Abstract. Hop NV, Quy NV, Lam NV, Trong PT, Thinh PC. 2023. Woody plant diversity and aboveground carbon stock of Dipterocarpus chartaceus dominant forests in Binh Chau-Phuoc Buu Nature Reserve, South Vietnam. Asian J For: 114-124. The dominant forest of Dipterocarpus chartaceus Symington in Binh Chau-Phuoc Buu Nature Reserve, South Vietnam, has an important ecological role and high conservation value relevant to climate change by storing large amounts of CO2 from the atmosphere. This study assesses the diversity of woody plants and estimates biomass and carbon stocks in different forest states. The study used a typical sample plot setting method was used. Trees with a Diameter at Breast Height (DBH) > 6 cm were measured, and species were identified in 9 sample plots of 50m x 20m in the very poor, poor, and medium forests. A total of 640 tree individuals belonging to 45 species, 34 genera, and 25 families were recorded. The most species-rich family was represented by Dipterocarpaceae (7 species). A total of 15 threatened species (33.33%) belonging to 11 genera from 8 families were listed in the Vietnam Red Data Book (2007) and IUCN Red List (2022). The Margalef (d), Shannon-Wiener (H'), Simpson (Cd), and Sorensen Index (SI) were analyzed for tree species. The study illustrated that medium forests had the highest diversity, followed by poor forests, and the lowest belonged to very poor forests. The ability to accumulate biomass and aboveground carbon stocks varied widely from 48.15 t/ha-196.15 t/ha and 24.07 Ct/ha-98.42 Ct/ha. The medium forest had the highest total carbon stock, followed by the very poor forest and the lowest poor forest. The study provides an essential database for strategies and plans for conserving plant biodiversity and improving the power of CO2 accumulation to adapt to climate change.

Abstract. Armadhan WS, Sari SP, Aji MYMB, Permatasari DP, Amalia BW, Berlin GE, Aszar AS, Indrawan M, Pradhan P, Setyawan AD. 2023. The macrofungal diversity and its potential from the karst forest of Kalipoh Village, Kebumen District, Indonesia. Intl J Trop Drylands 7: 98-105. Indonesia is one of the world's most biodiverse countries, with fungi being one of its most diverse groups of organisms. Many fungi species have been identified and have potential benefits for both living things and the environment. Kalipoh Village Forest, located in the karst area of Ayah Sub-district, Kebumen District, Central Java, Indonesia, offers suitable environmental conditions that provide habitat for various species of fungi. The objective of this study was to determine the diversity and potential use of macrofungi in Kalipoh Village Forest. Data collection was carried out using the survey method, where every encountered fungus was observed and its cap, gills, stalk, color, odor, substrate, and growth habits were recorded. Macrofungal diversity was calculated using the Shannon-Wiener Diversity Index, Simpson’s Diversity Index, Richness Index, and Evenness Index Formula. The exploration results obtained 34 species of macrofungi from 22 genera and 18 families, with most of the species found on weathered logs and leaf litter. Two genera, namely Marasmius and Marasmiellus, were quite common. Based on the index value calculation, the diversity of macrofungi in this area was in the medium category (H'=2.695). It had a high index of richness (R=5.252) and evenness (E=0.764). The high evenness of the species indicates lower dominance, which can also be observed from the results of the high Simpson’s Diversity Index value (0.910). A total of 24 species of macrofungi were known to have the potential as food and medicine.

