Comagascas-Katugasan Road Section are cemented,
while the Katugasan-Putingbato Road Section is not but expected to be paved
this year through the effort Provincial Government of Agusan del Norte under
the PAMANA Project of the DILG.
1.2 Geographic Features
Protected Area Suitability Assessment 2017
Page | 8
Generally, the area is made up of flat and rolling terrain in which it is
characterized by mountain ranges with uneven distribution of plateau, rivers
& plains. These mountain
ranges are located within the
Barangay’s of Puting-bato,
Mahaba, Del Pilar, Concepcion
& Bayabas of which elevation
ranges from 500 to 1906 meters
above sea level. Surface
stoniness and rock-out crop
were also observed in open
areas.
1.3 Climatic Conditions
The area belongs to the Second climatic type of Corona Classification.
No definite dry season in the place and maximum rainfall occurs from
October to January. The average annual rainfall is 171.29 mm. average
annual temperature is 27.5 degrees.
It is projected that Agusan del Norte may have an average 1.125oC
increase in temperature by 2020 and an average 2.225oC increase in 2050.
The average rainfall will decrease by 7.8 percent during the months of
December to February which supposedly the rainy months of the locality and
5.1 percent increase during September to November by 2020 rainfall
projections. Rainfall projections will continue to increase by 2050 during
December to February and September to November gradually while the drop
of rainfall will be severely experience. This climate scenario may have
significant impact to agriculture, water supply, aquatic resource production,
health, and forestry and might increase the intensity of tropical cyclones as
a result to the temperature rise. Recurring hazard such as floods might be
intense and also incidences of drought might have impact in the locality.
(Source: CLUP of Cabadbaran City).
Historical records show that Cabadbaran City experienced typhoon
yearly that lasts from 1 to 3 days maximum. One of the typhoons that hit
Cabadbaran City was the super typhoon “Nitang” on August 31, 1984 to
September 4, 1984. It brought wide spread damage on infrastructures,
properties, agriculture and even loss of lives’ of Cabadbaranons. In December
2012, typhoon “Pablo” hit the higher portions of Barangay Putingbato

