Abstract

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 damages of 14.92% dominated by tree crown damage and 16.70% dominated by stem wounds, respectively. The residual stand damage due to conventional felling and skidding technique was 31.62% categorized as medium damage. Meanwhile, improved felling and skidding techniques caused damage of 9.89% dominated by broken trees, and 10.27% dominated by stem wounds, respectively. The residual stand damage due to improved felling and skidding technique was 20.16% categorized as minor damage. The improvement techniques can minimize residual stand damage by 36.24%. Therefore, a good understanding of forest concessionaires regarding RIL principles is necessary for achieving sustainable timber harvesting

Abstract

Forestry research is crucial for forest conservation, sustainable resource utilization, informing policy, promoting development, and enhancing ecosystem understanding. This research is vital for creating policies that ensure forest conservation and support local livelihoods, especially as forests face depletion and degradation threats. Aceh, which contains the largest remaining forests in Sumatra, plays a crucial role in both local and global conservation. Therefore, understanding Aceh’s forest conservation research is the first step to improve conservation practices. This study employs a bibliometric analysis of forest conservation research in Aceh, using Bibliometrix and Biblioshiny to analyze trends. A total of 354 relevant articles were identified using the Scopus database. The analysis shows publication patterns, including document types, article sources, and research affiliations with Syiah Kuala University being the primary contributor. The study also examined the knowledge structure through keyword frequency, trends, and keyword co-occurrences. Results show peer-reviewed journal articles and conference papers as the main publication types, with an increase in publications after 2005, coinciding with Aceh’s post-war political stabilization. Keywords, i.e. ‘forestry’, ‘conservation’, ‘fisheries’, and ‘ecosystem’ were found important. Topic trends revealed interest in forest management, ecosystem services, and disaster-related terms at post-2004 tsunami. Co-occurrence network analysis identified six main keyword clusters, i.e. biodiversity, conservation, land use and land cover change, and sustainable development.
