D A F F  Project

AUS agri for fishTFF has recently completed all activities under an Australian Government, Department of Agriculture, Fisheries and Forestry (DAFF) grant under the Asia Pacific Forestry Skills and Capacity Building Programme (APFSCBP). Funding had been provided in support of the TFF “Forest-Market Linking Program” which involves training in RIL as well as baseline assessments for legality and CoC audits. Together with the RAFT project, the grant from the Australian project has greatly assisted in enabling TFF to deliver on all RIL training requests.

R A F T  Project

RAFTThe Responsible Asia Forestry and Trade (RAFT) program, builds on the successes of the Global Development Alliance, a USAID-sponsored program in Indonesia, and applies lessons learned on a regional scale. RAFT works with forest producers in Indonesia, Malaysia, Vietnam, Cambodia, Laos, and Papua New Guinea. Additionally, RAFT works in other countries such as China, Japan, Singapore, members of the European Union, and the U.S. to address procurement and investment policies that promote the legal timber trade.

IFACS seeks to achieve its goals by working with a variety of government, NGO, and private sector partners in eight landscapes across the country in order to promote and train partners in the adoption of best management practices (BMP). TFF joins the IFACS project in the third year of a four year project with the task of training forest concessions in the adoption of BMP as defined by TFFs RIL Standard. TFF will provide training to eleven natural forest concessions and implement this training program over a three year period.

G I Z Project

GIZ With the Forests and Climate Change Programme (FORCLIME), Germany supports Indonesia's efforts to reduce greenhouse gas emissions from the forestry sector, to conserve forest biodiversity, and to implement sustainable forest management. An agreement between FORECLIME and TFF was signed in 2014, to conduct a comparative study of logging as conventionally carried out in Indonesia and a reduced impact logging (RIL) management regime where the principles and practices of reduced impact logging have been applied. The study sought to influence practices in the RIL study area in order to evaluate key metrics such as machine productivity, soil disturbance, utilization of main stem volume, and retention of biomass.

Armstrong World Industries, Inc.

Armstrong Armstrong World Industries, Inc., the world’s largest hardwood flooring company, is partnering with the Tropical Forest Foundation (TFF) to promote responsible forest management practices. Armstrong requires its wood suppliers to adhere to all applicable laws and regulations, including those covering raw materials and labor. Less than five percent of the Company’s wood purchases come from tropical forests. In those instances, Armstrong requires suppliers to produce documentation verifying their adherence to national and international rules and regulations governing specific tropical wood species.

K f W / GFA Project

gfa logo01 One of the goals of ForClime FC is to encourage sustainable forest management within its project areas by developing management models that can be tested and scaled up. In collaboration with PT Sumalindo who are managing a logging concession in Berau, East Kalimantan under long term license. ForClime FC has identified a need to investigate the logging practices of PT Sumalindo Lestari Jaya IV to see if the application of RIL could reduce environmental damage and be more cost effective than conventional logging, thus demonstrating an incentive to implement practices which reduce carbon emissions through better retention of forest biomass.  TFF will implement a study to compare logging as conventionally carried out in Indonesia, to a logging regime where the principles and practices of reduced impact logging have been applied.  The objective of this study will allow the environmental, ecological and cost aspects to be compared as well as setting the stage for a comparison of the potential for reduction of carbon emissions through improved forest management.

PT Erna Djuliawati - A Veteran of Certification in Indonesia

PT Erna Djuliawati has never looked back since that eventful day in 2005 and has moved ahead from strength to strength. Now in its 9th year of certification, the management and staff of PT Erna are confident and proud of their achievement.


The Company
PT Erna Djuliawati is a subsidiary of the Lyman Group.  PT Erna operates a 184,206 ha concession in Central Kalimantan and a plywood factory near Sanggau, West Kalimantan.


Like most Indonesian companies, corporate history has evolved through various mergers and takeovers.  In 1999, the company negotiated a new contract with the Ministry of Forests, which issued a 70 year license based on the adoption of the TPTJ silvicultural system 1).


Market Orientation
The company transports its logs by road to a log pond on the Melawi River, a few kilometers upstream from the town of Nanga Pinoh in West Kalimantan.  From here the logs are transported by river to its industry situated on the Kapuas River near the town of Sanggau.


PT Erna operates a modern and efficient plywood factory which features 9 peeler lines and a fancy veneer section.  Apart from the wide range of plywood sizes, PT Erna has developed a reputation as a manufacturer of high quality container flooring.  Its fancy veneer line feeds into a sizeable  production of engineered flooring products which are finished off in its subsidiary mill in Tangerang on the Island of Java.


Social Context
Access to the concession is from West Kalimantan, however, traditionally access has been along the major rivers draining the concession to the East. Indigenous Dayak peoples have long since converted the area along these rivers to shifting cultivation.


The concession is home to 14 villages.  Almost 4,000 people live within the concession boundary and engage in subsistence agriculture, a land use practice which is fundamentally at odds with the practice of sustainable forest management.


Good community relations, is one of the company’s strengths.  The company has a full time doctor on staff and provides free medical services as well as transportation to the local communities within the concession.  Community awareness of the company’s health care facilities is very high and access and use of these facilities is free to the community.


The backbone of the company’s community relations is its PMDH program2).   The program includes joint demarcation of areas considered by the villages as belonging to them under a system referred to as PGM3) or, community land use areas.  In addition, the company actively solicits input for local communities regarding culturally significant sites and then protects those sites from logging and demarcates them both in the field and on its maps.


PT Erna has established primary schools in 6 villages and supports 13 teachers.  At its base camp, some 50% of the students come from local communities in the concession.  In addition, the company provides over 20 university scholarships per year for advanced studies in Palangkaraya or Pontianak.


One of the areas where PT Erna has truly excelled is in the development of its management systems.   However, insisting on quality systems costs money, hence optimizing efficiency had to become a major consideration.  As a result, the concept of reduced impact logging (RIL) was quickly recognized as having the potential to contribute to increased efficiency while at the same time enhancing environmental performance.


  1. PT Erna implements a modified version of the TPTJ system (Tebang Pilih tanaman Jalur), or Selective Cutting and Line Planting System
  2. The PMDH (Pembinaan Masyarakat Desa Hutan) or Forest Village Development Program is run by the Community Assistance Department and employs approximately 50 staff.
  3. PGM (Pemukiman dan Garapan Masyarakat) is a land demarcation recognized at the District level of government.