1.4 Vulnerability of Ecosystems & Communities to both Natural &
Man-made disasters
FLOOD
The city experiences
flooding most likely every 1 to 3
years. Extensive heavy rainfall and its continuous downpour
causes overflow of the water from the mountains, rivers and creeks. Though all barangays in
the city are susceptible to flood, barangays within near mouth of Cabadbaran River has the
high tendency of water overflow. All Poblacion
barangays, so with Barangay Cabinet, Concepcion, Comagascas, Puting Bato frequently suffers from moderate flooding. The presence of illegal logging, mining activities, poor
drainage system and the settlers in Cabadbaran were some of the underlying factors contributing to the flood occurrence in the city.
The municipality of Santiago is located on the north-eastern part of
Mindanao Island and falls on the area with a classified type II climate. The
period from December to February is considered the rainy season of the area with high rainfall at 857.7 mm. It is also the period where most of the typhoons may affect the area. It has been observed and recorded that the
locality experienced heavy flooding last 2000, 2002 to 2004 and 2011. It is also observed that the intensity and magnitude of flooding has increased
recently. The Aciga River where water from Lake Mainit outfall swelled during December to February due to waters accumulated from the watershed surrounding the Lake. As a result, Aciga River swelled its banks and flooded
nearby areas damaging crops and properties.
LANDSLIDE
Figure 3- Geo-hazard Map
Protected Area Suitability Assessment 2017
Page | 11
The landslide occurrence in the city was due to the earthquake-induced and rain induced landslide. Barangays Concepcion, Del Pilar, Puting Bato, Calamba and Mahaba have high susceptibility for earthquake-
induced landslide. It usually occurs every 10 to 30 years.
Being situated on and/or near slopes, six (6) barangays in the city have the potential for landslide occurrence. Barangays of Concepcion, Mahaba, and Puting Bato has moderate landslide susceptibility while Barangay Del
Pilar, Calamba, and Bayabas are least susceptible.
Steep slope, denuded forest, loose soil structures are considered some
of the underlying factors in the occurrence of landslide in the city.
So far, the City Disaster Risk Reduction Management Council has no record for the past landslide events affecting the City of Cabadbaran. Minimal occurrences happened but still manageable at the barangay level
and no casualties or damages reported.
The geo-physical condition of Santiago is mostly mountainous on the far west and eastern part. All barangays are prone to moderate landslide. There are no settlements yet in areas identified with high susceptibility to
landslide. Landslide occurs during the rainy months from December to February.
TYPHOON
Cabadbaran City experienced typhoon yearly that lasts from 1 to 3 days maximum. Water overflow from the riverbanks, landslide and liquefaction usually resulted from such occurrences.
In August 31, 1984 to September 4, 1984, super typhoon “Nitang”
brought wide spread damage to the then municipality of Cabadbaran. A total of 21 barangays were severely affected with a total of 61,000 persons. The death toll reached a total of 15, injured persons to 30, missing to 7 and
displaced to 42,700 persons. Houses that were totally damaged reached 300 in number, 34 houses partially damaged and 266 houses were underwater. Personal properties (such as TV, radio, furniture, etc.) were damaged
amounting to P5.5M. As to livelihood and agricultural products damages, it reached to P10 M.
SOIL EROSION
Protected Area Suitability Assessment 2017
Page | 12
Heavy rainfall in Cabadbaran City causes soil erosion especially in places located at high areas such as Barangay Bayabas, Calamba, and Del Pilar which have low susceptibility while Barangays Concepcion, Puting
Bato, Mahaba are moderately at risk of soil erosion and it usually occurs in every 1to 3 years.
EARTHQUAKE
In the City of Cabadbaran, earthquakes are usually caused by rupture of geological faults and landslides. This occurs every 1 to 3 years.
Two fault lines are traversing 10 rural barangays of the city that passes through Barangay Concepcion, Del Pilar, Bayabas, Calamba, Sanghan,
Antonio Luna, Bay- ang, Katugasan, Comagascas, and eastern part of Barangay Mabini. No previous damages as to lives and properties noted in relation to earthquake occurrences in the city.
Municipality of Santiago has nine (9) barangays which are susceptible
to earthquake in moderate impact considering no tall structures are built in except for government facilities with a maximum of three (3) storeys. Santiago fault line is locatedon the center of Poblacion proper and Barangay
Lapaz to Barangay Curva crossing Maharlika Highway at Barangay Jagupit. So far, only three (3) houses were damaged by the presence of this fault. There are no records yet of a damaging earthquake in the locality. The
Santiago fault line is located outside the PA periphecy.
LIQUEFACTION
Based on the data, Barangay Antonio Luna, Bayabas, Calamba,
Comagascas, Concepcion, Del Pilar, Katugasan, Puting Bato, Mahaba, Sanghan and Soriano are the concerned places being high risk of such
hazard. Liquefaction in these places transpires every 1 to 3 years. Like earthquake, no previous experiences as to damages for this type
of hazard reported. For LGU- Santiago only portion of barangays, particularly near Aciga
River, are prone to liquefaction. There had been no incidence reported regarding the impact of earthquake that resulted to liquefaction in the area.
Important considerations must be undertaken in the area for future development in order to limit the impact of the hazard.
TSUNAMI
Protected Area Suitability Assessment 2017
Page | 13
Though tsunami has never happened to the city of Cabadbaran, which the people will not happen like, ever. Still it is considered as one of the possible hazards that will occur more likely from 200 to 300 years especially
in the coastal areas like, Barangay Caasinan, Cabinet, Kauswagan, Calibunan, La Union and Tolosa.
The City haven’t been struck by it but based on research; this
prevalence may cause damage by two mechanisms: the smashing force of a
wall of water travelling at a high speed, and the destructive power of a large volume of water draining off the land and carrying all with it, even if the wave did not look large.
To summarize, the following table shows the results of the survey of
the hazards affecting the City of Cabadbaran by the Mines and Geo-sciences Bureau (MGB).

