Relationship between Tree Species Diversity and Carbon Stock Density in Moist Deciduous Forest of Western Himalayas, India

Landscape level variability of structure and tree species diversity was analyzed in a tropical deciduous forest at Chamela, Mexico. Trees with DBH ≥5 cm were sampled in 21 0.24 ha plots (5.04 ha in total) distributed among six different morpho-pedological land units. Average density was 1,385 individuals ha-1, basal area 15.9 m2 ha-1, and canopy height 6.8 m. Trunks with DBH ≤14 cm accounted for 90% of the entire set. A total of 148 species, 102 genera, and 43 families were recorded. Seventy percent of all species were poorly represented (< 10 individuals ha-1). A Principal Component Analysis (PCA) based on structure and diversity variables showed that plots from the same morpho-pedological land unit were not always located close to each other along the two first axes, but a further PCA based on dominant species clearly divided two groups of plots. Although canopy structure and tree species diversity varied continuously across the landscape, -diversity (evaluated through species similarity between plot pairs) and the identities of dominant species exhibited the clearest distinction. The dichotomy between granitic vs. non-granitic lithology was the condition most clearly related with a lower similarity in species composition and the strongest contrast in the dominant species group.

The study was conducted from January to April 2018 to estimate ecosystem carbon stock and tree species diversity at National Botanical Garden, Bangladesh. Transects line method square plots with a size of 20 m × 20 m were used. So altogether there were total eighty-three sample plots in National Botanical Garden. Above ground carbon (AGC) and below ground carbon (BGC) biomass stock was 192.67 and 31.34, respectively and soil organic carbon mean value of 27.52 Mg ha-1, 21.45 Mg ha-1 and 16.23 Mg ha-1, respectively for 0-10 cm depth, 10-20 cm and 20-30 cm depth. The average number of tree species per hectare was 128 with a mean value of each plot 3.00 to 9.00 species. The average number of trees in National Botanical Garden (233 tree ha-1), basal area (21.45 m2 ha-1) and mean DBH (39.86 cm). Tree diversity range from 0.25 to 1.86 and the mean value of (0.93 ± 0.14) in National Botanical Garden. A relationship such as biomass carbon with the basal area, mean DBH, stem density and tree diversity were estimated. Among these, the relationship between basal area and biomass carbon showed positive significant correlation. Therefore, the results of the study confirmed that the selected botanical garden can serve as a valuable ecological tool in terms of carbon sequestration, diverse tree species and storage of soil organic carbon.

HERIYANTO, N. M., SAMSOEDIN, I. & KARTAWINATA, K. 2018. Tree species diversity, structural characteristics and carbon stock in a one-hectare plot of the protection forest area in West Lampung Regency, Indonesia. Reinwardtia 18(1): 1‒18. — A study of species composition, structure and carbon stock in the lower montane forest in the Register 45B of the protection forest area in the Tri Budi Syukur District, Kebun Tebu Village, West Lampung Regency, Lampung Province was conducted in September 2016. The objective of the study was to undertake quantified measurements of floristic composition and structure of and carbon storage in the lower montane forest at 965 m asl in the protection forest area. A one hectare plot (100 m × 100 m) was established randomly. The plot was further divided into 25 subplots of 20 m × 20 m each to record trees. Quadrats of 5 m × 5 m for saplings and subquadrats of 2 m × 2 m for seedlings were nested in the tree subplots. We recorded 247 trees with diameter at breast height ≥ 10 cm representing 25 species and 19 families, with a total basal area of 59.14 m2. Overall including seedlings and saplings we recorded 31 species. The species richness was very low due to disturbances, and was the lowest compared to that of other forests in Sumatra, Kalimantan and Java. The dominant species in terms of importance values (IV) were Litsea cf. fulva (IV=77.02), Lithocarpus reinwardtii (IV=45.21) and Altingia excelsa (IV=26.95). Dominant species in seedling and sapling stages were Polyalthia lateriflora (IV=27.54) and Memecylon multiflorum (IV=41.58). Biomass and carbon stock of trees with DBH ≥ 10 cm was 50.87 ton/ha and 25.43 ton C/ha, respectively. Regeneration was poor. Structurally and floristically the forest was a developing disturbed forest and the composition will remain unchanged in many years to come. The successions leading to terminal communities similar to the original conditions would be very slow and should be assisted and enhanced by applying ecological restoration through planting tree species native to the site.

Plantation Forests

Tree species diversity, distribution and population structure of tropical forests of Bharnawapara wildlife sanctuary was investigated. The study analyzed the structure of a tropical dry deciduous forest in Chhatisgarh at different sites i.e. closed natural forest, open natural forest and plantation forests of teak. The study was conducted by laying 30 quadrats, each 10 m × 10 m in size at different sites. In total, 246 trees belonging to 28 species of 17 families were recorded from 0.3 ha sampling area. Density ranged between 520 to 990 trees ha-1 subsequently, basal area ranged between 21.50 to 47.30 m2 ha-1. The dominant tree species was Cleistanthus collinus with an importance value index (IVI) of 57.70. Other important species were Terminalia tometosa (IVI 47.10), Lagerstroemia parviflora (36.92), Diospyros melanoxylon (28.42) and Madhuca indica(26.03). The Shannon-Wiener index (H′) ranged between 0.19 to 3.35 and Simpson’s index (C) between 0.12 to 0.95 indicating high tree species diversity of tropical dry deciduous forests. It is evident from the study that natural forest has an edge over plantation forest in terms of species diversity, dominance and richness. Tree species diversity, distribution and population structure provide baseline information for conservation and management of tropical dry deciduous forests in India. Efforts are needed to conserve the natural forest for their diversity and existence. They can also be supplemented with plantation forests to lower the biotic pressure.

Atmospheric Carbon

Carbon is the main casual factor for global warming and climate change. Increased industrialization is known to be the chief contributor to increased atmospheric carbon concentration. Forest ecosystem plays significant role as a major terrestrial carbon sinks that reduces atmospheric carbon concentration. This study assessed the amount of carbon sequestered in the Strict Nature Reserve (SNR) of Omo Biosphere Reserve and the contribution of individual tree species to the carbon stocks. A non-destructive approach was deployed in the study. Systematic random sampling technique was used to demarcate 20 sample plots of 30x30 m. In each sample plot, all tree species (DBH ≥ 10 cm) were identified and measured for their total heights while diameter were measured at breast height (DBH), base, medium and top. Findings indicated 616 stems/ha in the reserve, Strombosia pustulata (63stems/ha) had the highest tree population. Diversity indices showed that the reserve is rich in tree species diversity with potentials for incessant growth due to the existence of young trees in the lower canopy. The high biomass and carbon storage of the tree species revealed the contribution of the reserve to climate change mitigation through co2 absorption from the atmosphere. Ceiba pentandra (9stems/ha) contributed most (26.14%) to the entire carbon stock in the reserve. However higher stem density of tree species hectare-1 did not translate to higher percentage of carbon stock input of the tree species to the entire carbon stock of the reserve. Trees with higher DBH and wood density store more carbon than trees with lesser DBH and wood density. Thus, tree species ability to sequester more carbon is dependent on its DBH and wood density, rather than its population. The need to conserve and increase the tree species diversity is implicated in the study.
