“…Since trees during their initial stages of growth i.e., when their DBH is lower will thus sequester less carbon but gradually as it increase in DBH would accumulate more carbon. Moreover, it has been observed younger trees grow much faster than older trees as also studied by Chisanga et al (2018). This study was in conformity with the findings of Huston and Marland (2003), who showed that carbon sequestration depends not only on rates of productivity, but also on the size of tree.…”

The present study was conducted during 2018−2019 to estimate biomass, carbon storage, CO2 sequestration rate, CO2 mitigation potential and biomass energy of dominant tree species like Pinus roxburghaii, Quercus oblongata, Cedrus deodara, Pinus wallichiana grown along the National Highway-22 (Shoghi−Shimla−Dhali) bypass, Himachal Pradesh, India. Present investigation was carried out by non-destructive method. About 13,967 trees were cut down during road expansion along National Highway-22. The trees <20 cm dbh dominated the structure of stand density in the study area. The diameter class IV (10−19 cm dbh) showed highest stand density among all the species occurred in study area. Among species, the proportion of Pinus roxburghaii was 64.73%, 74.22% for Quercus oblongata, 73.27% for broad leaves, 53.64% for Cedrus deodara and 51.86% for Pinus wallichiana under class (10_20 cm dbh). The maximum biomass of 2205.3 t ha-1 was observed for Quercus oblongata. Total carbon ranged from 139.26 t ha-1 to 1102.61 for diameter class 10−19 cm dbh to IE>100 cm dbh. The total carbon sequestered rate was found to be 10,306.57 t ha-1. The total CO2 mitigated potential was estimated to be 7498.24 t ha-1 with average biomass energy of 4319.88 t oil equivalent. The study revealed that Quercus oblongata was the major contributor to the total carbon loss and has highest proportion of 39.36% among all species.

“…Different natural and anthropogenic activities in the forest floor promote SOC accumulation by exposing it to higher levels of microbial activity [32]. Counting all these points, elevational gradients could become the most powerful "natural triggers" for monitoring the ecological and evolutionary responses of biota to environmental changes [33][34][35].…”

Species Diversity, Growing Stock Variables and Carbon Mitigation Potential in the Phytocoenosis of Monotheca buxifolia Forests along Altitudinal Gradient across Pakistan

et al. 2022

The sub-tropical broadleaved forests in Pakistan are the main constituents of the ecosystem services playing a vital role in the global carbon cycle. Monotheca buxifolia (Falc.) A. DC. is an important constituent of these forests, encompassing a variety of ecological and commercial uses. To our best knowledge, no quantitative studies have been conducted in these forests across the landscape to establish a baseline for future monitoring. We investigated the forest structural attributes, growing stock characteristics and total biomass carbon stock and established relationships among them in the phytocoenosis of Monotheca forests along an altitudinal gradient in Pakistan to expand an eco-systemic model for assessment of the originally-implemented conservation strategies. A floristic survey recorded 4986 individuals of 27 species in overstory and 59 species in the understory stratum. Species richness (ANOVA; F = 3.239; p = 0.045) and Simpson’s diversity (ANOVA; F = 2.802; p = 0.043) differed significantly in three altitudinal zones, with a maximum value for lower elevations, followed by middle and higher elevations. Based on the importance values, Acacia modesta and Olea ferruginea are strong companions of M. buxifolia at lower and higher altitudes, whereas forests at mid elevation represent pure crop of M. buxifolia (IVI = ≥85.85%). A similar pattern in stem density, volume and Basal area were also recorded. The carbon stock in trees stratum (51.81 T ha−1) and understory vegetation (0.148 T ha−1) contributes high values in the lower elevation forests. In contrast, soil carbon had maximum values at higher elevation (36.21 T ha−1) and minimum at lower elevation (16.69 T ha−1) zones. Aboveground biomass carbon stock (AGB BMC) of woody trees, understory vegetation and soil organic carbon (SOC) were estimated higher (77.72 T ha−1) at higher and lower (68.65 T ha−1) elevations. Likewise, the AGB BMC exhibited a significant (p < 0.05) negative correlation with elevation and positive correlation with soil carbon. We concluded that lower elevation forests are more diverse and floristically rich in comparison to higher altitudinal forests. Similarly, the biomass carbon of Monotheca forests were recorded maximum at low altitudes followed by high and middle ranges, respectively.

“…Our study clearly demonstrated wide variations in physical and chemical properties of soil across various land use systems down the soil profile. The literature also suggests that the physico‐chemical properties of soil vary depending upon existing land use and its management regimes (Chisanga et al, 2018; Juhos et al, 2019; Silva‐Olaya et al, 2022). The observed range of BD, porosity and pH in this study corroborates well with the previous studies on various land use systems ranging from agricultural, horticultural, pasture, fallow/wasteland to rangeland of the NWH region (Bargali et al, 2019; Bargali & Bargali, 2020; Debnath, Narayan, et al, 2020; Loria et al, 2016; Meena et al, 2018).…”

Temperate fruit farming in fragile lands of the Northwestern Himalayan region: Implications for subsoil nutrient availability, nutrient stock and soil quality

et al. 2022

In recent years, soil fertility in the Northwestern Himalayan (NWH) region has deteriorated partly due to accelerated soil erosion but mainly due to ineffective nutrient management for field crops. However, it is largely unknown whether long‐term temperate fruit farming has adverse effects on the soil fertility in NWH or not. Therefore, we conducted a study with the purpose of evaluating the impact of different land uses in the NWH ecosystem, namely: peach orchard (PO), apple orchard (AO), fertile‐fallow land (FL), and barren land (BL) on soil physico‐chemical characters, nutrient storage capacity, and soil quality index (SQI), along a soil‐depth gradient. A total of 116 composite soil samples [four treatments (i.e., land uses), 4‐ soil depths (0–0.2, 0.2–0.4, 0.4–0.6, and 0.6–0.8 m) and 5, 9, 9, and 6 replications for PO, AO, FL, and BL systems, respectively] were collected for laboratory analyses. Across depths, the soils under temperate fruit plantations had better soil physical conditions (i.e., lower bulk density and higher porosity) over FL and BL lands. The soils in this study can be categorized as slightly acidic to near neutral in soil reaction. Soils under temperate fruit plantations (PO and AO), averaged over depths, had significantly (p < 0.05) less quantity of soil organic C, available nutrients (i.e., primary‐, secondary‐, and micro‐nutrients), nutrient storage capacity, and indices of soil quality, as compared to FL lands. These unfavourable effects were augmented in subsoils (0.2–0.8 m) than topsoils (0.0–0.2 m) affecting secondary‐ and micro‐nutrients more than primary‐nutrients. Results further revealed that these lands display a less favourable (i.e., very high) C:N ratio that could easily be degraded if brought under intensive farming. Restoration of depleted soil fertility in temperate fruit‐tree‐based ecosystems of NWH could be achieved through incentive‐based building‐up of soil organic matter and adoption of a soil‐test‐based nutrient management regime.
