Selection Of

Selection of tree species is an important management decision for increasing carbon storage in regional planting programs in China. This study quantifies above and belowground carbon storage by several species in the Desertification Combating Program around Beijing and Tianjin (DCBT). Results show that the total carbon storage of the Pinus davidiana plantation was significantly higher than that of Pinus sylvestris var. mongolica but not significantly differ from plantations of Pinus tabulaeformis and Larix gmelinii var. principis-rupprechtii. Most of the carbon was in the aboveground biomass. These results suggest that tree species have substantial influences on carbon storage, and that species should be considered in improving carbon sequestration potential for afforestation/reforestation projects.

Impacts Of Climate Change

Urban green spaces, particularly trees, have great potential to sequester carbon from the atmosphere and mitigate the impacts of climate change in cities. Large university campuses offer prominent space where such green spaces can be developed in order to offset the increasing greenhouse gas emissions, as well as other benefits. Amity University, Noida, is spread over 60 acres with dense tree plantations in and around the campus. The present study is a sustainability initiative to inventory the tree species on the campus and assess their total carbon sequestration potential (CSP). The above- and below-ground biomasses were estimated using the non-destructive sampling method. Individual trees on the campus were measured for their height and diameter at breast height (DBH), and estimates of carbon storage were performed using allometric equations. There is a total of 45 different tree species on the campus with the total CSP equivalent to approximately 139.86 tons. The results also reveal that Ficus benjamina was the predominant species on the campus with CSP equivalent to 30.53 tons, followed by Alstonia scholaris with carbon storage of 16.38 tons. The study reports that the ratio of native to exotic species is 22:23 or almost 1:1. The present work highlights the role of urban forests or urban green spaces, not only as ornamental and aesthetic plantations but also in mitigating the impacts of climate change at a local level. Higher education institutes have an important role in expanding their green cover so as to act as local carbon sinks.

The Relationship

The potential of carbon sequestration of tree species in the Chintapalle forest range, of Narsipatnam Division, was estimated by using a non-destructive method. The sequestration of 6033 trees belonging to 22 species was investigated; the approximate height of tree species and the diameter at breast height (DBH) were measured for the estimation of CO2 sequestration. The maximum weight of carbon was observed in Pongamia pinnata (L.) Pierre species i.e (37987.06 kg) and the minimum weight of carbon was noted in Phyllanthus emblica L. species i.e is (61.8kg). The total carbon sequestrated by the entire tree species was (2370614.0 kg), The average carbon sequestered was (39865.81 kg). The highest sequestration was noted in the species P. pinnata (L.) Pierre i.e. (139271.95 kg) and the lowest (226.79 kg) was noted in the species P. emblica L. The maximum average DBH with maximum carbon sequestration potential was observed in Ficus benghalensis L. species, with higher total green (AGW) observed in all sites, whereas minimum average DBH with minimum carbon sequestration potential was noted in Bambusa vulgaris species. The regression analysis tests the relationship between two variables. The height of trees has no significant impact on the amount of CO2 sequestered F (32085087175.84, 12946607900) = 2.478262; P ? 0.05, which indicates that the tree height plays an insignificant role in CO2 sequestration (? = 2713.28 P ? 0.05). The dependent variable CO2 sequestered was also regressed on the predictor variable soil organic carbon (SOC) to test the relationship. SOC insignificantly predicted CO2 sequestrated F (5.83, 2.62) = 0.2236; P ? 0.25, indicating that the SOC has an insignificant role in CO2 sequestration (? = 102780.3 P ? 0.05). Insignificant relation was observed between the parameters SOC and height of tree species to the rate of carbon dioxide sequestered, and gave a regression equation of y = 10278x + 50863 with R2 = 0.100; y=2713.285803x-209800.8762 with R2 = 0.55