Abstract. Sharma Y, Gupta T, Gupta RK, Sharma PP. 2023. Effect of forest fire on soil properties and natural regeneration in Chirpine (Pinus roxburghii) forests of Himachal Pradesh, India. Asian J For 7: 125-132. Forest fires have a significant impact on the physical environment, such as land cover, land use, forest ecosystems, and biodiversity. The present study was carried out to quantify the effect of forest fire on soil properties and natural regeneration of Chirpine (Pinus roxburghii Sargent) forests in Himachal Pradesh, India. Data collection was conducted at six different sites in three forest divisions, namely Solan Forest Division, Hamirpur Forest Division and Dehra Forest Division during the year 2020. Burnt and unburnt forests were selected at each site and were compared with each other to study the effect of fire. The results reported that electrical conductivity, pH, available nitrogen, available phosphorus, available potassium were higher in burnt forests when compared to unburnt forests of the studied sites whereas organic carbon (%) was lower in burnt forests as compared to unburnt forests. Seedling density of trees was found higher in burnt forests whereas sapling density was found higher in unburnt forests. This indicates that fire is good for regeneration but frequent fires can be detrimental for the survival of seedlings. Frequent forest fires need to be prevented and that can be done mainly by social awareness and developing strategies for use of pine needles in farming practices and commercial use in paper, pulp and wood industries.
摘要： Sharma Y, Gupta T, Gupta RK, Sharma PP.Sharma Y, Gupta T, Gupta RK, Sharma PP.2023.森林火灾对印度喜马偕尔邦奇松（Pinus roxburghii）林土壤特性和自然再生的影响。Asian J For 7: 125-132.森林火灾对土地覆盖、土地利用、森林生态系统和生物多样性等自然环境有重大影响。本研究旨在量化森林火灾对印度喜马偕尔邦奇松（Pinus roxburghii Sargent）林的土壤特性和自然再生的影响。2020 年期间，在三个森林分区（即索兰森林分区、哈米尔布尔森林分区和德拉森林分区）的六个不同地点进行了数据收集。每个地点都选择了燃烧过和未燃烧过的森林，并将它们进行比较，以研究火灾的影响。结果表明，在研究地点，烧毁森林的电导率、pH 值、可利用氮、可利用磷、可利用钾均高于未烧毁森林，而烧毁森林的有机碳（%）低于未烧毁森林。烧毁森林的树苗密度较高，而未烧毁森林的树苗密度较高。这表明，火灾有利于再生，但频繁的火灾可能不利于树苗的存活。需要防止频繁的森林火灾，这主要可以通过提高社会意识和制定在农业实践中使用松针以及在造纸、纸浆和木材工业中进行商业利用的战略来实现。

Abstract. Kiasari MSh, Sagheb-Talebi Kh, Rahmani R, Ghelichnia H. 2023. Comparison of plant diversity between managed and unmanaged forests in Haftkhal, Mazandaran Province, North of Iran. Asian J For 7: 106-113. The relationship of plant diversity with silvicultural practices has not been fully understood for the oriental beech forests (Fagus orientalis Lipsky), which is a widespread forest tree in the Hyrcanian Region, Iran. The implementation of appropriate forestry practices in the oriental beech forests is therefore crucial in terms of sustainable forest management. Hence, assessing the impacts of silvicultural practices on plant diversity is essential with the regard to sustainable forest management. This study aimed to compare plant species diversity between two managed and unmanaged forest stands in Mazandaran Province, Iran. Forest inventory in an area of 131 ha was performed using in a systematic random sampling with a 150 × 200 m grid size. In addition, the area of sampling was 100 m2 (10 × 10 m). Twenty and thirty sampling plots were established in managed (compartment No. 8) and unmanaged (compartment No. 36) forests, respectively. Shannon-Wiener and Simpson Indices were used to calculate plant species diversity, while Margalef and Sheldon indices were used to determine species richness and evenness, respectively. The results revealed that 50 and 56 plant species were found in managed and unmanaged forests, respectively. Rosaceae, Asteraceae, and Fabaceae were the main families in these studied areas. This study showed that the diversity and richness of plants in the managed forest slightly increased compared to the unmanaged forest. On the other hand, the evenness of plants in the managed forest slightly decreased compared to the unmanaged forest. Changes in plant diversity indices between managed and unmanaged forests were not statistically significant. This research showed that forest management of oriental beech forests using the single-tree selection cutting has not reduced or weakened the diversity of plant species in the managed forest compared to the unmanaged forest.

Abstract. Tapwal A, Kumar A, Sharma S. 2023. Diversity of arbuscular mycorrhizal fungi in the rhizosphere of Angelica glauca and Valeriana jatamansi in NW Himalaya, India. Asian J For 7: 89-97. The diverse mycorrhizal association helps to conserve plant biodiversity, ecosystem function, and the accumulation of pharmaceutically important compounds in medicinal plants. Climate change may have an impact on plant diversity as well as on associated microbiota. The mycorrhizal association and diversity of Arbuscular Mycorrhizal Fungi (AMF) in the rhizosphere of two important medicinal plants of the North-Western (NW) Himalayas were explored during different seasons in two distant locations. The endomycorrhizal association in Angelica glauca Edgew. and Valeriana jatamansi Jones was confirmed by morpho-anatomical characterization of the roots. Microsclerotia, vesicles, and intracellular hyphal coils were found in the roots of both medicinal plant species. The research revealed 24 AMF representing eight genera in the rhizosphere of A. glauca and 19 AMF representing seven genera in the rhizosphere of V. jatamansi. The AMF colonization varied between 55.63-86.34% in the roots of A. glauca and 55.23-78.74% in V. jatamansi. The Spore Density (SD) in the rhizosphere soil of selected medicinal plants was highest during the winter season. The rhizosphere soil of A. glauca exhibited a rich diversity of AM fungi during the rainy season. On the other hand, in various seasons and locations, the maximum diversity of AM fungi was observed during the summer season in V. jatamansi. The genera–Glomus and Acaulospora had the highest species in both study sites.

