Agroforestry practice play a crucial role for carbon regulation through carbon sequestration. Trees in agroforestry practice have received much attention recently due to their contribution for mitigate climate change . This study aimed at estimation of carbon stock in homegarden and parkland agroforestry practices. Accordingly, sixty plots (i.e. thirty 50m by 20 m plots were laid in parkland and thirty, 30 m by 30 m plots were laid in homegarden). Diameter at Breast Height (DBH) and height were measured for trees and shrubs who’s DBH?5 cm. In total 37 species belonging to 33 genera and 20 families were identified. Considering each agroforestry alone, 25 species in homegarden and 21 species in parkland were identified. The result showed that 8 species were common for all two agroforestry practices. Shannon-Wiener diversity indices indicated 2.25 and 2.21 for homegarden and parkland, respectively showing a true diversity of 9.5 and 9.1. The basal areas in homegarden and parkland were 9.39 m2/ha and 3.58 m2/ha, respectively. The total density of Multipurpose Tree Species (MPTS) species in homegarden and parkland were 185 and 51 individuals’ ha-1, respectively. Total biomass and the carbon content revealed 2.90 Mg/ha and 1.5 MgC/ha for homegarden, 2.0 Mg/ha and 1.0 MgC/ha for parkland, respectively.
