Introduction: to promote sustainable forest management in the natural forests of West Papua, Indonesia, selective logging systems that incorporate low-impact harvesting techniques such as Reduced Impact Logging (RIL) are being adopted.
Objective: to analyze the volume, characteristics, and contributing factors of logging waste generated through RIL-based timber harvesting in two forest concessions.
Methods: logging waste was quantified at both felling sites and landing points, with data collected from two concessions.
Results: the average estimated logging waste was 0.849 ± 0.095 m³ tree⁻¹ (equivalent to 9.339 m³ ha⁻¹), with 79.82 % (0.684 ± 0.070 m³ tree⁻¹) produced at the felling site and 20.18 % (0.166 ± 0.058 m³ tree⁻¹) at the landing point. Logging waste volume varied between concessions: PT WA generated 0.708 ± 0.053 m³ tree⁻¹ (7.788 m³ ha⁻¹), while PT KH recorded 0.989 ± 0.137 m³ tree⁻¹ (11.868 m³ ha⁻¹). At the felling site, the predominant waste components were stumps (29.74 %) and buttresses (21.40 %), while base ends constituted 15.1% of waste at the landing point. The average logging waste was composed of good-quality wood (4.092 m³ ha⁻¹; 42.79 %), defective wood (3.320 m³ ha⁻¹; 33.32 %), and damaged wood (2.465 m³ ha⁻¹; 24.26 %). Timber harvesting Logging efficiency averaged 85.52 ± 0.01 %, with a felling index of 88.54 ± 0.70 % and a skidding grading index of 96.59 ± 1.30 %.
Conclusions: the adoption of RIL improved overall harvesting recovery by 14.4 %, compared to an average of 80.6 % under conventional logging practices.