Abstract. Kirana GR, Wibowo AA, Nurdin E, Wardhana W, Basukriadi A. 2023. Modeling understory shrub diversity related to environmental gradients using Akaike Information Criterion (AIC) in an urban forest in Jakarta, Indonesia. Asian J For 7: 74-80. The urban forest is one form of human-made ecosystem in urban environments. One of the most important components of urban forest ecosystem is understory shrubs. The sustainability of understory shrub community is supported by environmental variables suitable to its growth. Nonetheless, there has been limited information on how environmental variables contribute to the presence of shrubs in particular urban settings. This study aims to model the relationships between understory shrub diversity and environmental covariates, including air temperature, humidity, light intensity and wind speed, using the Akaike Information Criterion (AIC) in Srengseng Urban Forest, Jakarta, Indonesia. The result showed that there were 20 species and 12 families with the most common shrub species being Rivina humilis, followed by Acalypha siamensis, Cordyline fruticosa, Syzigium paniculatum and Caesalpinia pulcherrima. The average Shannon-Wiener diversity index was 0.671 (95% CI: 0.441, 0.901). The AIC models showed that understory shrub diversity was negatively correlated with humidity and positively correlated with light gradients with AIC values of 38.696 and 41.679, respectively. The diversity of understory shrubs in urban forests was significantly supported by sufficient light intensity (R2 = 0.29) and limited by an increase in air humidity (R2 = -0.44). The humidity and light intensity combinations also affect the understory shrub diversity (AIC = 38.900, R2 = 0.256). The results of these studies can help urban forest managers manage urban forests if aiming for biodiversity conservation, especially understory shrub species.

Abstract. Matto AA, Jaikishun S, Ram M. 2023. Impacts of different salinity levels on seedling growth and survival of black mangrove (Avicennia germinans). Asian J For 7: 67-73. Mangroves are important for coastal protection and provide numerous ecosystem services such as breeding, feeding, and nursery grounds for commercial fishes. This research examined the survivability of black mangrove (Avicennia germinans (L.) L.) seedlings in seven salinity concentrations. Growth parameters were collected every ten days, and a post-harvest analysis was done at the end of the data collection period. The results indicated that as the salinity level increased, the growth of the seedlings was reduced. Salinity can affect the different parameters collected in the growth of young seedlings. In the control, which was given zero salinity (0 ppt), it was noted that the growth parameters were not significantly affected. The lower treatments, such as T2 (15 ppt), 3 (30 ppt), and 4 (45 ppt), indicated that the seedlings strive better in these conditions. In treatment 7, which was the highest salinity level (90 ppt), the growth parameters of the seedlings were reduced. The findings of this research indicated that black mangrove seedlings need a low salinity level to have a good growth establishment. Given the adaptability of A. germinans, these mangrove species are anticipated to be flexible to cope with a wide range of future climatic circumstances.