Dipterocarp species are growing
while in logged-over areas,
brushes, cogons and grasses
(Agsam) are found to be
dominating. A resettlement area
is located in Sitio Lusong. In
lower elevations, particularly in
Sitios Dagnasay and Tumipe, most
of the area is cultivated and planted with agricultural crops, Falcata,
Gmelina and other fast-growing species. Other areas of SitioTumipe and
Dagnasay are planted with indigenous tree species under the National

1.6 ECONOMIC PROFILE
The major sources of livelihood of the people living within and adjacent
in the Protected Area are farming, fishing, livestock & poultry raising, agriculture, quarrying and small scale mining. Majority of the upland
population depends on abaca, falcata plantation and farming as their primary source of income. There are also women’s activity existing in the area such as the Putingbato Community Multipurpose Cooperative and
Modified Conditional Cash Transfer for IP which includes gardening and Family Development System (FDS). In Barangay Mahaba, women are fond of
making baskets, bags, caps and slippers through abaca but due to financial problem, products are made to order.

2. BIO-PHYSICAL FEATURES
2.1 Geological Features
The dominant parent material of the area is developed from metamorphic
rocks. The area is not within the high angle fault line but under thrust fault
and dashed inferred fault (based on the Cabadbaran River Watershed Forest
Reserve Basic Profile). Two fault lines that traverses the 10 rural barangays

Cabadbaran-Santiago Natural Park is made up of several perennial
and intermittent creeks and rivers draining to Cabadbaran River and Narog
River, which is flowing and discharging water to Butuan Bay. The drainage
pattern is radial type.
Cabadbaran River is estimated to have a total length of 35 kilometers
and estimated width from 50-300 meters. Hereunder are the tributaries of
Cabadbaran River:

Most of the creeks and rivers were utilized for irrigation and domestic
purposes.
Groundwater resources are available in almost all barangays covered
by the watershed area in which majority of the artesian wells (deep well) is
free from flowing well. Upland barangays such as Bayabas, Puting-Bato,
Mahaba, Calamba are utilizing spring water, develop into Level II System or
Communal faucet and Level III System or individual house connections to

artesian well formation under its riverbed, which continually produces water
to the river surface.

2.3 Vegetative Cover, ecosystems and habitat types
The Cabadbaran-Santiago Natural Park is covered by various kind of
vegetation found in the upland and lowland areas such as forest and fruit
trees, brushes, shrubs, grasses and herbs, vine and agricultural crops.
The remaining naturally grown
forest cover is located within the
upper most portions of
Cabadbaran-Santiago Natural
Park which is located in Brgys.
Mahaba, and PutingBato. Wild
pigs, deer, bats and several species
of birds, insects and snakes are
still abundant in remote and steep
mountain forest.
There are also several sightings of
“Philippine Eagle” in the higher elevation areas at Barangay Mahaba. In
terms of vegetation, the remaining natural forest still houses the famous
species of dipterocarps (i.e., white and red lauan, dao, yakal) and the now
endangered pitcher plant (Nepenthes species). Orchids, ferns and vines

likewise dominate the forest.Lower elevations of the area are vegetated with
brushes/cogons and grasses (Agsam)
2.5 IMPORTANT FLORA AND FAUNA
A. Flora
Previous records show that forest tree species are mostly found on the
upland and mountainous areas of the eastern side of the protected area.
During the inventory and establishment of transect route, reforestation and
plantation tree species are observed in the lower portions, along roads, and
in DENR established reforestation projects. Rattan species are also found in
the residual forests.

