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 ...

Pembalakan ramah lingkungan: Manfaat dan hambatan
Reduced-impact logging (RIL) and conventional techniques (CNV) were compared in a mixed dipterocarp hill forest in East Kalimantan in three blocks of about 100 ha each. Damage was evaluated using pre- and post-harvesting assessments in 24 one-hectare sample plots. RIL techniques nearly halved the...

Reduced-impact logging in Indonesian Borneo: some results confirming the need for new silvicultural prescriptions
A set of Permanent Sample Plots (PSP) was established in the lowland mixed dipetrocarp forest within PT Inhutani II concession at Malinau (2º45’ – 3º15’N, 116º30’), East Kalimantan (Figure 1). They were designed for comparative studies of conventional logging (CNV) and reduced-impact logging (RIL...

STREK is an acronym of "Development of Silvicultural Techniques for the Regeneration of logged-over rain forets in East Kalimantan". The objectives of this project were to develop management rules leading to sustained productivity of the forests in this area, which are the main suppliers of wood ...
These guidelines form the basis for defining the initial set of activities to be classified as Reduced-Impact Logging (RIL). They have been adapted to and will be tested in the local conditions that occur in the lowland and hill dipterocarp forest of the Bulungan Model Forest project in East Kali...

Forest inventories conducted in Indonesia (Berau District, East Kalimantan) highlighted the main festures of the Dipterocarpaceae primary forest. Dipterocarpaceae species accounted for 25% of the stand (diameter > 10 cm), 50% of the basal area and 60% of the standing volume. In three primary fore...

Overview of approaches and methods
The structure and species composition of the primary lowland dipterocarp forest in Berau is presented. This study mainly focuses on the primary forest based on 3 control plots of 4 ha each, totalling 12 ha, where 93% of the trees (dbh (10cm) were identified at the taxa level. Tree identification ...
Timber harvesting was investigated both in terms of commercial timber volume extracted and impact on residual stand. Conventional and Reduced Impact Logging (RIL) techniques were compared on the basis of pre- and post-harvesting stand inventories. Timber volume extracted averaged 87 m3 ha-1 and t...
