A Comparative empirical assessment of native deciduous and evergreen trees on carbon stock potential for regulating ecosystem services in tropical dry evergreen forest, Coromandel coast, Tamil Nadu, India Parisutha Rajan Alphonse Marianadin 1 ,School of Planning and Architecture, Vijayawada (India) Minakshi Jain, School of Planning and Architecture, Vijayawada (India) Abdul Razak Mohamad, School of Planning and Architecture, Vijayawada (India) ABSTRACT Vegetation, particularly trees, provides a wide spectrum of regulating ecosystem services, which include up keeping of air quality, stabilizing temperature, reduction in ultraviolet radiation, oxygen generation, and carbon sequestration. Carbon Stock, call ed “C-stock”, is one of the most common benefits of trees in today’s scenario on climate change and anthropogenic disturbance all over the world. The purpose of this technical paper is to compare empirically and assess the total C-stock (TCS) of ten dominant native deciduous trees (NDT) and native evergreen trees (NET) for 10-ha area distributed 1-ha in each of ten tropical dry evergreen forest sites of Coromandel Coast of Tamil Nadu, India. The data obtained from a recent research publication is analyzed for total c-stock potential between NDT and NET trees through the application of the statistical tool. The Chi-square, Goodness of fit between Above Ground Biomass of NDT and NET is 30733.80, The p-value is < 0.00001. The result is significant at p < .05 (standard level for analysis). Hence, native evergreen trees have a higher c-stock capacity, when compared to native deciduous trees. Thus, prove the higher carbon sequestration potential of native evergreen trees. Keywords: above ground biomass, below ground biomass, total biomass, carbon stock Introduction Forests, the largest carbon pool on earth, act as a major sink of carbon in nature. Woodland plays an important role in regulating ecosystem services, especially in carbon sequestration. Woody plant species sequester atmospheric carbon into their biological system during photosynthesis and storing excess carbon as “biomass”. Especially, tropical forest ecosystems have the potential to hold and sequester large amounts of carbon than the other biomes. Living biomass of trees plays as main carbon pool in tropical forest ecosystem. Study of literature reveals that tropical forests comprise of 40% of the total terrestrial carbon stock on the planet. Carbon sequestration refers to the annual rate of Carbon-di-oxide storage, called as C-stock in above and below-ground biomass. The carbon stored in the AGB of trees is the largest pool. The estimation of AGB carbon is therefore, the most critical step in quantifying carbon stocks and fluxes from tropical forests. Increasing the number of trees can therefore slow the accumulation of atmospheric carbon, a contributor to climate change. The ability of a tree to sequester carbon changes over time as it grows. The key urban forest parameters reported to improve carbon sequestration and storage 1 Corresponding Author: [parisutharajan@gmail.com] -- 800 -- Conference Proceedings of 5th International Conference on Countermeasures to Urban Heat Islands (IC2UHI) 2019 December 2-4, 2019, Hyderabad, India https://doi.org/10.37285/bsp.ic2uhi.50
