Carbon emissions and reflection are some of the most significant and urgent environmental problems in the world today due to climate change, and because of their ability to sequester Carbon, trees significantly reduce the amount of carbon dioxide in the atmosphere. This study used a non-destructive method to evaluate the capacity of twenty-seven species of woody trees from 16 distinct families to sequester Carbon in Makurdi Zoological Garden in Benue State. A girt measuring tape was used to measure DBH (diameter at breast heights) at 1.3 meters above ground, a haga altimeter was utilized in measuring the Height of trees and the estimation of AGB (above-ground biomass) was performed using the pantropical allometric equation. The results indicated that the twenty-seven tree species under study yielded 1512.7 tons/ha and 302.5 tons/ha of AGB and BGB, respectively. Additionally, 756.6 and 151.29 tons/ha for AGC and BGC were recorded, respectively. Poisson regression analysis shows significant deviance among the parameters studied (p ≤ 0.005), Pearson correlation analysis shows strong positive correlations (1.000) between total Carbon sequestered and total ground Carbon, total ground Carbon, total below-ground Biomass and total above-ground Biomass, among others, and cluster analysis revealed 8 distinct clusters. This investigation showed how much carbon woody trees sequester and highlighted the importance of measuring the amount of Carbon stored by woody trees regularly, as this allows one to calculate the amount of CO2 released into the atmosphere.
