Pine Nut - Species and Geographic Spread

Species and Geographic Spread

In Asia two species are widely harvested, Korean Pine (Pinus koraiensis) in northeast Asia (the most important species in international trade), 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. Afghanistan is an important source of pine nuts.

Pine nuts produced in Europe mostly come from the Stone Pine (Pinus pinea), which has been cultivated for its nuts for over 6,000 years, and harvested from wild trees for far longer. The Swiss Pine (Pinus cembra) is also used to a very small extent.

In North America, the main species are three of the pinyon pines, Colorado Pinyon (Pinus edulis), Single-leaf Pinyon (Pinus monophylla), and Mexican Pinyon (Pinus cembroides). The other eight pinyon species are used to a small extent, as are Gray Pine (Pinus sabineana), Coulter Pine (Pinus coulteri), Torrey Pine (Pinus torreyana), Sugar Pine (Pinus lambertiana) and Parry Pinyon (Pinus quadrifolia).

In the United States, pine nuts are mainly harvested by Native Americans, particularly the Uto-Aztecan: Shoshone, Paiute and Hopi, and Washoe tribes. Certain treaties negotiated by tribes and laws in Nevada guarantee Native Americans' right to harvest pine nuts.
