“…Second, the study uses a commonly collected tree attribute namely diameter at breast height (DBH) to screen the identified species for their carbon storage potential. To maximize the contribution of urban greening to carbon storage and climate change mitigation, it is vital to identify and promote species with these qualities (Soulé et al, 2021). Evidence shows that plantation and management of urban green spaces may store more carbon than nearby suburban or rural areas.…”

Urban tree inventory is a great tool for gathering data that can be used by different end users. This study attempted to chart the species diversity in planted areas and measure their tree diameter at breast height to screen them for the carbon storage potential. A total of 2860 trees belonging to 36 species were recorded in the planted vegetation in parks and avenue plantation. The dominant species were Azadirachta indicia (25.5%), Conocarpus erectus (19.2%), Ficus spp. (15.5%), Tabebuia rosea (9.2%), Peitophorum pterocarpum (9.0%) and the remaining represents (21.6%) of the tree identified in this study. It was found that the highest contribution of carbon sequestration (CO 2 equivalent) is dominated by the Ficus spp. (30.3%) with a total of 3399.3 tCO 2 eq, followed by Azadirachta indicia (25.4%) with a total of 2845.2 tCO 2 eq and Conocarpus erectus (20.4%) with a total of 2286 tCO 2 eq. The entire area has the capability to sequester around 11,213.3 tCO 2 eq and on average of 3.9 ± 0.1 tCO 2 eq. In accordance with the findings, it is imperative for the preservation of a sustainable environment to have vegetation that has the capacity to store carbon. The study suggests, there is potential to increase carbon sequestration in urban cities through plantation programs on existing and new land uses and along roads.

Urban forest carbon sequestration represents an important component of the global forest carbon pool; however, accurate measurements are limited by the inability of existing field stand models to match the specificity of urban greening species. Herein, canopy volume, carbon stock, and the biomass expansion factor (BEF) of 30 Koelreuteria paniculate trees were measured based on terrestrial laser scanning (TLS) and compared to the results of existing wood volume and carbon stock model measurements. The findings revealed that (1) TLS point cloud data were highly reproducible and accurate (root mean square error of tree height and diameter at breast height were ±0.35 m and ±0.33 cm, respectively). (2) Owing to human interference and cluttered urban environments, the BEF of urban greening tree species fluctuated irregularly, considerably different from that of natural forest stands. (3) Leaf carbon stocks were influenced by the size of the voxel. (4) Different tree measurement factors maintained variable degrees of influence on BEF (height under branch, volume of thick branch, crown width, and projected areas of tree-crown produced correlation coefficients of −0.64, 0.54, 0.45, and 0.43, respectively). Accordingly, the carbon stock and BEF of urban greening tree species can be accurately calculated via TLS without damage.

The present investigation was conducted to estimate carbon storage and sequestration by tropical urban trees in Benin City, Edo State, Nigeria. The non-destructive approach was adopted for the study with 65 trees out of 13 species randomly selected from Black Afara (Terminalia invorensis), Aridan (Tetrapleura tetraptera), Orange (Citrius sinensis), Ashoka (Polyathia longifolia), Teak (Tectona grandis), Oocarpa pine (Pinus oocarpa), Umbrella tree (Terminalia mantaly), Flame of the forest (Delonix regia), Opepe (Naucloa diderrichii), Dogoyaro (Azadirachta indica), Weeping fig (Ficus benjamina), Omo (Cordia melleni) and African Oil Bean (Pentacleethra macrophylla). Diameter at breast height, tree height and wood density were used as predicator variables to estimate total biomass, carbon storage and sequestration. The results revealed that estimations for total biomass were 797.23 kg while total carbon storage and total carbon dioxide sequestration were 398.67 kg and 1462.76 kg respectively. Out of the recorded 797.23 kg total biomass, above ground biomass was 632.76 kg while below ground biomass was 164.47 kg. The findings showed that Terminalia mantaly, Delonix regia and Cordia melleni had better carbon storage and sequestration capabilities. Our study recommended the cultivation of Terminalia mantaly, Delonix regia and Cordia melleni species in Benin City as a strategy for mitigating climate change effects and supporting environmental services. The findings of this investigation can offer significant data for urban forestry plans targeted at selecting suitable blend of tropical trees with superior carbon storage and sequestration performances.
