Moreover, it plays a crucial role in fostering the social and cultural aspects of the local community. However, the pelawan population has faced great threats due to land conversion, unmanaged forests, and mining. To address these challenges, the local government has shown a commitment to expanding the in-situ conservation areas beyond Namang Biodiversity Park. In order to enhance the conservation status of this species, it is essential to conduct a comprehensive study of the tree’s distribution, morphological characteristics, species delimitation, and genetic diversity. Therefore, this study aimed to obtain information on pelawan distribution, morphological characteristics, species confirmation, and genetic diversity. It was conducted at five natural populations, namely KK (Kota Kapur), BB (Berbura), LAP (Labuh Air Pandan), PN (Pangkal Niur), and LB (Limbung), and the genetic character was observed using ITS and RAPD markers. The first instance of establishing a nucleotide sequence database for pelawan on Bangka Island was also represented, showing the presence of two distinct taxa groups based on ITS sequence nucleotides. Based on morphological characters (bark color and leaves), the two groups were determined to be pelawan merah/orange (Tristaniopsis sp. 1) and pelawan air (Tristaniopsis sp. 2). Significantly, the genetic diversity analysis yielded a range of HE values, from 0.283 (KK) to 0.353 (PN). The PCoA and dendrogram analyses exhibited the formation of a cluster comprising populations from Bangka (KK, BB, LAP, and PN), while LB formed a separate cluster. The result showed significant genetic differentiation between regions and populations, without mixing seeds or seedlings. It was suggested that the conservation strategy for pelawan trees on Bangka Island should be developed with several considerations. In-situ conservation sites should be designated based on the presence of pelawan merah/orange and pelawan air taxa. Additionally, ex-situ conservation plots needed to be established, with at least one location dedicated to each taxonomic group. To preserve the remaining natural genetic resources, KK and LB populations, which had the lowest HE value and different genetic structures should be prioritized. Strategies for ex-situ conservation included KK, LB, and PN. The prioritization of PN for conservation was necessary, and further genetic study of the pelawan should involve larger populations representing the natural distribution of each species.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":" 880","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135186472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected from a trial based on seeds collected from two unimproved, and two improved sources with selection intensities (IS) of 1.1 (10% of trees selected) and > 2.5 (<1% of trees selected). The trial was laid-out in a randomized complete block design with five replications. It was measured at 10 years of age. The leaf oil concentration of the IS >2.5 seed source was significantly higher than for the other sources; a realized genetic gain ranging from 14% to 31%. However, although not significant, this seed source had the lowest leaf biomass. The correlation between gains in oil concentration and leaf biomass was weak and not significant (r = 0.15); while the correlation between oil yield and leaf biomass was very strong and highly significant (r = 0.96). These results highlight the importance of carefully incorporating leaf biomass as a selection criterion in cajuput breeding programs aimed at increasing oil yield.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135570271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SAF provides agricultural and silvicultural knowledge and practices that aims not only for recovering the environmental attributes but also for increasing farmers resilience. However, the benefits of agroforestry related to soil fertility in optimizing the land productivity and governing the community livelihood are often overlooked and have not been well discussed. This review aims to describe how smart agroforestry practices in various regions in Indonesia and several other countries have significantly contributed to maintaining soil fertility and increasing crop production while assuring profitable benefits for the community. This review paper focuses on discussing the role of SAF in sustaining soil fertility and community livelihood in tropical and non-tropical regions. The review article was based on a synoptic review approach to SAF and Soil Fertility-related relevant publications and nationwide experiences. The review compiled and analyzed information from national and international research papers in various online scientific journals, conference proceedings and relevant books, to gain a comprehensive understanding of the topic being discussed. The study utilized a qualitative approach and drew upon primary and secondary sources based on a systematic review. Agroforestry has a significant role in recycling soil nutrients from the materials in the surrounding environment. SAF influences soil fertility physically, chemically and biologically. SAF practices in both wet and dry lands can contribute significantly to the community’s income. This review unveils the latent potential and the role of SAF in sustaining soil fertility that supports the community's livelihood and can serve as impetus for future research.