We have an update about our 40 hectares reforestation project in Mawas, Central Kalimantan, which is only possible thanks to our wonderful supporters.


The BOS-US and BOS-UK Reforestation Project activities for the period October 2022 to March 2023 include the following:

  • Seedlings preparation and maintenance in plantation nursery
  • Land and planting preparation:
    • Establishing planting line and planting stick installation
    • 40 Ha planting implementation
  • Monitoring and Technical Assistance
  • Fire extinguishing and prevention
    • Firebreak and deep well/hydrant construction
  • Seedlings transport to planting holes

Progress of Project Activities:

Several activities were conducted during September 2023-December 2023 for the BOS-US and BOS UK 40 Ha Reforestation Project including recurring seedlings maintenance in plantation nursery, establishing planting line and seedlings transport to planting hole, coordination meeting between BOSF Mawas and Reforestation Group, implementation of 40 Ha reforestation, establish firebreak, and hydrant construction.

Seedlings Maintenance in Plantation Nursery

Seedlings maintenance in the plantation nursery including regular watering, soil enrichment using organic fertilizer, weeding, and pest and disease protection and prevention. In September 2023, the seedlings show a healthy appearance and compact soil and rooting systems. The average seedlings height in September 2023 was 45-55 cm and in October was 70-80 cm. The seedlings’ acclimation process was completed, and the seedlings were 100% ready to plant. However, due to the seedlings’ longtime storage in the plantation nursery, the roots of the seedlings were penetrating the purun polybag. This condition could affect the seedlings’ condition during the transport process, making them prone to stress.  The documentation of the seedlings’ condition can be seen in Figure 1 & Figure 2, and the number of seedlings of each type can be seen in Table 1.

The establishment of the planting line and planting stick installation have been completely conducted from September 1, 2023, to September 13, 2023. Each group was targeted to establish 76 planting lines in 6.7 ha area each. The documentation of this activity can be seen in Figure 3 below.

40 Ha Reforestation

The implementation of 40 ha BOS US-UK reforestation was delayed from August 2023 to October 2023. The delay of the implementation was caused by dry season and to avoid the risk of fire that might happen inside the plantation area. On October 31, 2023, coordination meeting was conducted between BOSF Mawas and 6 reforestation group representatives (Figure 4) with agenda:

  • Reviewing implementation of the land preparation activity
  • Provide update to the group representative regarding plantation condition and 2nd term payment
  • Preparation of follow up plan

Based on the meeting agreement and considering the weather and plantation condition, the implementation of the 40 Ha planting will be conducted on November 3, 2023, and the activity including seedlings transport from the plantation nursery to the planting hole and the verification of the implementation (requirement for 3rd term payment).

Figure 4 coordination meeting with reforestation group

The implementation of seedlings planting activity has been conducted on November 3, 2023. The planting implementation including seedlings transport from plantation nursery to plantation area and seedlings planting (Figure 5, Figure 6). Total plantation area of 40 ha with 456 planting lines and 44,688 planting sticks, planting holes and seedlings. The seedlings were planted with the planting distance 3 x 3 m. There are 9 types of trees planted (Figure 7, Figure 8, Figure 9) and there are 6 reforestation groups involved in this project. The detailed information of the implementation of 40 Ha BOS US-UK Reforestation Project is presented in the Table 2 and Table 3 below.

Monitoring and Technical Assistance

Monitoring of the plantation area was conducted in December 2023 to observe the plantation and seedlings’ post-planting condition. Due to increasing rain frequency affecting river to overflow to the plantation area, therefore in December 2023, 100% area of BOS USA-UK plantation was flooded and some of the seedlings were submerged. The plantation area condition in December 2023 can be seen on Figure 12.

Figure 12 Increased water level in plantation area, December 2023

Based on the seedlings monitoring, the condition of the seedlings was in the process of adapting to the plantation condition, some of the seedlings experienced post-planting stress and the seedlings that already adapting to the plantation condition were grow well. The seedlings condition in December 2023 can be seen on Figure 13 and Figure 14.

Fire Prevention and Mitigation

The implementation of 40 ha reforestation was delayed due to the condition of the plantation and the presence of forest and land fire surrounding BOS USA-UK 40 Ha plantation area. Since August 2023, there have been several cases of fire in BOSF Mawas working area. The nearest fire incident from BOS USA-UK plantation happens in Compartment M1.

Fire Incidents in the M1 Compartment

On Tuesday, September 26, 2023, a forest fire was reported by Herto and Rahiman during their area monitoring in Danau Telu area near BOS Australia 60 Ha plantation. The fire was located approximately 60 m away from the river bank, the hose that the monitoring team brought was only 40 m long, therefore the fire extinguishing effort was not sufficient. The team reported this fire location and requested a longer hose. When the supporting team (Hengky and Moko) and the hose arrived, the fire had spread 1.5-2 ha due to strong wind that points to 60 Ha plantation area.

10 staff were assigned to extinguish fire and construct a firebreak on Wednesday, September 27, 2023. Several fire points were successfully extinguished; however, the other fire points were continuing to burn away from 60 Ha BOS Australia plantation area into an unreachable area.

On Thursday, September 28, 2023, at 10.00 AM local time, the fire reached to BOS US-UK 40 Ha plantation area, and the total affected area was 19,21 Ha inside and outside the plantation area. All the available staff were divided into 2 teams to construct a firebreak and extinguish fire in the border of BOS US-UK and BOS Australia plantation. At 19.21 Local time, the fire spreads in the southeast direction, approximately 200 m from the border of 40 Ha plantation area, pointing to Mantangai River.

On September 29-30 the fire spread in every direction and the team continued to put all effort into extinguishing the fire as well as protecting the plantation area. 

The documentation of fire incidents and the mitigation in September 2023 can be seen in several figures below.

Fire Break and Deep Well/Hydrant Construction

On October 1, 2023, the fires that spread inside the plantation area were extinguished. Firebreaks were constructed bordering the plantation area 616 m length and 4 m wide (Figure 14). The total burned area in 40 ha plantation area was 28.02 Ha and there are 354 planting lines affected by the fire, leaving 11.98 Ha area and 102 planting lines as seen in Figure 12.

Figure 15 Plantation area condition post-fire incidents

To protect the plantation area from fire, 8 deep well/hydrant were constructed on the side of the plantation area (Figure 15) with 200 m distance from each hydrant. The location of the hydrant is depicted in Figure 13 below. The documentation of deep well construction can be seen in Figure 15.

Since the project started until December 2023, we have received funds amounting to IDR 743.350.094 or around 85% of the total budget in the work plan (Total budget IDR 878.643.600).  Meanwhile, the expenses for implementing activities up to December 2023 are IDR 792.723.598, so there is a funding shortfall of IDR  – 49.373.504, as shown in the table below.
