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...

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...

One of the objectives of the STREK project was to propose silvicultural methods able to increase forest production, especially in logged-over areas, The area RKL 1 which was logged 15 years ago was the most suitable zone to implement those trials. This study aims to describe the silvicultural tre...


Sist, P.Abdurachman[Liberation thinnings in logged-over forests]Liberation thinnings in logged-over forests

In the frame work of the STREK project, growth and mortality rates were analysed in both primary forest and after interventions such as logging or liberation thinning in logged-over forest. Dipterocarps, the dominant family in the upper storey and the major commercial species, were the particular...

In East Kalimantan (Indonesia), impacts of conventional and reduced-impact logging (RIL) on forest ecosystems were compared on the basis of pre- and post-harvesting stand inventories. There was a positive and significant correlation between the proportion of trees damaged by felling and the densi...

This report describes Reduced-Impact Logging(RIL) which will be implemented in the lowland and hill dipterocarp forest of the Bulungan Model Forest project in East Kalimantan, Indonesia. It is anticipated that through the implementation and supervision of the RIL practices described in this docum...

Timber harvesting was investigated both in terms of commercial timber volume extracted and impact on residual stand. Conventional (CNV) and reduced impact logging (RIL) techniques were compared on the basis of pre- and post-harvesting stand inventories. The timber volume extracted averaged 87 m3 ...


Bertault, J.G.Sist, P.[An experimental comparison of different harvesting intensities with reduced-impact and conventional logging in East Kalimantan]An experimental comparison of different harvesting intensities with reduced-impact and conventional logging in East Kalimantan

Reduced-impact logging (RIL) and conventional techniques (CNV) were compared in a mixed dipterocarp hill forest in Malinau, East Kalimantan. Damage was evaluated using pre- and post-harvesting assessments in 24 one-hectare sample plots. RIL techniques nearly halved the number of trees destroyed (...

This study is a part of the Reduced-Impact Logging (RIL) studies constituting a developmental phase within a long term research strategy in Bulungan research Forest, East Kalimantan. The sylviculture component of the project was to start logging experiments, focusing on the implementation of RIL ...
