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...

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...

The CIRAD-Forest Research Programme on the dynamics of humid tropical forests has been in operation since 1974 in collaboration with various national forest research institutes. Research is carried out on a network of experimental plots, of which the most important are in Africa (Mopri, Irobo and...

STREK is the acronym for Silvicultural Techniques for the Regeneration of logged over forests in East Kalimantan, Indonesia project. The Ministry of Forestry of Indonesia and CIRAD-Forìt were the lead the institutions. The Indonesian state-owned company INHUTANI I was the implementation agency in...

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...

Phenological observations have been carried out on all the dipterocarps (except the genera Vatica and Hopea) recorded on 20 ha of mixed lowland dipterocarp forest in the Berau district (Kalimantan Timur, Indonesia). More particularly, a fruiting peak was observed at the end of January 1995. Altho...

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 ...
