Community forests play a vital role in sustainable development and storing carbon stock to mitigate global warming. This study aimed to assess the plant diversity, carbon stock and regeneration status of two Shorea robusta forests managed by the community - Manehara Community Forest (MCF) and Siddhanath community forests (SCF) of Kailali district, Nepal. These two forests differ in the moisture regime- MCF is with ponds and streams and is mostly wet, but SCF is primarily dry with no ponds and streams. To examine vegetation status and carbon stock in these two forests, twenty circular plots of 20 m radius was laid in each forest using stratified random sampling. Within each main plot, two subplots of 5m radius and three subplots of 2m radius were laid to study shrub and herb characteristics, respectively. Soil sampling was also done to analyze the role of soil moisture in carbon stock and regeneration. For this, soil samples of each plot were collected up to 20cm depth. Altogether 100 plant species were recorded from the study forests. Tree and shrub diversity was higher in MCF than in SCF, but herb diversity and seedling numbers were higher in relatively dry SCF than in MCF. The carbon stock of MCF (92.99t/ha) was higher than in SCF (51.94 t/ha). In both forests, carbon stock increased with the increasing basal area (P = 0.0001). A significant strong positive relationship (P = 0.0001) between density and carbon stock was found in SCF, but this relation was weak (P = 0.018) in MCF. Both community forests were fairly regenerating with a good number of small aged individuals, SCF shows an inverted J shaped density diameter (d-d) curve, whereas MCF shows a bell-shaped d-d curve.

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

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 study was conducted to find the net carbon stock in the Sal (Shorea robusta) forest in Bagdaila Chisapani community forest of Dang district, Nepal. The inventory was done by a stratified sampling technique with 0.5% sampling intensity taking into account the woody plants with ≥ 5cm DBH. A total of 49 sample plots of radius 8.94m and 5.64 were established to measure tree biomass and sapling biomass respectively in the forest. The mean above-ground carbon (AGC) was 160.4 t ha-1 and the mean below-ground carbon (BGC) was 24.1t ha-1. The mean total carbon stock in the study area was estimated to be 99.02 t ha-1; of which maximum carbon stock of 143.51 t ha-1 was found in block number 5. Sal was the major tree species in the CF. The biomass and carbon content in this forest is found quite low as compared to other studies in the Sal forest and other tropical forests which were due to the presence of tree stands of less diameter and height. This study would be helpful in the long-term management of forests, planning, and research purposes. The data from this study could also be taken as a reference document for the participation of community forests in carbon accounting under the REDD+ scheme in Nepal.

Different plant species have different capacity of carbon sequestration but it is not assessed yet in Nepal. Therefore, this study was done to assess the species-wise carbon sequestration in two periods in forests. Three collaborative and three community forests were selected for the study. The selected forests were surveyed using GPS and mapped and stratified into tree, pole, and regeneration. Specifically 32, 33, and 31 samples were collected from Banke-Maraha, Tuteshwarnath, and Gadhanta-Bardibash collaborative forests, respectively, while 30, 25, and 22 samples were collected from Chureparwati, Buddha, and Chyandanda community forests correspondingly. The sample plots were of 25 m × 20 m for tree strata. The diameter and height of plants were measured and samples were collected for three consecutive years. The estimated carbon stock of Shorea robusta was the highest 35.93 t ha−1 in 2011 which was slightly decreased to 34.43 t ha−1 in 2012 and reached 32.02 t ha−1 in 2013 in Banke-Maraha collaborative forest but it was the least 7.97, 8.92, and 10.29 t ha−1 in 2011, 2012, and 2013, respectively, in Chyandanda community forest. The highest carbon sequestration was recorded about 5.02 t ha−1 of Shorea robusta in Chyandanda community forest in between t2013 and t2012.

Resource Needs

The paradigm shift in park management from a fortress mentality to the participatory concept is represented as a major transformation in the conservation discourse in Nepal. The involvement of local people in the management of resources in national parks has been significantly effective in attaining the conservation goals of conserving wildlife without compromising the basic forest resource needs of the local people. Nevertheless, some economically important species have not been afforded due consideration during such management. This study investigates the species composition and regeneration status of Shorea robusta (Sal) and Terminalia alata (Saj) in 4 Buffer Zone community Forests of Bardia National Park in Thakurdwara VDC in 1999/2000, 2002/2003 and 2005. The results reveal that Shorea robusta (Sal) and Terminalia alata (Saj) both constituted a large proportion of species diversity but that their regeneration from seedlings to established stages were low, suggesting vulnerability of this forest and their sustainability at risk due to their dwindling conditions. Immediate management concern of these economically important forest tree species is warranted.

