Woodlot tree species are trees planted or naturally growing in small-scale and or managed forested areas. The study was conducted on four woodlot agroforestry tree species; Grevillea robusta, Cordia africana, Cupressus lusitanica and Casuarina equisetifolia at Yabello Agriculture Research Center to evaluate their adaptability and growth performances. The experiment was laid out in RCBD with three replications. The result of this study revealed that, there was a significant difference among the tree species (P<0.05) in survival rate. All of the tested species; Grevalia robusta, Cupressus lusitanica, Casuarina equisetifolia and Cordia africana showed the highest performance in terms of survival rate 99.07%, 76.85%, 69.7% and 67.59% respectively. The mean plant height of Grevillea robusta, Cordia africana, Cupressus lusitanica and Casuarina equisetifolia were 5.92m, 4.46m, 4.03m and 2.75m respectively. The mean diameter at breast height for Grevillea robusta, Cordia africana, Cupressus lusitanica and Casuarina equisetifolia were 6.39cm, 6.63cm, 4.44cm and 2.19cm respectively. The mean canopy diameter of Grevalia robusta, Cupressus lusitanica, Casuarina equisetifolia and Cordia africana were 3.2m, 3.02m, 1.36m and 3.91m respectively. Generally, the mortality of some seedlings of all species might be explained as a response to low moisture and soil condition of the study area. Therefore, in the study under Yabello and related agroecology, planting of these better performing tree species and encouraging their promotion were recommended as they are important for timber, fuel wood, construction, soil conservation, shading, forage, and in general as multi-purpose trees in the area.
