Erosion and cutting, chiefly for fuel, have almost entirely eliminated Burundi's forests. The harvesting of wood has increased only slightly since the late 1970s, and the emphasis has now shifted to reforestation. Forests and woodlands cover an estimated 325,000 hectares (803,000 acres). Natural forest covers 67,000 hectares (165,600 acres). Forestry output should continue to grow as the result of a World Bank-sponsored tree-planting program. Of an estimated 5.8 million cu m (205 million cu ft) in roundwood production in 2000, 99% was for fuel.