Purpose This study aims to assess the biodiversity of the study area and estimate the carbon stock of two dry deciduous forest ranges of Banka Forest Division, Bihar, India. Design/methodology/approach The phytosociological analysis was performed and C stock estimation based on volume determination through nondestructive methods was done. Findings Phytosociological analysis found total 18,888 [14,893 < 10 cm (diameter at breast height) dbh] and 2,855 (1,783 < 10 cm dbh) individuals at Banka and Bounsi range with basal area of 181,035.00 cm2 and 32,743.76 cm2, respectively. Importance value index was highest for Shorea robusta in both the ranges. Species diversity index and dominance index, 1.89 and 1.017 at Banka and 1.99 and 5.600 at Bounsi indicated the prevalence of biotic pressure. Decreased dbh and tree height resulted in a lowered growing stock volume as 59,140.40 cm3 ha−1 (Banka) and 71,306.37 cm3 ha−1 (Bounsi). Total C stock at Banka and Bounsi range was 51.8 t ha-1 and 12.56 t ha−1, respectively where the highest C stock is recorded for Shorea robusta in both the ranges (9.8 t ha−1 and 2.54 t ha-1, respectively). A positive correlation between volume, total biomass and basal area of tree species with C stock was observed. R2 value for Banka range was 0.9269 (volume-C stock), 1 (total biomass-C stock) and 0.647 (basal area-C stock). Strong positive correlation was also established at Bounsi range with R2 value of 1. Considering the total forest area enumerated, C sequestration potential was about 194.25 t CO2 (Banka) and 45.9 t CO2 (Bounsi). The valuation of C stock was therefore US$2,525.25 (Banka) and US$596.70 (Bounsi). Practical implications The research found the potentiality of the study area to sequester carbon. However, for future, the degraded areas would require intervention of management strategies for restoration of degraded lands and protection of planted trees to increase the carbon sequestration potential of the area. Originality/value Present study is the first attempt to assess the phytosociology and estimate the regulatory services of forest with respect to biomass and carbon stock estimation for the Banka forest division of Bihar.

Abstract BackgroundAfter a successful implementation of community forestry practices, since 2003 collaborative forest management has been implementing in Nepal. Due to naive approaches of managing forest land in Nepal, the information regarding the forest condition under silviculture practices is very low. The purpose of the study was to understand the regeneration status in the harvested plot and make the comparison of crop stands between the thinned and unthinned plot. MethodHarvested, Thinned, and Unthinned block of Tilaurakot Collaborative Forest was chosen for the study. Eccentric circular plots with radii 11.29m was taken for trees, 5.64m for poles, 2.82m for saplings, and 1.78m for seedling was taken to collect data from each of the selected blocks. Altogether, 71 plots were taken from harvested (11), thinned (30), and unthinned (30) block. Results The result shows seedling and sapling in the harvested block were 14,974 and 3,368 per hectare, respectively. Also, the study identified that the number of seedling and sapling in the thinned block were higher than the unthinned block. However, the growing stock and basal area per hectare in the thinned block were lower than the unthinned block. The number of trees per hectare was lesser in the thinned block (86 per ha) than an unthinned block (140 per ha). Similarly, the number of poles per hectare were lesser in the thinned block (346 per ha) than an unthinned block (370 per ha). Also, the important valve index (IVI) of Sal (Shorea robusta) was found more than other species in harvested, thinned, and unthinned blocks. ConclusionsThe study suggest that the condition of regeneration was better after the opening of the canopy and thinning promotes the growth of trees and undergrowth vegetation. Thus, policy makers should give emphasis on using the silvicultural operations in forest management to maintain the forest health.

The ability of forests in atmospheric carbon sequestration is increasingly gaining attention. Present study deals with the estimation of biomass and carbon stock of the teak plantation in the terai central forest division in Kumaun, Uttarakhand State of India. Very few scientific studies were done regarding the teak plantation and the estimation of its biomass in Kumaun. Therefore this study was carried out in this region to assess the role played by teak plantation in climate change. The information regarding the changes in pattern of carbon storage is vital and important because it can be used by government and policymakers to predict the deposit pattern for changing climate. Three sites i.e., Kamola block (Site I), Kamola beat (Site II) and East Gadappu beat (Site III) were selected for the study. Large scale variations in biomass and carbon stock were noted among all three sites. Site III (East Gadappu) showed the maximum biomass and carbon stock (297.03 tha-1 and 143.18 tha-1) followed by site I (Kamola block) (241.9 tha -1and 117.27 t ha-1) and site II ( Kamola beat ) (175.76 t ha-1and 85.79 t ha-1). Although stand density and total basal area of the forest showed almost similar value on all three sites, still the differences in biomass and carbon stock at all sites indicated the positive contribution of biodiversity as shown in the results and negative implications of human disturbance to the forest.

Present study was carried out to assess the structure and regeneration of Sal forests in Shiwalik region of Kumaun Himalaya. Vegetation analysis and tree canopy density was determined by using quadrat and densitometer, respectively. Density of seedlings, saplings and trees was 490-14067, 37-1233, and 273-863 ind.ha-1 respectively. The basal area was 0.12-5.44 m2 ha-1 reported for saplings and 25.4-77.6 m2 ha-1 for trees. Regeneration of Sal was found good in Sal mixed dense forest followed by Sal open forest and Sal dense forest, respectively. Regeneration of Sal was assisted by the presence of associated tree species as well as the sufficient sunlight availability on ground due to adequate opening of canopy trees in Sal forest. Thus it is concluded that the density of tree canopy, sunlight availability and also associated tree species impacted the regeneration of Sal in the region.
