Regeneration status and species diversity of major tree species under scientific forest management in Kapilbastu district, Nepal

In Nepal, scientific forest managementhas been practiced as an effective forest management technique to utilize forest resources sustainably. However, the program has faced many controversies such as intentional logging of only high-valued timber species like Shorearobusta. In addition, few believe this program is severely affecting the regeneration productivity and species diversity in the natural forests. In order to address these issues, we examinedthe regeneration condition and plant species diversity in the stands where scientific forest management operations were carried out. The data related to regeneration status and species diversity were collected using a systematic random sampling of the selected stands. Our results showed good regeneration conditions (Seedling >5000, Sapling>2000) in all the studied stands. The tree species community was dominated by S.robusta(Sal) followed by Schleicheraoleosa (Kusum) and Casia fistula (Rajbriksha). The value of diversity indices of different species varied significantly between felling series. The highest diversity was found in the second year felling series with the Simpsons Index of dominance value 0.6934 and the lowest species diversity was in the first year felling series with a value of 0.8448. It can be recommended that the regeneration felling practice has helped in promoting the regeneration condition and growth.

Processing and marketing of rattan canes in Nepal

This study highlights the processing and marketing of rattan canes with reference to small and medium enterprises (SMEs). The study was designed based on the exploratory research, and was carried out in all the districts of Nepal with rattan enterprises. The main objective was to assess the processing status, supply, and demand including constraints and potentialities of rattan-canes as well as their marketing practices. Systematic random sampling method was followed to take the sampling of rattan processing enterprises of CFUGs. The questionnaire survey was conducted among35 rattan entrepreneurs cum rattan traders and ten executive committee members of CFUGs. The quantitative data was analyzed using Frequency. The study found that hanger, cradle, stools, chairs, and tables were largely manufactured items among all the rattan-cane products. The annual consumption of imported rattan from India and other countries ranged from 850 MT to 1094 MT. Nepalese rattan fulfills 30% of the total demand. The average marketing margin of rattan products was found to be 37-64%. Nepalese rattan is potential to fulfill 70-80% of the total domestic demand of smaller size strands of rattan.

Climate change adaptation governance in Nepal: a framework for sustainable generation of adaptation services

Poverty and high dependency of rural and mountainous households on the natural resources of Nepal have made the country more vulnerable to climate change. On the other hand, there is inadequacy of adaptation services provided to the vulnerable households and ecosystems. Responding to climate change necessitates amore consolidated effort and effective implementation interventions from both the government and non-government actors. To help achieve this very essence, this study has aimed to- (i) review the existing climate change adaptation (CCA) practices, processes and patterns of sustainable resource mobilization and benefit sharing, and (ii) develop a framework that ensures sustainability of resources and equitable sharing of services and benefits accrued from CCA. Consultations with the communities, key state and non-state stakeholders both at federal and provincial levels, reviews of national policies, strategies, periodic plans and programs and field visits were carried out to synthesize the information, document the knowledge, and highlight the gaps pertaining to CCA. Qualitative Content Analysis (QCA) was executed for analyzing qualitative information. Recently, the Government of Nepal has developed a priority framework on sustainable resource management and delivery of adaptation services. In line with the eight themes identified by the National Climate Change Policy (NCCP, 2019), the proposed framework has paid central attention on medium and long-term adaptation planning adhered with Ecosystem-based Adaptation (EbA) and Community-based Adaptation (CbA). Building resilience, reducing vulnerability, increasing capacities, enabling environment, and integrating CCA in development planning have been the focus of the framework. It is found that the delivery of adaptation services to the climate vulnerable groups and poor communities is well reached out through CbA and EbA approaches. It is therefore, crucial in strengthening community- and locally-based mechanisms (such as forest-user groups, farmers groups, agricultural and fisheries cooperatives, and community networks) for sustainable management and delivery of services to facilitate effective adaptation.

Exploring agroforestry systems and practices in the Terai and hill regions of Nepal

This paper explores the status of agroforestry systems and practices in the Terai and hill regions of Nepal. Field survey, semi-structured interview and focus group discussions with the local farmers and stakeholders were conducted to explore the status of the agroforestry system and practices. The study covers forty-three districts, and represents agroforestry systems and practices in the Terai and hill regions of Nepal. Altogether, twelve agroforestry systems and forty-three agroforestry practices were documented in the Terai and hills of Nepal- ten systems in the Terai and seven systems in the hills. Agrisilviculture, agrisilvihorticulture, agrosilvopastoral, agrohortosilvopastoral, homegarden, hortiagriculture, silvofishery, agrosilvifishery, hortisilviculture and apiculture were the major agroforestry systems adopted in the Terai whereas those adopted in the hills included hortiagriculture, agrisilviculture, agrisilvihorticulture, agrosilvopastoral, homegarden, hortosilvipastoral and silvopastoral. The study revealed a gradual emerging scenario of commercial agroforestry systems in these regions although the continuation of traditional agroforestry systems was observed in most of the Terai and hill regions. Insufficient labour availability, fragmentation of land, market price fluctuation, lack of technical knowledge, and wild animal disturbances were some of the major challenges observed in the Terai and hills of Nepal.

