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.

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.
