"Primary forests account for 36% of forest area - but 6 million hectares are lost or modified each year. On a global average, more than one-third of all forests are primary forests (defined as forests of native species where there are no clearly visible indications of human activities and where the ecological processes are not significantly disturbed). The rapid decrease of primary forest area reported for the 1990s continued in 2000-2005. This decrease stems not only from deforestation, but also from modification of forests due to selective logging and other human interventions." -- from United Nations, Forest Resources Assessment 2005