Assessment of invasion of Ageratina adenophora in the plantation forest of Nepal

Large-scale plantations of pine species were done in the bare hills of the Middle Mountain region of Nepal during the early 1980s. There is a growing concern on the sustainability of the planted pine forests in the country due to the presence of invasive alien plant species (IAPS). Invasive alien plant species are considered as one of the drivers of forest degradation and deforestation. Ageratina adenophora is one of the problematic IAPS found in the planted pine forests throughout the country. In this study, we employed different treatments to control the invasion of A. adenophora in the planted pine (Pinus patula) forest. The research design included four different treatments, viz., (i) control, (ii) stem felling, (iii) floor clearance, and (iv) stem felling cum floor clearance in one block (Block I), which was replicated in another block (Block II). The data were collected using circular sample plots with 2m radius. The ANOVA and TukeyHSD Tests were applied during the analysis process so as to determine the effects of treatments on invasion of A. adenophora. The "floor clearance treatment" was found to be significantly effective to reduce the presence of A. adenophora in the planted pine forest. On the contrary, the "opening of forest cover treatment" was found to be conducive to this invasive species to invade the area. The "stem felling cum floor clearance treatment" could be an effective strategy to control invasion of A. adenophora in planted forest, but as it demands a high cost, it is likely to be appropriate for small forest areas where promotion of regeneration is of high priority.

Acute cold stress: a potential threat to Royle's pika (Ochotona roylii) survival at Central Himalayas of Nepal

Climate change and its threat to human life and biodiversity are under discussion as the major issue of this century. In this study, pika (Ochotona roylii) was taken as a model animal to study the effect of changing climatic parameters in the Central Himalayas of Nepal. The study was carried out for three consecutive years (2011−2013) in the Kyanjing Valley situated at 3900 m asl, Langtang National Park, Nepal. The study focused on the population density of pika, its lowest elevation distribution, and temperature patterns of the pika-burrows and their immediate surroundings. An iButtons Temperature Recorder was installed inside a pika-burrow for acquiring burrow temperature while the ambient temperature data were obtained from the nearby metrological station. The population density of pika decreased compared to those based on the previous studies. Over the last 25 years, there was a significant increase in the minimum temperature (R2 =0.77) that decreased the snow cover which might have reduced the insulation effect and colder winter to animals living inside the burrow. The temperature inside the burrow was recorded below −5°C for nearly 50% time during January alone and 25% time during total winter days. The environment with a temperature below −5°C could be a threat to the survival of pikas suffering from acute cold stress. Neither there was any record of heat stress (above 25°C) recorded nor there was an increasing trend of the ambient maximum temperature within the LNP during the study period. The lowest elevation of the pika's habitat was found to have shifted 200 m upwards over the last 46 years, indicating that the animals had either migrated upwards or facing extinction locally at lower elevations. However, this short-term study is not sufficient to reflect the effects of climate change on the population of pika in the Central Himalayas. Therefore, a long-term study is required to explore the relation between pikas and their vulnerability to the changing climate

Impact of training on different observers in forest inventory

Observers with different experience levels are involved in the measurement of large number of sample plots during forest inventories, particularly in national forest inventories. However, limited information exist on the quality of data produced by different observers in forest inventory after certain levels of training. This study tries to evaluate the measurement error in forest inventory associated with observers' experience after initial and field-based training for measuring the most fundamental variables- DBH (cm), total tree height (m), and horizontal distance (m) together with bearing (azimuth) to tree from the plot-centre. On completing the second level of training, the mean of the differences in DBH measurement decreased for both the ‘experienced’ and ‘inexperienced’ groups. The mean of the differences in height measurement in the case of the experienced observers was very low as compared to the inexperienced ones. However, the mean of the differences in azimuth measurement showed that the experienced groups were overestimating by at least 1 degree. There was no trend in deviation of measurement for all four variables regardless of tree size. The decrease in the mean and error of differences in measurements after second training showed that field-based training with supervision and training on the use of instruments at laboratories were required for inexperienced surveyors whereas update in working and measurement procedure would be sufficient for the experienced ones.
