Effect of density and management of oil palm plantations on the avifauna of Southeastern Sierra Leone

November 2023

Oil palm (Elaeis guineensis) is a tropical perennial plant that provides most of the vegetable oil traded internationally. Although native to Africa, oil palm is grown throughout the humid tropics, and the largest producers are now in Southeast Asia. In many regions of cultivation, oil palm has been identified as a leading cause of deforestation and biodiversity loss. In Sierra Leone, oil palm grows wild in secondary...
