  9. An overview on sustainable forest management in Peninsular Malaysia
    An overview on sustainable forest management in Peninsular Malaysia (pp. 1-9)
    Abd. Rahman Kassim

    Sustainable forest management has been a topical issue of today. It is not only limited to the removal of timber from the forest, but also the entire operation of planning and implementation of harvesting along established guidelines. The paper presents a brief overview of the development of sustainable forest management in Malaysia with special reference to Peninsular Malaysia. Among the topics discussed are the forest policy and legislation, forest management practices in different production forest types, forest management certification and the importance of research support to evaluate and review the current management prescription. As interest about the need to manage...

  10. Making sustainability work for complex forests: towards adaptive forest yield regulation
    Making sustainability work for complex forests: towards adaptive forest yield regulation (pp. 10-22)
    Herry Purnomo, Teddy Rusolono, Muhdin, Tatang Tiryana and Endang Suhendang

    Criteria and indicators (C&I) have been worldwide accepted as a way to conceptualize and measure sustainability of forest management. Various C&I sets or standards were formulated by different organizations and processes such as ITTO, CIFOR, FSC, ATO and Montréal Process. These standards, particularly in the production aspect, underline the sustained forest yield principle and the importance of using permanent sample plot data to regulate forest yield. This principle can only be achieved when the forest yield is regulated according to its dynamics and growth which is unique for each site and unlikely to be completely known. As a result, no...

  11. A brief note on TPTJ (Tebang Pilih dan Tanam Jalur), a modified Indonesia selective cutting system, from experience of PT Sari Bumi Kusuma timber concessionaire
    A brief note on TPTJ (Tebang Pilih dan Tanam Jalur), a modified Indonesia selective cutting system, from experience of PT Sari Bumi Kusuma timber concessionaire (pp. 23-31)
    Gusti Hardiansyah, Tri Hardjanto and Mamat Mulyana

    TPTJ is the selective cutting and strip planting system. This system is a modification of the Indonesia Selective Cutting and Planting System (TPTI), and was put in practice in PT SBK in 1998. The main purpose of TPTJ is to ensure sustainable harvests, and the conservation of rainforest ecosystems.

    The practice was carried out in a logged-over forest (208 300 ha), consisting of 148,939 ha for logging, 10,972 ha for replanting and 48 389 Ha for conservation. In TPTJ, selected trees with diameter > 45 cm were harvested. The width of clearcut strip is 3 m. A 15-22 m block or...

    Indonesian natural tropical forests would not be sustainable under the current silvicultural guidelines – TPTI A simulation study (pp. 32-46)
    Paian Sianturi and Markku Kanninen

    A permanent sample plot (PSP) dataset was enumerated from primary forest in Jambi province, Indonesia. No logging treatment was applied to the plot during the period in which measurements were taken. The dataset including individual tree information, such as tree identity, diameter and position within the plot, was put into the Sustainable Yield Management for Tropical Forests (SYMFOR) computer framework. The model has been calibrated using the Berau PSP dataset (a region in East Kalimantan).

    Prior to the simulation, the Jambi dataset was compared to the Berau dataset in terms of diameter class distribution, the dominant tree species and tree...

    Permanent sample plots (PSP) are an important tool in monitoring forest dynamics and change. In Malinau Research Forest, East Kalimantan, 24 PSPs of 1 ha each were established and all trees with dbh ≥ 20 cm were identified and their diameters were measured in 1998 prior to logging operations and were re-assessed in 2000 and 2004. Two logging systems were implemented during that period: reduced-impact logging (RIL) and conventional logging (CNV). A total of 705 tree species with diameter at breast height (dbh) ≥ 20 cm were recorded from the permanent sample plots, of which 67 (9.5%) were dipterocarp species....

  14. Progress on the studies of growth of logged-over natural forests in Papua New Guinea
    Progress on the studies of growth of logged-over natural forests in Papua New Guinea (pp. 70-86)
    Peki Mex M.

    This is a summation of progress of growth of logged–over natural forests in Papua New Guinea (PNG) since 1992. A total of 126 PSPs (1ha plots) are distributed throughout PNG. A database management system called PERSYST (Permanent Plot System) was developed to analyse and produced a model called PINFORM (PNG/ITTO Natural Forest Model) for predicting the growth and yield of selectively cut natural forests in PNG. A total of 21 cohort species groups cover a range of mean increment and typical diameters for larger trees of the species. These groups represent different growth models. Average annual increment for overall...

