Deforestation, both for commercial timber and to make room for agriculture, is the major concern and represents an enormous loss of natural economic wealth to the nation. Mining and slash and burn for land conversion – such as cattle grazing – dramatically diminished forested land in Sierra Leone since the 1980s. It is listed among countries of concern for emissions, as having Low Forest Cover with High Rates of Deforestation (LFHD). There are concerns that heavy logging continues in the Tama-Tonkoli Forest Reserve in the north. Loggers have extended their operations to Nimini, Kono District, Eastern Province; Jui, Western Rural District, Western Area; Loma Mountains National Park, Koinadougu, Northern Province; and with plans to start operations in the Kambui Forest reserve in the Kenema District, Eastern Province. The country had a 2019 Forest Landscape Integrity Index mean score of 2.76/10, ranking it 154th globally out of 172 countries.