Abstract. Mossie T, Worku H. 2023. Identification and characterization of honeybee flora calendar in Southwest Jimma Zone, Ethiopia. Asian J For 7: 54-66. The study was conducted to identify, characterize and document major bee forages, develop an appropriate flora calendar, their phenology, and pollen potential in the various agro-ecological conditions of the Jimma Zone, Ethiopia. A total of 90 beekeepers were purposefully selected from three districts and interviewed to get primary data. The density and abundance of flowering plants were determined using quadrat sampling techniques. In addition, pollen specimens were collected using pollen traps at seven-day intervals and were also traced back to plant species level under a light microscope. The study has revealed the presence of 141 pollen and/or nectar-source honeybee plant species belonging to sixty-two families in the study area. Herbs were the most dominant bee flora growth forms, accounting for 62 (44%) of a total of 141 honeybee plant species, followed by trees at 48 (34%) and shrubs at 31 (22%), respectively. The herbaceous plant had a greater density value of plant species per plot than did trees and shrubs. One hundred fifteen (81.6%) were both sources of pollen and nectar, whereas fifteen (10.6%) were pollen sources and the remaining eleven (7.8%) were nectar-source plant species. The Shannon diversity index and evenness were found to be 2.8 and 0.6, respectively. This indicated that the study area has a rich bee floral plant species and is suitable for beekeeping. Two main flowering periods of honeybee plants were followed by two honey flow seasons. Therefore, beekeepers should follow the floral calendar of honeybee plants to exploit the potential of the area for honey production.

Ecotourism development as a community-based conservation effort in Ayah Mangrove Forest, Kebumen, Central Java, Indonesia. Asian J For 7: 37-44. The mangrove ecosystem is a transition ecosystem between terrestrial and marine zones affected by tidal waves, water inundation, and high saline water and soil. Mangrove forest plays an important role in physical, ecological and socio-economic aspects. One potential function of mangrove forests from the socio-economic aspect is ecotourism. Ayah Mangrove Forest in Ayah Village, Kebumen District, Central Java Province, Indonesia, has the potential to be developed as a mangrove-based ecotourism area that combines the objective of income generation and mangrove conservation. This research was conducted to examine the conservation and ecotourism efforts by the people of Ayah Village and to assess the local community's perception of the development of mangrove-based ecotourism. The research was conducted in November 2022. Primary data were collected using field observation and interviews with 100 respondents aged 17-60 years using the snowball sampling method, while secondary data were collected using a literature review. The results showed that efforts to protect the Ayah Mangrove Forest area included establishing zones for protection, rehabilitation, and utilization of the mangrove forest. There are also mangrove rehabilitation efforts that involve the community in the form of the establishment of nurseries, mangrove planting, and maintenance of planted seedlings. The local community also carry out garbage cleaning program and public outreach. Besides the conservation aspect, Ayah Mangrove Forest is also utilized for ecotourism objects that generate income for the local community by selling tickets, boats, foods, beverages and souvenirs, tour guides, and parking attendants. Most of the local community has good perceptions and agreed on the development of Ayah Mangrove Forest as an ecotourism area. They are willing to be involved in ecotourism planning and development activities. The community agreed to participate in tour guide activities, selling souvenirs, providing homestays, and participating in ecotourism counseling. Most of the local community has also agreed to form a mangrove conservation community to maintain the sustainability of mangrove forest ecotourism. Nonetheless, support from the government is required, especially in the promotion and rehabilitation programs in the ecotourism development of Ayah Mangrove Forest.

Abstract. Mwaluseke ML, Mwakalukwa EE, Maliondo SMS. 2023. Volume and aboveground biomass models for a dry evergreen montane forest in Tanzania. Asian J For 7: 45-53. Models available for accurately estimating trees and shrubs' volume and aboveground biomass from dry evergreen montane forests in Tanzania are largely lacking. Therefore, this study was conducted to develop volume, and aboveground biomass models for a dry evergreen montane forest of Lendikinya Forest Reserve found in Northern Tanzania. A total of thirty sample trees and shrubs with a diameter range of 5-58.5 cm were destructively harvested and used in this study. Specifically, the study developed (i) the height-diameter model and (ii) the total volume and aboveground biomass models. The following height, volume, and biomass models appear to be suitable for estimating tree height, volume, and biomass of tree and shrub species found in the study site: Height (m) =2.3249 + 6.6101/DBH + 0.2847DBH (R2 = 0.78, RMSE = 1.79, AIC = 164.37), ln(Volume, m3) = -9.845 + 1.915 ln(DBH) + 1.089ln(Ht) (R2 = 0.97, RMSE = 0.296, AIC = -144.18) and ln(Biomass, kg) = -1.666 + 0.853ln(WD x DBH2 x Ht) (R2 = 0.95, RMSE = 0.324, AIC = 224.13). Both models yielded low bias, hence indicating an excellent fit. These models will be useful in understanding the condition of the forest and the potential of this forest in storing carbon hence, the possibility of benefiting from the ongoing negotiations of REDD+ schemes for payment for avoided deforestation and degradation through sustainable management of the reserve.
