The present research aims to know the regeneration status of community managed Shorea robusta (Sal) forests; managed for 6-21 years in Tanahun district, a part of Gandaki Province, Nepal. These forests were categorized into two groups according to management duration (more than 10 years and equal or less than 10 yrs). The regeneration status of the forest was estimated by calculating the density of each species in each developmental phase (seedling, sapling and tree). The total tree density of community forest managed for more than 10 years (MCF forest; 1230 plants/ha) was less than the community forest managed for equal or less than 10 years (LCF forest; 1314 plants/ha). The results suggest that the size class distribution of the trees resembling inverse-J shaped indicates the good regenerating capability of both forests. After the handover of forests to the community, Sal density had increased rapidly in both the forests. Community management had a significant positive impact on the regeneration of the forest, and thus, the productivity of the forest. Thus, the study of regeneration of forest trees has important implications for the conservation and management of natural forests.

Regeneration patterns of species population can address climate change by adaptive evolution or by migrating association to survival in their favorable climate and finally decide the particular forest future. This research examined the status of regeneration and carbon sequestration potential in tropical Sal (Shorea robusta) forest of Kanchanpur district, Nepal. For the study, a total of 63 concentric sample plots were investigated by using systematic sampling with 0.5% sampling intensity. Regeneration status of forest was estimated by calculating the density of each species in each developmental phase. The above-ground carbon stock of trees species were estimated using allometric equations. The studied forests had good regeneration status and Shorea robusta was the dominant species in terms of regeneration and carbon stock. Ramnagar community forest had greater number of seedling, sapling and tree than that of the Ganesh community forest. Reverse J-shaped population curves were recorded at both the study sites. This study provided information about the regeneration status, structure, composition and carbon sequestration potential of tree species which is very necessary for conservation and sustainable management of community forests. Studies indicate that community management has increased the carbon stock of forests and also has promoted the productivity of forests by altering the structure and composition of the community forests.

The study was conducted in the Pragatisil Community Forest, Kaski District, Nepal in 2012 to assess the regeneration status of Sal (Shorea robusta) seedlings, its growth and plant diversity. A plot size of 25 m × 20 m was employed for trees, 10 m ×10 m for poles and 5 m × 5 m for regeneration. The growth parameters measured were dbh and height. A factorial arrangement of treatments was employed; the treatments being slope and aspect. The results showed that there was significant (p<0.05) effect of slope on dbh and basal area whereas there was no effect of aspect on growth parameters measured in the Pragatisil Community Forest. The regeneration of Sal was satisfactory (6,126 seedlings/ha), and there were 32 plant species in this forest. As there was higher basal area per ha in the Pragatisil Community Forest, it is recommended to have thinning of 40% of basal area for enhancing growth of remaining stems.Banko Janakari, Vol. 23, No. 2, 2013

Scientific forest management (SciFM) ensures improved productivity and healthy forests that are crucial for the economic development and prosperity of forest-dependent country like Nepal. This study analyzes the effects of the silvicultural intervention on the regeneration of Sal (Shorea robusta), plant species diversity, and income through the flow of forest products in the Patela Community Forest in Kailali District of Nepal, where Sal (S. robusta) forest has been managed under an Irregular Shelterwood System with 80 years of the rotation period since fiscal year 2017/18. The vegetation sampling was done by the quadrat method based on the principle of stratified random sampling from the managed and unmanaged parts of the forest. The climate based site productivity was analyzed. The profitability of scientific forest management was analyzed by income and cost incurred in managing the forest. The study revealed the promising regeneration of S. robusta in the managed areas compared to the unmanaged area. The silvicultural intervention had a significant negative effect on plant diversity showing an increase in the concentration of dominance of S. robusta. An implementation of SciFM plan generated a total net benefit of 187,000 US$ in the last 2017/18, and 2018/19 fiscal years. This study recommends existing natural forests to be managed based on sound silvicultural principles to improve the degrading nature of the productive forest that can generate revenue for the country and opportunity for community development.

Present study aims to explore forest composition, fuelwood harvest and regeneration status in two community forests of central Nepal. We carried out our study in different periods of 2007 and 2008. Household surveys were conducted to find the condition of fuelwood harvest and people dependency on community forest. Community forests of Nawalparasi districts are dominated by Shorea robusta whereas community forests of Syanja district are dominated by Castanopsis indica and Schima wallichii with highest IVI value. Percapita fuelwood consumption and domestic animals are higher in Nawalparasi district than in Syanja district. Grasses are the main source of fodder in Nawalparasi district whereas trees in Syanja district. Farmland is the main source for fodder in both the districts but even higher in Syanja district. For fuelwood people depend on forest than the farmland. Dominant tree species in Patapati Lulpani Community Forest (PLCF) showed reverse J-shaped size class distribution indicating sustainable regeneration whereas dominant tree species in Gamtam Community Forest (GCF), Dhuseri Community Forest (DCF) and Bhedawari Community Forest (BCF) showed poor regeneration status.

