Reduced impact logging in the dried land natural production forests in Indonesia

Abstract

Timber harvesting in natural production forests in Indonesia is still carried out to his day in the form of a bussines license for the utilization of timber forest products-natural forests (IUPHHK-HA). IUPHHK-HA holders have not fully implemented Reduced Impact Logging (RIL). Forest harvesting activities consisting of felling, skidding, bucking, loading, unloading, and transportation of logs are aimed at without significantly disturbing log production and its environment. The purpose of this review is to provide information on RIL in Indonesia. The collection of data was done by using a desk study. Data on productivity, efficiency, costs, damage to the residual stands, and the impact of RIL on emissions were collected. Several research results showed that: (1) logging productivities generally decreased when compared to Conventional Logging (CL), (2) logging efficiency generally increased when compared to CL, (3) logging costs generally increased in the short term, (4) residual stand damages generally reduced when compared to CL, and (5) RIL has potential to reduce emissions compared to CL. It is necessary to do the following: harvest planning such as mapping and distribution of trees, skid trail alignment, design of landings; harvest preparation such as the opening of skid trails, opening of landing places; harvesting such as determining felling direction, felling, skidding, and closure of harvesting such as closure of skid trails and landings.

Application of Conventional and Improved Techniques in Felling and Skidding to Residual Stand Damages

“…The company surrenders all the timber harvesting activities to the harvesting contractor. Meanwhile, currently, RIL (which was later considered an improved technique in this paper) has the potential to improve logging efficiency while reducing residual stand damage and carbon emissions compared to conventional logging (Dulsalam et al, 2021). Therefore, this study aimed to analyze the impact of conventional and improved felling and skidding techniques practiced on residual stand damage in natural forest concessions.…”