Gathering the aforementioned faunal species for food or trade or to be
used as pet may contribute to their declining population and in turn
escalates their risk to extinction and decreases biodiversity over time.
2.6 IMPORTANT FEEDING, NESTING, REST AREA AND OR
BREEDING SITES OF ANIMALS
There was an unverified report by the
local residents on the presence of Philippine
Eagle (Pithecophaga jefferyi) in Mt. Hilong-
hilong, Mahaba, Cabadbaran City, which is
a critically endangered faunal species in the
watershed area. Balinsasayaw Nest

However last April 8-10, 2016, the
team from the LGU-Cabadbaran facilitated
an activity called “Freedom Climb” at Mt.
Hilong-Hilong. During the said activity, four
(4) from the participants, were able to
witness the Philippine Eagle soaring, but
unfortunately they were not able to capture
the said moments due to the vast fogs that
suddenly covered the site. Accordingly, the estimated height of the said
Philippine Eagle is 4-5 ft. (BARANAS)
3.0 SOCIO-CULTURAL FEATURES
3.1 Cultural Group
More or less 19,336 hectares was awarded to the Manobo-Mamanwa
Tribal communities under CADT R13-CAB-1108-092, represented by
Hawodon Ambongan Lito Manlubatan These cover five (5) barangays, namely
Concepcion, Del Pilar, Bayabas, PutingBato and Mahaba.
Portion of CADT 092 is also the proclaimed Cabadbaran River
Watershed Forest Reserve under Presidential Proclamation No. 834 dated
November 13, 1991. Sitio Lusong is primarily inhabited by Mamanwas.
Cabadbaran City and Santiago was inhabited by the natives mainly of
Manobo and Mamanwa tribes. However, there is no available data as to their
exact numbers at present considering that intermarriages with the migrants
had taken place through the years.
3.2 Description of cultural practices, beliefs and traditions with
emphasis on the use of natural resources
During the early days the Indigenous Peoples (IPs) have a belief
system. They believe that the forest and caves is a home of the Spirits or
Diwata, they also believe in the ritual of thanksgiving. There are ritual
ceremonies done in creeks, cave, forest, animals and fishing for them to have
abundance or good harvest.
BAT
Protected Area Suitability Assessment 2017

The Mamanwa are nomadic in nature, relying on hunting and
gathering to survive and grow minimal crops such as yams to supplement
their foraging activities. The Manobo’s subsistence pattern is, on the other
hand, semi-nomadic relying mainly on shifting agriculture with hunting and
gathering as supplementary activities. Some communities retained these
traditional livelihood activities, but now that they are settled in more compact
and permanent settlements both in town centers and in the uplands, the
Mamanwa and Manobo have also diversified to other economic practices
such as entrepreneurship and the provision of physical labor and other
services. In general though, agriculture remains the primary source of
employment, followed by forestry and inland fishing. For the Mamanwa-
Manobo, all resources within the Ancestral Domain are gifts from
“Magababaya”. As much as they are entitled to benefit from the gifts they are
also requires protecting and conserving it for their future generations.
3.3 Existing land-use patterns within or adjacent to the proposed
protected area
There are mineral-related
uses adjacent to the protected
area such as MPSA area (SEMCO
Mining in Bayabas) and small-
scale mining area (Sitio Agutayan,
Mahaba) and agricultural
developments.
4.0 Social Services
Health
The City of Cabadbaran has its own District Hospital while the
Municipality of Santiago is served only by a Municipal Health Center.
Barangay Health Centers are also present in the barangays covering the
Protected Area and are manned by Barangay Health Workers. The assigned
Nurses of Nurse Development Project (NDP) of Department of Health visits
Figure 7- Tenement Map