The Community Forestry has been the most effective means of managing common forest resources in Nepal. Besides rehabilitating degraded hills, improving environment and contributing to the rural livelihoods, community forestry is claimed to be a major means of biodiversity conservation. It is also argued that the prevalent approach of community forest management threats to the conservation of biodiversity. This paper is based on the findings from two community forest user groups from Central Nepal and argues that the users’ innovative practices of active forest management favor biodiversity conservation. The study has documented users’ innovations to conserve biodiversity in community managed forests.

Landslide causes massive loss of lives and properties along with intangible losses in mountainous regions. Yet such intangible losses in ecosystems are rarely considered. The present study assesses the tree biomass lost due to Jure landslide in Sindhupalchowk that destroyed 71 hectare of land. Altogether, 12 plots (250 m2) were sampled through systematic and purposive sampling technique. The total tree biomass was estimated using allometric equation. The study recorded 21 tree species in which Schimawallichiii (Korth.), Lagerstroemia parviflora (Roxb.), Shorea robusta (Gaertn.), Alnus nepalensis (D. Don), Phyllanthus emblica (Linn.) and Celtius australis (Linn.) were dominant. Schima wallichiii had the highest density (320 individual ha-1) and frequency (92%). The total biomass of tree species was 216 ton ha-1 in which Schima wallichiii constituted the highest total tree biomass (82 ton ha-1). In 71 ha landslide area, the landslide caused loss of 15,336 tons of total tree biomass, which equals to 56,283 tons CO2 equivalents. These findings are relevant for assessing post-landslide impacts on the mountain environment. Furthermore, to reduce carbon emissions resulting from forest loss, mitigation of landslide is crucial.Journal of Institute of Science and TechnologyVol. 21, No. 1, 2016,Page: 65-70

A significant volume of wood was lost due to wood defects; however, few studies were done to quantify wood loss by wood defects. This study was focused on quantifying wood loss by heart rot, especially hollowness in Shorea robusta. The study was conducted in Tileswornath community forest of Rautahat district. The data were collected from the felling site of the regeneration felling block of Tileswornath community forest. 44 trees were selected randomly, and tree diameter, total height, and volume were measured. The destructive method was followed as heart rot cannot be visible from the surface. Felled trees were sanctioned into 285 logs and separated based on the hollowness. Hollow diameters at both thin end and mid and thick end, as well as length, were measured on the hollow log, and Smalian’s formula was used to calculate the volume of hollowed portion, and volume calculation formula for the cylinder was used to calculate total volume. For the solid logs, mid diameter and length of the log were measured and volume calculation formula for the cylinder was used to calculate total volume. Logistic regression was performed to identify the relation of total height and diameter with the probability of hollowness presence. The study showed that 59% of sampled trees and 34.39% of logs were found to be hollowed due to heart rot. 41.79% volume was occupied by hollow on the hollowed log. Logistic regression discards the relation of height to the hollowness but signified the relation of diameter to the probability of hollowness presence. Before implementation of scientific forest management modality, the timber retained in stump per tree was found as 0.18 cubic feet.

Sustainability Principles

Management of natural forests in Costa Rica allows timber extraction in so far as it is guaranteed that the logging activities comply with diverse Sustainability Principles, Criteria and Indicators (PCIs). These are hierarchical and complex systems used, ex-ante in the formulation and approval of the Management Plan but have not been used for ex-post evaluation of managed forests. Development of sustainability evaluation systems that include few criteria is highly recommended. In that sense, the choice experiments contribute to simplification of the initial system of decision making, complementing a complex system of PCIs that permits detailed analysis of the management units. In this study, a choice experiment was included in a Delphi application and 5 key variables were identified to evaluate the sustainability of managed natural forests. These variables are, in order of importance—technical, legal and administrative conditions; external financing conditions; production performance; costs of preparing the Management Plan; and payment mechanisms for environmental services. The definition of these variables confirms not only that the technical, legal and administrative conditions are critical for sustainability but also that they could reflect the type of governance involved in sustainability forest management.

Private Management

This study compares the management performance of timber production among three management systems in Nepal: private forestry, community forestry with collective management, and community forestry with centralized management. While collective management relies entirely on community labor for the whole management, centralized management uses community labor for the protection of forests and hired labor for silvicultural operations, for example weeding, pruning, and thinning. We found that collective community management is less costly for the protection of planted trees but allocates less labor for the management of trees than private management. We also found that centralized management of natural forests leads to higher revenue and profit than collective management. These findings support the hypothesis that, while collective management is more efficient than private management for the protection of trees due to effective mutual supervision, profit-seeking private management or centralized management is more efficient than collective management for silvicultural operations due to superior work incentives. This study, however, failed to compare efficiency of private and centralized management.