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135885203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DOC in terrestrial and aquatic ecosystems participates in many biogeochemical reactions and processes such as heterotrophic respiration, sorption of metals, and transport of pollutants. In order to understand the connectivity of organic carbon among soil, soil water, and forest streams, we investigated the concentrations and dual carbon isotope ratios (δ13C and Δ14C) of soil organic carbon (SOC) and water-extractable organic carbon (WEOC) obtained from soils beneath two tree species stands, and compared these with stream Δ14C-DOC of the forest watershed. Soil samples were collected at different depths (0–10, 10–30, and 30–50 cm) beneath Japanese cedar (Cryptomeria japonica) and sawtooth oak (Quercus acutissima). Although the SOC concentration was not significantly different between the two tree species, the WEOC concentration ([WEOC]) of soil at 0–10 cm depth under Cryptomeria japonica was higher than that of Quercus acutissima, in general. The δ13C-SOC and δ13C-WEOC increased, while the Δ14C-SOC and Δ14C-WEOC decreased with increasing soil depth. The Δ14C-WEOC was higher than the Δ14C-SOC, indicating that WEOC could be primarily derived from the young, hydrophilic, and exchangeable fraction of SOC, rather than from SOC strongly bonded to mineral soils. However, the stream Δ14C-DOC was lower than Δ14C-WEOC in general, except during summer storms. The 14C-depleted DOC released from deep soils or groundwater might lower Δ14C-DOC of a stream, suggesting that relatively old DOC could be released into streams during baseflow. This is contrary to the results of previous studies that have reported positive stream Δ14C-DOC from temperate forests. The discrepancy warrants future research on forest stream Δ14C-DOC across entire seasons, particularly under Asian monsoon climates.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136210862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic variation changes along the successive generations could affect its genetic stability on wide ranges of sites. The aim of this study is to observe genetic stability in third-generation progeny trials of A. mangium established at three different sites in Indonesia. Analysis was conducted, including single-site and multi-sites analyses for height, diameter, and stem forking that were grouped into two sets of analysis based on the genetic background of the trial: SET01 for the single sub-line and SET02 for the composite sub-lines. Index selection for multiple-traits was then used to identify the family changing ranks for multiple-traits and genetic gain prediction. The results showed that the recurrent selection system adopted in the breeding strategy for single-site analysis could maintain sufficient genetic variance of A. mangium in the third-generation progeny trial. Family heritability was moderate to high for almost all traits. However, a strong genetic-environment interaction (G × E) exists in multi-sites analysis for the single sub-line population (SET01), indicating a less sufficient genetic variation and a low Type B genetic correlation in anticipating a wider range of environment. On the contrary, compositing selected family from several sub-lines (SET02) could diminish the strength of G × E and increase Type B correlation. Selection and genetic gain prediction could be more effective in multi-sites analysis for SET02, but it was less effective for SET01. The results imply that adopting a recurrent selection system in advanced-generation breeding of A. mangium should consider structuring the breeding population. It could be practiced by compositing selected superior families from several sub-lines into one breeding population to maintain high genetic stability, while increasing genetic diversity and productivity.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134947960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, the Indonesian government has promoted community-based forest management schemes. One such scheme, called Hutan Kemasyarakatan (HKm), has introduced Sengon (Paraserianthes falcataria) in smallholder plantations in Rungan Barat, Gunung Mas, Central Kalimantan. However, accurate estimation of biomass is crucial for carbon sequestration credits, but there are no specific allometric models for estimating Sengon above-ground biomass (AGB) in this area. To create a site-specific AGB allometric model for Sengon, 23 trees were felled to collect fresh biomass data. Various tree variables, such as diameter at breast height: 1.3 m (DBH), total height, merchantable height, and stem bole volume were measured for each sample tree. The average wood basic density of Sengon at the study site was also calculated. A total of nine alternative candidate regression equations were fitted and tested to select the best-fit AGB allometric model. Also, to assess the adaptedness of the identified AGB allometric model, comparisons with the models from literature, and comparisons between two interchangeable methodologies (i.e. direct biomass allometric model and biomass expansion factor (BEF)-based biomass estimation) were undertaken. This study has developed a regression function, denoted as to estimate the AGB of Sengon trees in smallholder plantations in Central Kalimantan, Indonesia. The formulated regression function demonstrated better estimation performance compared to common pantropical and regional AGB allometric models. In terms of the BEF-biomass approach, the AGB estimation derived from Smalian’s volume was relatively accurate, close to the mean AGB obtained by the formulated model in this study. In summary, this study proposes using the developed model, based solely on DBH, to accurately estimate AGB and carbon sequestration potential in Sengon trees. The accurate estimation of AGB using this model has additional advantages, including facilitating carbon credit acquisition and informing long-term management decisions.","PeriodicalId":51802,"journal":{"name":"Forest Science and Technology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings show that farmers’ land ownership, cooperative membership, farming experience, market orientation, credit access, and distance to the market mainly determine adoption of agroforestry. Policies that enhance adoption of agroforestry should be consider the formation of farmers’ cooperatives and provision of door-to-door education to uneducated farmers. In addition, strategies for supporting liquidity-constrained households to get continuous and increased access to credit should be put forward.
