Forests


25.4% of Nepal's land area, or about 36,360 km2 (14,039 sq mi) is covered with forest according to FAO figures from 2005. FAO estimates that around 9.6% of Nepal's forest cover consists of primary forest which is relatively intact. About 12.1% Nepal's forest is classified as protected while about 21.4% is conserved according to FAO. About 5.1% Nepal's forests are classified as production forest. Between 2000-2005, Nepal lost about 2,640 km2 (1,019 sq mi) of forest. Nepal's 2000-2005 total deforestation rate was about 1.4% per year meaning it lost an average of 530 km2 (205 sq mi) of forest annually. Nepal's total deforestation rate from 1990-2000 was 920 km2 (355 sq mi) or 2.1% per year. The 2000-2005 true deforestation rate in Nepal, defined as the loss of primary forest, is -0.4% or 70 km2 (27 sq mi) per year.
Deforestation is driven by multiple processes. In the hills, conversion of forests to agricultural land—even on steep hillsides via terracing—is historically important, but has lessened in recent decades due to a shortage of remaining suitable terrain in the hills while mosquito suppression having opened formerly malarial land for settlement in the Terai. As a result, forest land in the Terai is being cleared by settlers.
In the hills, greater contemporary impacts involve degradation of forests rather than outright clearing. Degradation is caused by harvesting firewood, and to a lesser extent wood for traditional architecture. These harvests are often carried to unsustainable levels. Trees are also severely damaged by intensive harvesting of leaves as fodder, especially in the driest months preceding the summer monsoon. Households typically keep at least one cow or buffalo for milk production and may also keep oxen for agricultural labor. In addition goats are herded as the main source of meat that is culturally acceptable to upper-caste Hindus.
