Fellingis an early step in timber utilization process. Efficiencyand effectivity of felling technique, tool type and feller posture will affect the whole timber utilization efficiency. This study was carried out at two timber estates in East Kalimantan and intended to see the effect of two felling techniques and feller postures on felling productivity, fellingcost, as well as timber utilization efficiency. Primary  data collected in this research  included :  felling time, volume  of  felled timber, productivity, felling efficiency, stump height and felling cost. The d

Tree felling is an important component of the forest harvesting system. A skyline-assisted felling technique (locally known as the ‘sandat’ felling technique) is used in private forest harvesting in Probolinggo, East Java, Indonesia, as an alternative to the conventional felling technique. This felling technique is used in private forests planted with an agroforestry pattern. Private forest farmers have recognized the technique as an effective way to protect multi-purpose tree species, especially coffee plants, but the technique’s efficiency is not yet known. The study analyzed the costs and p

Directional felling is a technique that directs fallen trees in a predetermined direction to minimize damage to residual stands and understory plants and facilitate subsequent stages of timber handling. One of the felling techniques used in private forest harvesting was the rope-assisted directional felling technique. The study aimed to analyze and evaluate the effectiveness of the rope-assisted directional felling technique in private forests. The study was conducted in a private forest managed with an agroforestry system in Probolinggo, East Java. The number of sampled trees was 31 trees. Th

Agroforestry is a cropping pattern that is commonly applied to private forest management in Indonesia. Agroforestry based private forest is a land-based silviculture that incorporates forestry plants with agricultural crops, plantation crops, and multi-purpose plants. One of the felling techniques used in agroforestry based private forests is the sandat-felling technique (SFT), which is a rope-assist felling technique. The felling technique was used to protect the remaining stand of the agroforestry based private forest. This technique is an innovation in the harvesting of agroforestry based p

Felling and skidding are essential in the timber extraction process. But on the other hand, residual stand damage can’t be avoided. This study aimed to analyze the impact of conventional and improved felling and skidding techniques on residual stands in natural forests. Three observation plots were developed to identify the types, numbers, and criteria of residual stand damage due to both techniques. The criteria were categorized as a) minor damage (<25%), b) moderate damage (25–50%), and c) major damage (>50%). It showed that the conventional felling and skidding technique caused damage

This study was carried out in 2005 at a peat swamp forest company in Jambi. The aim of this study was to find out a technique to increase the utilization of renghas wood in a peat swamp forest by implementing the lowest possible felling technique (LPFT) and  the conventional felling technique (CFT). Data collected in this study were: working time, log volume, waste volume, productivity, efficiency, stump height and felling cost. Two data categories were analyzed with respect to their possible differences by using a t-test. The study showed that the implementation of LPFT produced better r

Given its complexity, directional felling is considered one of the most dangerous activities in the exploratory phase of forest management projects for timber obtention. Therefore, detailed studies of the variables influencing its execution are necessary. The present research was conducted in the Tapaj&oacute;s National Forest, Brazilian Amazon, and analyzed 1,075 trees logged using the directional felling technique in a 504.30 ha area. To better understand directional felling, the studied variables were subjected to descriptive analyses and principal component analysis, a multivariate pro

In terms of felling the old palms, there are two techniques for oil palm replanting: conventional and underplanting. The conventional method involves felling all of the old palms at once. Under the underplanting technique, on the other hand, the old palms are felled in stages, and the new palms are planted among the remaining old palms. The purpose of this study was to compare the performance of immature oil palms when replanting old palms using conventional and underplanting techniques. The research was conducted in Kebun Rambutan, PT Perkebunan Nusantara III. In comparison to the conventiona

The Tree Faller’s Manual is an essential handbook for forest operators and others who need to fell trees manually using a hand-held chainsaw. This manual builds on the information provided by the Chainsaw Operator’s Manual. Tree felling is a high risk activity. Many fatalities and serious injuries have occurred as a result of being struck by falling trees, dislodged tree limbs or other dangers in the area. Most of these accidents are caused by using unsafe felling techniques and not following safe work procedures. This manual will guide the faller to safer work techniques. The manu

Forest resources in the arid and semi-arid of Sudan are experiencing significant fluctuations in tree cover and ecological functionality. This study aims to bridge this gap by utilizing multi-temporal Landsat imagery and mapping forest cover change in the Nabag Forest Reserve (NFR) in South Kordofan State, Sudan. For this assessment, two cloud-free images (TM from 2011 and OLI from 2021) were downloaded and analyzed using ArcMap 10.7 and ERDAS 2014 software. Supervised classification techniques were applied, corroborated by GPS point verification and field surveys, to quantify changes in fores

Clear-felling, a predominant method for forest regeneration in areas with wet soils, has profound implications for greenhouse gas (GHG) emissions. This technique, by removing the forest cover, exposes the soil to increased sunlight, which can raise soil temperatures and enhance decomposition rates. Consequently, this process can significantly boost the emissions of carbon dioxide (CO2) and nitrous oxide (N2O). The absence of canopy cover also impacts soil moisture due to the decrease in plant transpiration, potentially leading to conditions that promote anaerobic processes in wet soils, thereb