The study assessed carbon sequestration potential of the identified trees {Gmelina, Mango, Neem, Masquerade, Step and Cassia} along the five selected roadsides in Abeokuta metropolitan. Leaves of the identified trees were plucked, digested in triplicate and analysed for chlorophyll (Ch) A, B and A+B contents using UV-visible spectrophotometer. Obtained data were subjected to descriptive and inferential statistics while correlation analysis for relationship between the analysed leaf Ch contents. Results indicated that leaf chlorophyll contents varied. The ranking of tree to metropolitan vehicular emission along roadsides was Neem < Gmelina < Mango < Masquerade tree. Correlation matrix analysis indicated that production of the Ch contents across the roadsides tree species was not alike and might be due to their specific reactions to vehicular emission. In conclusion, the order of Ch contents might be the tree species potential to withstand vehicular pollutants.

Timber harvesting is an activity in producing wood to supply the lumber industry. However, timber harvesting brought consequences such as decreasing carbon sequestration potential of natural forests. This study aimed to determine the reduction in the potential for carbon sequestration due to timber harvesting in natural forests. Data were collected using non-destructive methods through stand inventory before felling for all tree species, cruising results report, and tree distribution maps. Biomass was calculated using the existing allometric, and carbon stocks were calculated using the Intergovernmental Panel on Climate Change method. The results showed that there were 238 trees (65.29 m3) of stands in the study area (6 ha) based on stand inventory before felling. Potential biomass and carbon storage before trees felling were 16.12 ton ha-1 and 7.58 ton ha-1, respectively. Potential biomass and carbon storage after tree felling were 5.15 ton ha-1 and 2.42 ton ha-1, respectively. Carbon absorption before and after tree felling is 28.37 ton CO2eq ha-1 and 4.44 ton CO2eq ha-1, respectively. Carbon emissions during tree felling was 18.93 ton CO2eq ha-1 (81.00%). The application of environmentally friendly wood harvesting shall be carried out appropriately to minimize a decrease in carbon absorption from timber harvesting.  Keywords: biomass, carbon emission, timber harvesting

This study was carried out to analyze the carbon content in different parts of Alnus nepalensis, and to assess the effect of aspect and altitude in the carbon storage in Alnus nepalensis as well as to quantify the total carbon sequestration (stock) in Alnus nepalensis forest in the mid-hills of Kaski District. The inventory for estimating above and below ground biomass of forest was carried out using stratified random sampling technique. The carbon content in different parts of Alnus nepalensis was quantified using combustion method in the laboratory. For determining the soil carbon content, six soil profiles from each aspect were excavated and soil samples were taken from soil profile up to 1 m depth for deep soil and up to bedrock for shallow soils at the interval of 20 cm. Mean carbon content in stem, branches, leaves and bark of Alnus nepalensis were found to be 40.52%, 33%, 9.56% and 16.4%, respectively. Total biomass carbon sequestered in northern aspect was 30.20 t/ha while for southern aspect it was 39.00 t/ha. In both the aspects higher carbon sequestration was observed at an elevation range of 1200-1300m i.e. 34.8 t/ha and 45.6 t/ha in northern and southern aspects, respectively. Soil carbon sequestration in northern and southern aspects was found to be 113.4 t/ha and 169.30 t/ ha, respectively. The total carbon sequestration potential of Alnus nepalensis forest was estimated to be 186.05 t/ha.

