In Asia, two species are widely harvested, Korean Pine (Pinus koraiensis) in northeast Asia and Chilgoza Pine (Pinus gerardiana) in the western Himalaya. Four other species, Siberian Pine (Pinus sibirica), Siberian Dwarf Pine (Pinus pumila), Chinese White Pine (Pinus armandii) and Lacebark Pine (Pinus bungeana) are also used to a lesser extent. In North America the main species are three of the pinyon pines, Colorado Pinyon (Pinus edulis), Single-l
