“…The basal area recorded in study stands (5.2-88.39 m 2 ha À1 ) is either comparable or greater than the values reported for other oak forests in central Himalaya (Rawat & Singh, 1988;Verma & Garkoti, 2019). The study clearly illustrated that the stand and A. nepalensis basal area were strongly correlated with the stand carbon stock (Figure 6).…”

Nitrogen‐fixing Nepalese alder (Alnus nepalensis D. Don.) is a rapidly‐growing pioneer tree species that often forms pure stands in areas affected by landslides, but also occurs mixed with other late‐successional species in the central Himalayas. In this study, we assessed the distribution of carbon in vegetation and soil in a chronosequence of A. nepalensis (3–270 years old) forest stands and evaluated its correlation with the stand and alder total basal area (TBA). The study was conducted in six different naturally occurring forest stands in a chronosequence, viz., alder‐early regenerating (AER), alder‐late regenerating (ALR), alder young‐mixed (AYM), alder mature‐oak (Quercus leucotrichophora) mixed (AMOM), alder mature‐rhododendron (Rhododendron arboreum) mixed (AMR), and alder old‐oak (Q. leucotrichophora) mixed (AOOM) forests. The chronosequence consisted of three young unreserved, AER, ALR, and AYM (age 3–25) and three older reserved, AMOM, AMR, and AOOM (age 80–270) stands. We used structural equation modelling (SEM) to quantify the contribution of various carbon pools on ecosystem carbon stock. Forest carbon stock significantly increased (p < 0.05) with forest age and TBA, indicating that succession is the driving factor of the forest ecosystem processes, carbon accumulation, and therefore, change in vegetation biomass carbon and soil carbon in the chronosequence of A. nepalensis forests. Total vegetation biomass carbon (tree, shrubs, herbs, and litter) contained ~12.54–289.85 Mg ha−1 (79.11–57.77% total carbon stock), and soil carbon (depths of 0–10 cm in AER, 0–30 cm in AYM, 0–100 cm in remaining forest stands) contained ~3.31–210.13 Mg ha−1 (20.8–42% total carbon stock) and positively increased with stand and A. nepalensis TBA. The tree layer biomass carbon stock was considerably higher than the understory (shrubs, herbs, and forest floor). The soil carbon stock was reported to be influenced by the successional stages. Therefore, these findings reflect that the A. nepalensis forest development in the central Himalayas lead to storage of large amount of carbon stock in both plant biomass and soil.

This study aimed to determine the effects of four different development stages of sessile oak (Quercus petrea (Matt.) Liebl) stands on soil organic carbon (SOC) and total nitrogen (TN) stocks in northwest Turkey. According to the diameter at breast height (dbh), sessile oak stands were classified into four development stages namely: a development stage (<8cm), b development stage (8 to 19.9 cm), c development stage (20 to 35.9 cm) and d development stage (36 to 51.9 cm). Soil samples were taken from three different soil depths (0-10, 10-20, and 20-30 cm). Total 72 soil samples were collected from all development stages. Forest floor litters were also sampled from each development stage. Results showed that soil organic carbon varied significantly between the four development stages (R2=0.714, p=0.000) with the highest stocks under the d development stage (55.0 Mg ha-1) and the lowest under the b development stage (10.6 Mg ha-1). Total N stock was highest under the a development stage (3.39 Mg ha-1), whereas it was lowest under the b development stage (1.18 Mg ha-1). About 71% of SOC was deposited in the upper 30 cm of the soil. The forest floor litter also varied between the four development stages with the highest values under the b development stage and the lowest under the a development stage. As a result, the results of the study indicated that sessile oaks can play a significant role in storing organic carbon and nitrogen in the soil. On the other hand, amounts of SOC and TN stocks can be significantly varied according to stand development stages.

The forest carbon stock usually depends on the forest types, forest density, age of forest, size of trees, site quality, wood density, annual precipitation, and species composition. This research aims to analyze the relationship among tree carbon stock, species richness, soil chemical properties such as soil organic carbon, and soil pH in the Forests of Chandragiri Hills, Kathmandu, Central Nepal. Along this forest, five square plots (20 × 20 m2 ) each were established along the two transects at a maximum interval of 100 m. Carbon stock of each tree was estimated by using allometric equation based on measured tree height and DBH. The mean tree carbon stock was found to be highest in Mixed Forest (87.13 t/ha) followed by Oak Forest (52.75 t/ha), and Pine Forest (22.5 t/ha). The tree carbon stock showed significant negative correlation with tree species richness (r = -0.56, p = 0.001). The tree carbon stock showed significant positive correlation with soil organic carbon (r = 0.57, p = 0.001) and soil pH (r = 0.37, p = 0.05). Tree carbon was found positively highly significant correlation with altitude, Soil organic carbon, pH, and Shannon diversity index.
