1. Project description 1.1 Location and size of study area
Administratively, PT. Papua Agro Lestari (PT PAL) is located in Kampung Selil, Ulilin District, Merauke
Regency, Papua Province (6041’30”SL – 7001’00”SL and 140044’30”NL – 140059’30”NL). The
boundaries of PT PAL consist of concession area and natural boundary as follows:
- Northern boundary: Convertible Production Forest (HPK)
- Western boundary: PT. Inocin Abadi
- Southern boundary: PT. Bio Inti Agrindo Blok II
- Eastern Boundary: Fly River
HCS study area of PT PAL is based on Registered Boundary Map of PT PAL Number 011-26.05-2016
dated May 9th, 2016 covering 28,630.46 ha. This area consists of main and plasma plantation, as well
as conservation area.

1.2 Overview of proposed plantation development
The whole area of PT PAL is located in non-forest state area. Land clearing has started at the end of
2015 with a wide area of 358.32 hectares as land preparation for palm oil plantation development.
PT. Papua Agro Lestari has obtained a location permit for palm oil plantation through the Decree of
Merauke Regent No. 8 year 2007 dated January 16th, 2007 on the Granting of Location Permit
covering an area of 39,800 hectares. Then on 14th, April 2007 Decree of Merauke Regent No.
525/1111, was published concerning about Palm Oil Plantation Business Permit (IUP). Afterwards,
this is followed by receiving a Decree of Forestry Minister Number: SK. 552 / Menhut-H / 2012 dated
October 4th, 2012 on releasing of Convertible Production Forest area for palm oil plantation
covering an area of 32,347.40 Ha.

1.3 Description of surrounding landscape
- If low, medium, or high forest cover landscape
Based on the assignment of Papua Province territory through Decree of Forestry Minister number
782 / Menhut-II / 2012, PT PAL area is located in the Other Uses Area (APL). This area is not located
on the Moratorium map (revision 10) which shows the primary forest, conservation and protection
forest, and peat land. Based on the spatial plan (RTRW) map, the area of PT PAL is allocated for
plantation area.

Figure 6. Watershed area in PT. Papua Agro Lestari
Based on the bio-geographical zone of Papua Island, the plantation area of PT. Dongin Prabhawa
enters the ecosystem zone of Southern New Guinea Lowlands Rain Forests or includes the
Southwest Lowland Biogeography. The southwest lowland is a form of the Australian Plates fraction
that is widening from west to east. This area is the largest lowland wet forest ecosystem in Papua.
The endemic species in this zone are the great Cendrawasih (Paradisaea apoda) and mammal species
namely Kangaroo (Macropus sp) with low endemic level. This is because the lowland zone has a wide
type. In addition, very few natural barriers limit the lowland area in the southwest and the Fly-Purari
area in the east.
- Biodiversity features and values
According to the HCV identification report in PT.PAL, 107 animal species were found which consist of
10 species of mammal (8 families), 82 species of bird (31 families), and 15 species of reptile (7
families). According to Red list IUCN 2017, several threatened species in PT. PAL were identified as
vulnerable category. Those species were Rusa timor (Rusa timorensis), Kanguru hutan (Thyloagale
brunii), Kasuari gelambir-ganda (Casuarius casuarius) and Mabruk selatan (Goura scheepmakeri).
Seventy-three species (38 families) of flora were found in the area of PT. PAL. Based on habitus,
vegetation composition at PT PAL concession is classified into 5 (five) classes namely herb, liana,
palm, shrub, and tree. Tree has higher amount of species than other, there are 61 species or 83,59
%. According to Red List IUCN, there were no finding of threatened species, but based on
Government Regulation and Appendix II, there was 1 protected species namely Kantong Semar
(Nepenthes mirabilis).

- History of forest disturbance in the region, drivers of deforestation
PT PAL is surrounded by Production Forest Company, such as PT. Inocin Abadi in the west side and
PT Tunas Timber Lestari in the North side. Based on the Indonesian Law, they cut down trees in
production forest area. This means that deforestation in this area is planned and agreed by the
government.

3. Community engagement/ FPIC 3.1 Summary of community engagement, FPIC, participatory mapping
PT PAL has involved local community to delineate their own land in their process of developing the
palm oil plantation. The result of participatory mapping delivered an agreement over native
customary right land in PT PAL where there were eight (8) tribes inside the area of PT. PAL. This
agreement is also used as basis of land clearing. The details of agreement are as follows:
➢ Mahuze tribe has 1,636 Ha, according to the statement letter of land rights exemption, date
on June 5th 2014;
➢ Maikuin, Koula, Doukuin, Gakuin, and Basikuin tribes have 14,466.4 Ha according to the
statement letter of land rights exemption, date on June 5th 2014.
➢ Mahuze Milafo tribe has 7,466 Ha according to the statement letter of land rights
exemption, date on June 5th 2014;
➢ Kaize dan Basik-Basik tribes have 3,379 Ha according to the statement letter of land rights
exemption, date on June 5th 2014.

