Conifer forests are especially abundant in the boreal and temperate regions of the Northern Hemisphere, but are also important components of many tropical and sub-tropical forest ecosystems in both humid and semi-arid zones. In 1995, almost two thirds of the world’s total industrial roundwood production came from conifers according to the statistics in FAO’s Forest ProductsYearbook. In addition to their huge wood production potential, many conifers are capable of providing a wide range of non -wood products that are of great benefit to human society.