the Health Center every Tuesdays, Thursdays and Fridays of every week in
order to check the health issues of people living in the area as well as conduct
pre-natal to pregnant women and immunization to children below 5 years
old. However, emergency and fatal cases were brought to Butuan City where
advanced medical facilities are present. Private health clinics and drugstores
are also present in the the City proper.
The City of Cabadbaran is equipped with both government-owned and
private health facilities. It has three (3) hospitals, two of which are privately
owned. The provincial government administered Cabadbaran District
Hospital, with a twenty-five-bed capacity, is located at Barangay Tolosa of
this City. The two private hospitals are the ten-bed capacity St. Anne Clinic
at Barangay 4, and the twenty-five bed capacity Duay Hospital situated at
Barangay Tolosa. The place is also served by the City Health Office (CHO)
and Barangay Health Stations. The CHO is purposefully established to cater
the needs of the twelve (12) urban barangays. However, people from the rural
barangays can still avail of the health services from the CHO most especially
those which are not offered by their Barangay Health Station. These include
BMONC, Birthing Clinic, and laboratory services like X-ray test, urinalysis,
blood test and the like.
Meanwhile, the Barangay Health Stations are geographically dispersed
to the nineteen (19) Rural Barangays with an assigned midwife to ensure
that quality health services are given accordingly. Cabadbaran also has a
Sagip- Isip Halfway Home, administered by the City Health Office, which
houses & rehabilitates people with mental abnormality.
BARANGAY BIRTHING CLINIC BARANGAY HEALTH CENTER
Protected Area Suitability Assessment 2017
Page | 36
Other than government- run facilities, Cabadbaran City is also served
by seven (7) medical clinics and five (5) dental clinics which are operated by
the private sector. (CLUP-Cabadbaran City 2013-2023).
In terms of health facilities, the Municipality of Santiago has seven (7) Barangay Health Stations and one (1) Municipal Health Office. Barangay
Health Stations provides the first level health services while Rural Health Unit is responsible for the delivery of basic health services and the implementation of various health programs. The Municipal Health Office

permanent vacancy. The seven (7) Rural Health Midwives are assigned to nine (9) Barangay Health Stations. One midwife will have more than one (1) barangay as their catchment area.
Transportation & Communication
Most of the barangays within Cabadbaran are accessible in all types
of land transportation vehicle. However, there are portions in the upland
barangays such as Puting-Bato, Mahaba, Bayabas, Calamba & Bay-ang area
where it can only be reached by riding a motorcycle called “habal-habal”.
Protective Services
Due to inconsistency peace and order, some of the barangays under
the Cabadbaran-Santiago National Park (CSNP) has military detachment as
observed. This helps to lessen the conflicts within the area and to secure the
safety of the community. Each barangays also has a Barangay Police Action
Team (BPAT) to resolve the problem within the barangay level and to
immediately response to any incidents that may be reported within the area.
Provision of peace and order in each Barangays helps to sway more tourists
to stopover and see some of the tourist attractions within the area.
4.0 INSTITUTIONAL FEATURES
4.1 Stakeholder activities or projects within or adjacent to the
protected area
National Greening Program (NGP) is a government priority which aims to
contribute in reducing poverty among upland and lowland poor household,
indigenous peoples and in coastal and urban areas. In line with the
Government’s thrust under E.O. NO. 26, it allows greater and strong
participation of local communities in natural resources management,
environmental protection and conservation efforts and in the same manner
increase the utilization of the local know – how and resources including
Protected Area Suitability Assessment 2017
Page | 37
available and appropriate technologies in the area. NGP develops sense of
ownership and strengthen sustainability of community driven developments
by providing avenues for community participation in project implementation.
Its goal is to plant variety species of trees within forestland, mangrove,
protected areas ancestral domain, civil military reservations, abandoned and
inactive mine sites and other suitable lands.
5.0 ECONOMIC FEATURES
5.1 Distribution of economic activities
Generally, economic activities of the people living within the CSNP
encompasses agriculture and forestry, most of the people in the watershed
have its own farm lot to cultivate while others get their income from small
scale mining and gold panning.
Government development project such as National Greening Program
(NGP) is also one of their sources of income since financial assistance has
been extended to the project beneficiaries.

Cabadbaran-Santiago Natural Park abundantly endowed with water
resources that include rivers, creeks and springs. Cabadbaran River is one
of the principal rivers in Caraga Region. It originates within the the ridges of
Mount Hilong-Hilong & traverses within the municipality of Cabadbaran &
exits at Butuan Bay. Aside from Cabadbaran River, there is also known as
the Narog River. Sumag-a, Saboro Karumi & Tabugsok Falls were among the
falls found in the area located at Brgy. Puting- Bato & Mahaba, Cabadbaran
City. There were also numerous creeks within & adjacent to the protected
area such as the Damasigan, Kalupsayan, Kalasanon, Sigupanon,