  15. The utilization of growth and yield data to support sustainable forest management in Indonesia
    The utilization of growth and yield data to support sustainable forest management in Indonesia (pp. 87-94)
    Rinaldi Imanuddin and Djoko Wahjono

    Illegal logging and wide circulation of wood without legal documents are indicators of the annual decrease in wood product caused by unstable forest planning as determined according to the Annual Allowable Cutting (AAC). Sustainable management of forest resources can be realized if every effort on forest utilization is based on and referred to sustainable forest management planning. One of the key information needed in forest planning is growth and yield data, and this valid data can be obtained if collected through Permanent Sample Plots (PSP) measurement. Basically, there are three things resulted from PSP, namely diameter increment, volume increment and...

  16. Current status of permanent sample plots in Lao PDR
    Current status of permanent sample plots in Lao PDR (pp. 95-98)
    Chanhsamone Phongoudome and Phonesavanh Manivong

    This paper summarizes the present status of PSPs in Lao PDR during the past 10 years after initiating the establishment of permanent sample plots for Lao’s forestry sector. Three main forest types, namely mixed deciduous forest (MDF), dry dipterocarp forest (DDF) and dry evergreen forest (DEF), with different structure of diameter classes, seedlings, plot topographic features and location and subplot sizes are used to estimate tree growth and to predict yield for future sustainable forest management and planning system (SFMS). However, results of studies from PSPs have not been completed prior to the introduction of forest management systems.

    According to...

  17. The importance of STREK plots in contributing sustainable forest management in Indonesia
    The importance of STREK plots in contributing sustainable forest management in Indonesia (pp. 99-107)
    Sulistyo A. Siran

    Successful implementation of sustainable forest management in the operational level relies on the understanding of the process which occurs in natural forest and the response of the forest due to intervention. Indonesia is fortunate enough to have a vast natural forest in which the forests have been managed for more than three decades, but the knowledge of such process and reaction of the forest (before and after logging) is still very scarce. Through the development of STREK (Silvicultural Techniques for the Regeneration of Logged Over Forest in East Kalimantan) Plot, such knowledge and understanding is expected to improve. These include...

  18. Contribution of permanent sample plots to the sustainable management of tropical forests: what rules to warrant the longterm recovery of timber-logged species? Elements from STREK, Bulungan (Indonesia), Paracou (French Guiana) and Mbaïki (Republic of Central Africa)
    Contribution of permanent sample plots to the sustainable management of tropical forests: what rules to warrant the longterm recovery of timber-logged species? Elements from STREK, Bulungan (Indonesia), Paracou (French Guiana) and Mbaïki (Republic of Central Africa) (pp. 108-109)
    Sylvie Gourlet-Fleury and Plinio Sist

    From 1977 to 1989, the Forestry Department of CIRAD has contributed to the settlement of several large PSPs in tropical regions worldwide, in collaboration with national forest services and/or agronomic research institutes: Mopri/Téné/Irobo in Ivory Coast, Mbaïki in Republic of Central Africa (RCA), Paracou in French Guiana, ZF2 in Brazil, Ngouha II in Congo-Brazzaville, Oyan in Gabon, STREK and Bulungan in Indonesia. The detailed objectives varied according to the particular situations encountered, but the most important, common to all sites, was to assess the impact of logging and possibly complementary silvicultural treatments on the dynamics of commercial species. With increasing...

    Permanent sample plots in damar and rubber agroforests of Sumatra and use of the data for the spatially explicit individual based forest simulator (SExI-FS) (pp. 110-110)
    Degi Harja, Gregoir Vincent and Laxman Joshi

    With the loss of natural forest in Sumatra, the farmer planted and managed agroforests are gaining in importance as source of timber, in additional to their role as supplier of resins, latex and fruit. Long term sample plots have been established in the Damar agroforests of Krui (West Lampung) and the rubber agroforest of Muara Bungo (Jambi). Design of the plots follows the principles of long term forest sample plots. The design of the associated data base included options for parameterization and calibration of the SExI-FS model of growth in mixed tree stands. After calibration the model can be used...

  20. The importance of permanent sample plot network for climate change projects
    The importance of permanent sample plot network for climate change projects (pp. 111-111)
    Daniel Murdiyarso

    Permanent Sample Plot (PSP) has been to some extent standardized in order to ease data and information sharing among developers and users. The community has traditionally been networked for silvicultural and wider forest management purposes. Even if there are differences in terms of format and components reported, there are substantial commonalities and rooms for improvement as far as data exchanges are concerned.

    There has been an increasing demand for data and information collected from PSP for accounting purposes in carbon sequestration projects under climate change agreements. Such information would support the development of the so-called baseline and additionality scenarios presented...