&lt;p&gt;Reducing carbon footprint has increasingly become an important topic regarding the management of industries and universities from different fields. Newcastle University promised to achieve the goal of net-zero carbon dioxide emissions by 2040, and the first process from this ambitious target is to produce a 43% reduction by July 2020, against a 2005/06 baseline. According to the report from Carbon Management Plan 2019 of Newcastle University, there are still 1,720 tons of carbon that should be reduced or offset during this year.&lt;/p&gt;&lt;p&gt;Two farms were investigated in this project: Nafferton Farm (NF) and Cockle Park Farm (CP) . Soil sampling was conducted within each field at three depth increment (0-30 cm, 30-60 cm and 30-90 cm) separately. Except for soil analysis, this study also chooses some plots in the woodlands around two farms to estimate the carbon storage by various vegetation species, and these two sections will offer comprehensive information about the quality and quantity of carbon in two farms.&lt;/p&gt;&lt;p&gt;On average, the percentage of total carbon (TC) from all soil profiles was higher under woodland than crop fields in CP. Because the hectare of crop fields is greater than woodland, the sum of total carbon in individual soil layers from the areas is comparatively larger in crop lands, where C stock is 14,122 tons, 6,017 tons, 5,437 tons for the 0-30 cm layers, 30-60 cm layers and 60-90 cm layers, respectively. Meanwhile, the data is 1, 905 tons, 822 tons, and 648 tons for three soil depth layers in the woodland of CP. In Nafferton Farm, the value of TC from the corresponding soil layers is 17,841 tons, 6,844 tons, 6,177 tons separately.&lt;/p&gt;&lt;p&gt;The results attained so far represent that TC and soil organic carbon (SOC) &amp;#160;in each farm are all statistically significantly different (p&lt; 0.001) with respect to soil depth, but differences were not significant with respect to crop and tree species grown in a single area. Moreover, TC in surface soil of NF is statistically higher (p&lt; 0.01) than that in CP. In Cockle Park Farm, C contents from woodland were considerably higher than those in crop fields (p&lt; 0.001) and the difference of TC and SOC at individual depth layer cannot be ignored. Gross carbon sequestration of plants in woodland is 150.64 tons&amp;#8217; annually, which was calculated by i-Tree Ecosystem Analysis. Simultaneously, the total carbon of trees, including leaf biomass and tree trunks, is in a range of 3,198- 4,096 tons in the woodland of CP. Consequently, the current quality of carbon in topsoil from the whole fields of two farms and the woodland of CP is 35,610 tons which is over four times as high as the estimated carbon emission produced by University in 2019/20 ( 8, 181 tons).&lt;/p&gt;&lt;p&gt;Overall, it is recommended that the management team of university should attach importance to the operation of two farms. The expectation of mitigating 1,720 ton&amp;#8217;s carbon in the short term can be fulfilled if the management department considers converting 58.79 ha crop fields to mixed-species woodland.&lt;/p&gt;

Forest Carbon Storage

Estimation of forest carbon storage can be of great significance to the research on the productivity of terrestrial ecosystem, carbon cycle, and global warming. China has more than 54 million hm2barren hills and waste land suitable for forestation, which provides a great potential for developing carbon sink forestry by means of forestation. This research analyzed the volume increments, volume densities, and carbon contents of 15 analytical samples of five main plantation tree species in North China, includingPinus tabulaeformis(A),Robinia pseudoacacia(B),Populus euramericana(C),Larix olgenisis(D), andLarix kaempferi(E). Results showed that carbon storage dynamic process can be expressed as follows: the ages of quantitative maturity of each tree species are 67a, 40a, 30a, 48a, 49a, respectively; the average wood densities of each tree species at different age classes are 550.93 kg/m3, 629.25 kg/m3, 404.56 kg/m3, 592.33 kg/m3, and 544.11 kg/m3,t. The average carbon contents of each tree species at different age classes are 51.48%, 46.88%, 47.81%, 46.76%, and 47.24%. It showed a significant difference between the above tree species through variance test. The maximum values of average carbon storage are 70a, 40a, 30a, 48.7a, and 49.2a, respectively. The corresponding average carbon storages are A 2.527 kg, B 3,794 kg, C 2.781 kg, D 2.996 kg, and E 3,322 kg, in a descending order ofC>E>D>B>A. This research, through experiment on four tree species with clear growth rings and one tree species with unclear growth rings, verified the scientific character and the scope of application of the carbon storage dynamic analysis method, providing a new method for the measurement and analysis of forest carbon storage.