Community involvement in the palm oil plantation development of PT. PAL, among others:
1. As a daily worker (nursery, land clearing, survey, etc.)
2. As a local contractor (construction)
The company benefit for community, among others:
1. Compensation for ulayat land,
2. Employment availability,
3. Availability of business opportunity,
4. Various social assistances,
5. Village development fund,
6. Plasma plantation program,
7. Health facility/assistance,
8. Food aid,
9. Educational facility for children around the area.
3.2 Summary of Social Impact Assessment
SEIA assessment was conducted at June 2017. Administratively, PT PAL is located at Selil village, but
the rights holder of ulayat land is marind tribe. The methodology used in the assessment, was using
focus group discussion and interview with each stakeholder and representative of village.
Generally, community perception about the existence of PT PAL in their area is positive. They have
several advantage such as, obtain compensation from their land (Ulayat land), job opportunities,
increase the community welfare, the social program aid, and they can own palm oil plantation by
partnership scheme. There is only small of community that has not received impact from the
company existence.
Positive impacts from the company existence that felt by community as a person or group, such as:
they can work at PT PAL, become the small contractor company for operational activity at PT PAL,
food aid for each tribe, free health facility, educational facility and other social aids. In addition to
the positive impacts, there are also negative impacts such as:
- Reducing hunting and sago area, but usually they have other hunting and sago area.
However, nowadays the consumption level of sago declines. They prefer to consume or buy
rice from the town,
- Potential pollution on the river due to company's operations. To minimize the impact,
company determines the high conservation value on their area and manages it. In addition,
company also conducts water quality test routinely and it is reported to Environmental
Agency.
- The community is not ready to change their life pattern into cultivator, so they can not
follow the company ways of working in high discipline, work target and tight time schedule.

7.4 Methodology used for forest sampling
The sample plot shape was adopted from The HCS Approach Toolkit version 01 as follows:
Figure 13. Sample plot shape for vegetation inventory
Note:
Small plot: 10 m x 10 m: vegetation with diameter at breast height between 5 up to 15 cm
Large plot: vegetation with diameter at breast height more than 15 cm
7.5 Methodology used for carbon calculations
Biomass approach was used to measure carbons stock. Allometric equation from Kettering (2001)
was used to calculate biomass stock based on vegetation diameter and wood density. Wood density
data can be seen on ICRAF wood density data base2. According to HCS Approach document, ratio
between carbon stock and biomass stock is 0.47.
7.6 Indicative photos of each vegetation class
Sample plots of carbon stock measurement were applied in scrub, young regeneration forest, low
density forest, and medium density forest. The figure bellow provides the illustration of sample plot
in scrub, young regeneration forest, low density forest, and medium density forest.

The small diameter trees were not too dominant in this land cover type. This land
cover type had more species than young regeneration forest.
Medium Density
Forest 120.89
The ratio between trees above 15 cm of dbh and less than 15 cm of dbh was 0.57. It
was dominated with trees with diameter >30 cm and climax species, e.g. Vatica
rassak. This land cover type had the same species with medium regeneration forest.

9.2 Comments on Decision Tree outcome
To determine HCS area, we considered several parameters, such as legality, social economy, carbon
stock, and plot analysis. The concession area of PT PAL was designated as plantation based on spatial
plan (RTRW) of Papua Province. The major consideration and important to remember is that this
area designation is for agriculture, based on Indonesian regulation. Local community also supports
the development of their area into palm oil plantation, because this company provides benefits in
form of accessibility, education, and livelihood. In watershed landscape level (Bian and Trans Fly),
66.67% of watershed cover in PT PAL area is covered by forest (766,663 hectares of 1,149,937
hectares). Based on the BAPPENAS report in National Strategy of REDD, the definition of High
Carbon Stock is land cover with carbon stock more than 100 tonC.ha-1, and Low Carbon Stock is land
cover with carbon stock less than 35 tonC.ha-1. Based on the field study data and analysis, average
carbon stock in PT PAL is less than 75 tonC.ha-1 for low density forest and more than 75 tonC.ha-1 for
medium density forest. In this study, land cover with carbon stock more than 75 tonC.ha-1 can be
categorized as High Carbon Stock area based on its density and risk. The HCS area is allocated in the
eastern part of Mandom River with total area of 5,835 hectares.

10. Indicative Land Use Plan 10.1 Summary of results of final ground verification (if any)
Conservation area in PT PAL consists of HCV and HCS area, which include riparian, forest, and the
area around water spring. Regarding to elaboration, PT PAL welcomes other parties to verify the
result of this study.

10.3 Overview of forest conservation management and monitoring activities to be included in
the Conservation and Development (land use) Plan
There are several activities related with management and monitoring plan in HCV document. Here
are activities that should be done in PT PAL:
1. Defining conservation area in the field based on HCV map.
2. Biodiversity and physic monitoring in conservation area.
3. Vegetation enrichment in HCV area by planting, nursing and maintaining periodically trough
monitoring.
4. Security improvement in conservation area.
5. All activities must involve local community or participative
10.4 List of activities still to be carried out before Conservation and Development Plan can be
finalized
1. Dissemination about conservation area, plan, and management along with local community
and government.
2. Making an agreement for collaborative conservation management.
3. Human resources improvement for those who will be involved in managing the conservation
area.
